'' which states in regards to faith and science:
Though faith is above reason, there can never be any real discrepancy between faith and reason. Since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can truth ever contradict truth. ... Consequently, methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God despite himself, for it is God, the conserver of all things, who made them what they are.

The theory of conflict between science and the Church

This view of the Church as a patron of sciences is contested by some, who speak either of a historically varied relationship which has shifted, from active and even singular support to bitter clashes (with accusations of heresy) – or of an enduring intellectual conflict between religion and science. Enlightenment philosophers such as
Voltaire François-Marie Arouet (; 21 November 169430 May 1778) was a French Enlightenment writer, historian, and philosopher. Known by his '' nom de plume'' M. de Voltaire (; also ; ), he was famous for his wit, and his criticism of Christianity—e ...

. An alternative criticism is that the Church opposed ''particular'' scientific discoveries that it felt challenged its authority and power – particularly through the Reformation and on through the Enlightenment. This thesis shifts the emphasis away from the perception of the fundamental incompatibility of religion ''per se'' and science-in-general to a critique of the structural reasons for the resistance of the Church as a political organization. The Church itself rejects the notion of innate conflict. The Vatican Council (1869/70) declared that "

summarised the Catholic view of the relationship between faith and reason in the encyclical '' Fides et Ratio'', saying that "faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth – in a word, to know himself – so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves." The present Papal astronomer Brother Guy Consolmagno describes science as an "act of worship" and as "a way of getting intimate with the Creator."

Definitions of science

Differing analyses of the Catholic relationship to science may arise from definitional variance. While secular philosophers consider "science" in the restricted sense of natural science, in the past theologians tended to view science in a very broad sense as given by

Some of this study was carried out for explicitly religious reasons. The need for monks to determine the proper time to pray led them to study the motion of the stars; the need to compute the date of Easter led them to study and teach rudimentary mathematics and the motions of the Sun and Moon.

Roman Inquisition

In the Middle Ages of the Roman Church, Pope Paul III (1468-1549) initiated the Congregation of the Roman Inquisition in 1542, which is also known as the Holy Office. A large expansion of Protestantism began to spread all throughout Italy, which triggered Pope Paul III to act against it. He would be the first to create proactive reforms for the sake of Roman Catholicism. Evidently the reforms would be strict rulings against foreign ideologies that would fall outside of their religious beliefs. The Inquisition would soon be under the control of

as such practices were seen in 1484 where Pope Innocent stated it was an act of going against the church. Any ideologies that was outside of their norm beliefs was seen as a threat and needed to be corrected even if it was through torture.


Inquisition Tactics and Practices

Pope Sixtus V put forth 15 congregations. The inquisition would imprison anyone who was seen as a threat towards the Catholic Church or placed onto house arrest. They kept a tight security and denied any other religious foreigners from coming inside their regions. Papal policies were implemented to stop foreigners from showing their practices to the public. The Index of Forbidden Books was used to prevent people from doing magic and to suppress books deemed heretical, politically disruptive, or threatening to public morals. To stray away from this would allow for one to not be "infected". Punishment was acceptable and torture tactics were used in order for one to confess their sins.


The Fall of the Inquisition

In the 18th century, witchcraft and other groups became less of a threat to the Catholic Church. The focus moved to

and his heliocentric theory and is defined as the beginning of a dramatic shift in thought and belief towards scientific theory. The Scientific Revolution began in Western Europe, where the Catholic Church had the strongest holding. It is believed that the Scientific Revolution began in Western Europe because of the freedom to pursue other ideas provided by most European Universities and which go against Church authorities. Western Europe was also a central 'melting pot' for foreign knowledge and cultural beliefs including ancient Chinese math, Islamic philosophy, and Arabic astrology. Posed by author Peter Dear, the revolution can be thought of in two parts: the Scientific Renaissance and the revolution. The renaissance is considered the actual rebirth of the ideas, where mathematics, philosophy, astronomy, and physics were all being rediscovered in a sense. Following this rediscovery, people began to question the ideas of the church (which could be considered antique). Dear also references the fact that when historians study the relationship between scientists and the Church, they are not taking the standpoint that either view is true, instead they look at it the reasons they believed their side and then "Find out; truth or falsity are determined by arguments and it is the arguments that can be studied historically." The Scientific Revolution and its challenging of the Church's ideas were followed by the Period of Enlightenment where people not only question the Church's ideas but also began to question their authority. The central theme of this period is that human society "could be changed and improved by human action guided by reason" as stated by

's leap month system, the Council of Nicaea prescribed that Easter would fall on the first Sunday following the first full moon after the vernal equinox. Thus, it became necessary that the Church have the capacity to predict the date of Easter with enough accuracy and forewarning to allow both for sufficient time to prepare for the feast as well as ensure the universal celebration of the holy day across all of the Church's dominion – a daunting logistical feat. This necessity fueled constant innovation and refinement of astronomical practice as the solar and lunar years diverge over centuries. The Church's dedication to ever-increasingly accurate astronomy led to developments in ancillary disciplines. In the 12th century, the church helped re-popularize and disseminate ancient Greek ideas and mathematical techniques across Europe by sponsoring the translation of newly available Arabic-language version of Greek texts into Latin. This was done in large part to aid in astronomical study. In the late 16th century, the Church encouraged the inclusion of pinhole cameras into the construction of churches. Pinhole cameras are among the best tools for measuring the time between solstices. The transformation of churches into solar observatories encouraged innovations in engineering, architecture, and construction, and fueled the careers of astronomers like Cassini.

, although the specific ban on uncensored versions of the ''Dialogue'' and Copernicus's ''De Revolutionibus'' remained. Heilbron (2005, p.307); Coyne (2005, p.347) The practical effect of the ban in its later years seems to have been that clergy could publish discussions of heliocentric physics with a formal disclaimer assuring its hypothetical character and their obedience to the Church decrees against the motion of the earth: see for example the commented edition (1742) of Newton's 'Principia' by Fathers Le Seur and Jacquier, which contains such a disclaimer ('Declaratio') before the third book (Propositions 25 onwards) dealing with the lunar theory. All traces of official opposition to heliocentrism by the Church disappeared in 1835 when these works were finally dropped from the Index. McMullin (2005, p.6); Coyne (2005, p.346). The Church's opposition had effectively ended in 1820 when a Catholic canon, Giuseppe Settele, was permitted to publish a work that treated heliocentrism as a physical fact rather than a mathematical fiction. The 1835 edition of the Index was the first to be issued after that year.

The Catholic Church as a Strategic and Careful Patron of Science

The relationship between the Catholic church and science has been largely supportive in spite of the myth of conflict stemming from discomfort with divergence from a Biblical
geocentric model In astronomy, the geocentric model (also known as geocentrism, often exemplified specifically by the Ptolemaic system) is a superseded description of the Universe with Earth at the center. Under most geocentric models, the Sun, Moon, stars, an ...
of cosmology to a heliocentric one. The church and its Jesuit missionaries not only studied subjects such as astronomy, physics and math, they exchanged information with others such as the Chinese across the world. In 1616, the Qualifiers of the Holy Office formally disavowed heliocentric theory. However, when they needed assistance with a problematic Ecclesiastical calendar, they solicited the assistance of astronomers who inadvertently proved the validity of it. Two developments made the confirmation possible: the more accurate measurements of the sun and the moon, and the astronomical community's understanding of how to use language that was vague enough to avoid direct conflict with church doctrine. Words in Biblical scripture left some room for interpretation and when there were conflicts between the physical and the scriptural, both the church and the scientists engaged in exercises of hermeneutical accommodation.


= Example of Church Sponsorship of Astronomical Research-Ecclesiastical Calendaring

= One of the primary reasons that the church was so supportive of astronomical research was that the church needed astronomers to assist in resolving issues with the calendar—specifically in establishing a date for

. In 325 A.D., the Catholic theologians comprising the Council of Nicaea, set the date of Easter as the first Sunday after the first full moon of the vernal equinox where the vernal equinox was the point of equal daylight and darkness.Öberg, Karin I. (2009). ''Complex processes in simple ices - Laboratory and observational studies of gas-grain interactions during star formation'' (Ph.D.). Leiden Universit

/ref>  The challenge in using astronomical observations for a religious celebration spanning great distances across the globe was that date was inconsistent and subject to errors in accuracy of observations. Beyond the challenge of Easter was the fact that the calendar was used for business that included payment schedules, etc. thus creating economic consequences every time days were removed for realignment purposes. By the sixth century, there was papal pressure to create a system for designating the date of Easter that was both accurate and consistent across the world. The church recognized that there had been a drift and that the date of Easter no longer seemed to align with heaven which created an urgent need to understand the movement of the sun and earth so that the calendar conflicts could be resolved. After reviewing the data from Aristotle to Ptolemy, they recognized that the problem centered on the period between successive Spring equinoxes. In 1514, Pope Leo X commissioned Dutch astronomer Paul of Middleburg to identify a resolution. Paul favored resetting the date of the vernal equinox to March 10 rather than eliminating days to correct the drift but the changes were not made. Copernicus, a contemporary of Paul, attributed the failure to inaccuracies in measurements of the sun and moon and he focused his attention on collecting more accurate data. Accurate data about the vernal equinox required a large, dark space like a cathedral to measure a meridian line. A hole was cut into the roof of a cathedral and using a rod or line in the floor, they measured the time it took for a noon time image of the sun to return to the same place. The accuracy depended on the quality of the laboratory set up for observation, including the location of the hole, the level of the floors and line placement. Cosimo de' Medici, Cosimo I D’Medici a patron of the arts and supporter of the church, enlisted Egnatio Danti, a Dominican artist, for help with the calendar. Danti found the perfect location for his meridian in the Basilica di San Petronio in Bologna. Structural issues led to inaccuracy of Danti's meridian. Decades later,

's “bisection of eccentricity” using the diameter of the sun's image as an inverse substitute for the sun's distance from the earth. His precise work ended up proving the validity of Copernican theory condemned by the church. After Galileo, scientists consciously identified ways to stay in alignment with the church as much as possible.


Avoiding Conflict in Sponsorship of Scientific Research-Hermeneutical Accommodation

Astronomers from Ptolemy to Cassini recognized potential conflicts between their observations and cosmology and it was often a challenge to cultivate a position in which science and scripture could both be true. Ptolemy saw the conflict between his model and the movement of planets. By interpreting the word orbit in both a geometric sense and in a way that could apply to the sun or the earth, Catholic scientists like Cassini could create enough distance from Galileo's theory to operate without condemnation from the church. Galileo himself felt that conflict between scripture and science could be resolved through hermeneutical accommodation. He believed that there could essentially be harmony between science or nature and scripture if one understood how to interpret scripture. Galileo was of the opinion that since God is responsible for every aspect of our world, including the sensory experiences that are an integral part of scientific observation, then if what we see differs from scripture, we should conclude that the observations are correct.

to further emphasize Copernicus's astronomical system that was already being theorized. While Osiander would be coming from a Lutheran stance and Copernicus's system was in alignment with the Catholic canon. He found that Copernicus's system also coincided with Lutheran ideologies. The part that Osiander played in counteracting the critique was by writing the foreword or rather preface of Copernicus's book to refrain it from getting questioned, within the preface he essentially alluded to the fact that Copernicus's system may be mathematically accurate and therefore would be true, but states that it is all a theory. By Osiander writing the foreword and making this statement he was "saving the phenomenon" and was able to keep Copernicus's work from getting questioned to an extent ."Saving the phenomenon" was when scientists found reason to interpret or decode a theory in a more technical way and could further be contested with other theories. The part in which the foreword played further developed and helped bring to light the separation of both science and cosmology. Making that distinction furthered helped expand upon theories that would rub the Church in the wrong way, but avoided that because by focusing on the mathematical aspects and not making quick conclusions about how planets moved kept a boundary intact between the two and helped refrain a conflict from occurring. The Church has, since ancient times, been heavily involved in the study and provision of medicine. Early Christians were noted for tending the sick and infirm, and priests were often also physicians.

However, recent scholarship in the history of science has focused on the substantial contributions of Jesuit scientists over the centuries. Historian Jonathan Wright discussed the breadth of Jesuit involvement in the sciences in his history of the order:
he Jesuitscontributed to the development of pendulum clocks, pantographs, barometers, reflecting telescopes and microscopes, to scientific fields as various as magnetism, optics, and electricity. They observed, in some cases before anyone else, the colored bands on Jupiter's surface, the Andromeda nebula, and Saturn's rings. They theorized about the circulation of the blood (independently of Harvey), the theoretical possibility of flight, the way the moon affected the tides, and the wave-like nature of light. Star maps of the southern hemisphere, symbolic logic, flood-control measures on the Po and Adige rivers, introducing plus and minus signs into Italian mathematics – all were typical Jesuit achievements, and scientists as influential as Fermat, Huygens, Leibniz, and Newton were not alone in counting Jesuits among their most prized correspondents.


Jesuits in China

The Jesuits made significant contributions to scientific knowledge in China. Under the Qing Dynasty, the Jesuits' knowledge of observational astronomy and spherical trigonometry was welcomed by the imperial court. The Manchus who conquered the Ming Dynasty also welcomed the Jesuit scientists and employed their help due to their expert knowledge of mathematical astronomy, which aided the ruling class in predicting celestial events, thus, displaying that this dynasty retained the Mandate of Heaven. In addition to reinforcing the Mandate of Heaven, the Jesuits separated two fields of science that were thought by the Chinese to be the same, cosmology and cosmography. By doing so, they were able to avoid being restricted by the ''Book of Changes''. The Jesuits' astronomical measurements were also more accurate than their Chinese counterparts. This factor, combined with the fact that the Jesuits also sympathized with the need of the Qing Dynasty to replace the old Ming calendar with a better one of their own enabled the Jesuits to make a significant impact on the Chinese Imperial Court. The Jesuits themselves each fulfilled different roles at the imperial court. Father Matteo Ricci served on a jury charged with filling high ranking positions in the imperial court. Father

was made president of the mathematics court of the Qing dynasty and contributed significantly to the reformation of China's calendar. Father Ferdinand Verbiest contributed to China's understanding of its geography and helped China define its border with Russia.


Matteo Ricci

Matteo Ricci was one of the most influential Jesuits that was sent to China. Matteo had been educated in math and science at the Collegio Romano with Christopher Clavius and also in Portugal at the University of Coimbra. Matteo went to China in 1581, where he resided in the city of Macau. He would then move to Beijing in 1601, where he hoped that the Ming would employ him and his order to correct their calendar. Ricci would also spread Euclidean Geometry to China by helping translate his works while using books prepared by Christopher Clavius. Ricci hoped to do this by earning the favor of the court and educated literati elites. In this, Ricci was successful. He was able to convert other Chinese scholars to Catholicism who would then subsequently help him spread both Christianity and more accurate astrological measurements. In one case, Ricci, along with Xu Guangqi and Li Zhizhao, both of whom he had converted, would translate both Euclid and Ptolemy's works into Chinese in 1607. These three would also go on to translate works from both Nicolaus Copernicus and Tycho Brahe. By doing this, they were able to introduce, however slightly new ideas into the Chinese astronomical system. Although the Ming court never took his work seriously while he was still alive, one of Ricci's converts, Xu Guangqi would later be called upon as a high-ranking member of the Ministry of Rites and he would go on to reform the Chinese astronomical system.


Johann Adam Schall von Bell

Johann Adam Schall von Bell was another influential Jesuit priest that was sent to China. During Schall's stay in China, the Ming dynasty was overthrown and replaced by the Manchu Qing Dynasty. Schall, along with many other Jesuits quickly adapted to the regime change and offered his services to the new Qing Emperor. The new Emperor accepted Schall's offer, and this could bring in a new age of Jesuit acceptance in China that contrasted with the Ming dynasty's indifference to Matteo Ricci's efforts. The acceptance of Jesuit help would go on to have drastic consequences, as the former Chinese and Muslim members of the Astrocaldendrical Bureau who were replaced by the Jesuits would join the anti-Jesuit faction in the court and seek to purge their influence. In the meantime, however, Schall and assistants would continue their work and in 1645, they unveiled their first work. They called it a "temporal model calendar". it heavily borrowed from ''Mathematical Astronomy According to the New Western Methods'', which was a series of Western writings that were translated into Chinese by Xu Guanqi and past Jesuits. Schall, recognizing the importance of elaborate state rituals in China, offered the calendar to the Emperor in a complex ceremony involving music, parades, and signs of submission like kneeling and kowtowing. After this overwhelming success, however, Schall's legitimacy was quickly put into question by Yang Guangxian, who accused Schall of attempting to undermine the Qing dynasty by fomenting civil unrest. Schall and the Jesuits were also accused of secretly harboring illegal foreigners in their churches spread around China and were also accused of claiming that the Qing rulers relied upon their Western ideas for political legitimacy. Schall was imprisoned and died while in captivity in 1666 at the age of seventy-five. He was posthumously pardoned by Kangxi Emperor upon his ascension to the throne.


Ferdinand Verbiest

Ferdinand Verbiest was a Belgian Jesuit who was called upon by the Kangxi Emperor after his ascension to compete in a contest with Muslim astronomers. The contest involved predicting the length of a shadow that would pass over the imperial gnomon, which was a sundial in the Forbidden City. Verbiest won the contest and was subsequently placed at the head of the Astrocalendrical Bureau. As head of the Burea, Verbiest also shared his position with a Manchu, and this tradition would continue until the 1840s. Verbiest claimed that the studying of celestial patterns was of great practical importance to the dynasty and that whether the astronomer in question was Muslim, Jesuit or Chinese didn't matter. He argued that ensuring the observations were impartial and that applying Tycho's ideas to the observations to verify said observations were the two most important factors. Verbiest also claimed that Western ways of measuring data were the most accurate and dismissed the older findings of Chinese astronomers. While these claims did little to convince the Chinese that their old measurements were inaccurate, Verbiest's pushing of spherical trigonometry would go on to have the greatest impact on Chinese astronomy, as they saw it as being connected to when the Mongols brought Islamic astronomy to China during their conquest.

was one of the most prolific members of the order. During his life, he made contributions to algebra, geometry, astronomy, and cartography. Most notable of his accomplishments was his work on the reform of the Gregorian Calendar. Having taught in the Collegio Romano for 40 years, he had a direct impact on the spread of scientific knowledge within the Jesuit order and, from there, an impact on the scientific knowledge of the places his students would visit in their missionary journeys. For example, the Jesuit priest Matteo Ricci translated Clavius' books into Chinese and shared the knowledge they contained with the people of China during his missionary work there. With the help of Clavius' books, Matteo and his fellow Jesuits were able to spread the West's knowledge of astronomy to China which, in turn, led to China's refinement of its calendar system.

was a Jesuit priest who authored around 44 major works and is regarded by some scholars as the founder of Egyptology due to his study of Egyptian hieroglyphs. He is believed by many scholars to be the last "renaissance man" in light of his being a polymath and scholar of a wide range of disciplines including music, astronomy, medicine, geography, and more. Despite providing a wealth of knowledge in his books, Kircher did not contribute much in the way of scientific breakthroughs, but he is credited with the invention of the aeolian harp which was a popular instrument the 19th century One of many notable contributions Athanasius made to the world was his book, China Illustrata in which he gives a detailed record of his observations of Chinese culture and geography—including numerous detailed illustrations plants, statues, temples, and mountains in the vast landscapes of China. Kircher wrote this book based entirely on his study of documents sent back to Rome from his fellow Jesuits in China which led to Kircher being recognized as an expert in China despite having never been there himself.


Pierre Teilhard de Chardin

Pierre Teilhard de Chardin Pierre Teilhard de Chardin ( (); 1 May 1881 – 10 April 1955) was a French Jesuit priest, scientist, paleontologist, theologian, philosopher and teacher. He was Darwinian in outlook and the author of several influential theological and philo ...
was a Jesuit priest who took an interest in geology from a young age. After some time as a professor at the Catholic Institute of Paris, Chardin went on an expedition to China where he performed academic work concerning paleontology and geology. During his travels in China, he played a role in the discovery of the Peking Man's skull. After his research team discovered it, Chardin took part in the examination of the skull and discovered the geological time during which the Peking Man lived. During his time in China, Pierre was able to continue his research of fossils and expanded the scope of geological knowledge in Asia with the help of his fellow Jesuit, Pierre Leroy, who co-founded the Institute of Geobiology with him in Peking.


Pietro Angelo Secchi

Pietro Angelo Secchi became a Jesuit priest in 1833. He became a professor of astronomy at the Roman College and eventually founded an observatory where he would further his research in stellar spectroscopy, meteorology, and terrestrial magnetism. His observations and theories laid the foundation for the Harvard classification system of stars as he was the first to survey the spectra of stars and attempt to classify them by their spectral type.


Jesuit Observatories

Perhaps one of the greatest contributions made by the Jesuits to science is the large network of observatories they founded across the world. Between 1824 and 1957, 75 observatories were founded by the Jesuits. Though their main focus was astronomy, other fields the observatories were involved in include meteorology, geomagnetism, seismology, and geophysiology. In some countries in Asia and Africa, these observatories were the first scientific institutions they had ever had. The contribution of the Jesuits to the development of seismology and seismic prospecting has been so substantial that seismology has been called "The Jesuit Science". Frederick Odenbach, SJ, is considered by many to have been the "pioneer of American seismologists." In 1936, Fr. J.B. Macelwane, SJ, wrote the first seismology textbook in America, ''Introduction to Theoretical Seismology''. In the 21st Century, Jesuits remain prominent in the sciences through institutions like the Vatican Observatory and

Paul IV

For being a Protestant, Conrad Gessner's work, ''Historiae animalium,'' was put on the Index of Prohibited Books by Paul IV.


Gregory XIII

The Gregorian calendar was introduced by Gregory XIII, after whom the calendar was named, by a decree signed on 24 February 1582.


Urban VIII

Urban VIII had Galileo's book put on the Index of Prohibited Books and had Galileo sentenced to lifelong house arrest for heresy for "following the position of Copernicus, which is contrary to the true sense and authority of ''Holy Scripture.''"


Leo XIII

On 18 November 1893, Leo XIII issued ''Providentissimus Deus.'' In it, he said that "no real disagreement can exist between the theologian and the scientist provided each keeps within his own limits. ...If nevertheless there is a disagreement ... it should be remembered that the sacred writers, or more truly ‘the Spirit of God who spoke through them, did not wish to teach men such truths (as the inner structure of visible objects) which do not help anyone to salvation’; and that, for this reason, rather than trying to provide a scientific exposition of nature, they sometimes describe and treat these matters either in a somewhat figurative language or as the common manner of speech those times required, and indeed still requires nowadays in everyday life, even amongst most learned people."

Pius XII

In 1939, Pius XII described Galileo as being among the "most audacious heroes of research ... not afraid of the stumbling blocks and the risks on the way, nor fearful of the funereal monuments." In the 1950 encyclical ''Humani generis,'' Pius XII accepted evolution as a ''possibility'' (as opposed to a ''probability'') and a legitimate field of study to investigate the origins of the human body – though it was stressed that "the Catholic faith obliges us to hold that souls are immediately created by God." In


John Paul II

John Paul II said, "faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth – in a word, to know himself – so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves."


Benedict XVI

Pope Benedict XVI Pope Benedict XVI ( la, Benedictus XVI; it, Benedetto XVI; german: link=no, Benedikt XVI.; born Joseph Aloisius Ratzinger, , on 16 April 1927) is a retired prelate of the Catholic church who served as the head of the Church and the sovereig ...

I saw and see how out of the tangle of assumptions the reasonableness of faith emerged and emerges again.

The ''Catechism of the Catholic Church'' asserts: "Methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God despite himself, for it is God, the conserver of all things, who made them what they are."

's theory of a very old earth, challenged the traditional Biblical account of creation taking place 6,000 years ago. Pope Leo XIII wrote that true science cannot contradict scripture when it is properly explained, that errors the Church Fathers made do not demonstrate error in Scripture, and that what seems to be proved by science can turn out to be wrong. The historical-critical method of analyzing scripture questioned the reliability of the Bible. Leo acknowledged the possibility of errors introduced by scribes but forbade the interpretation that only some of the scripture is inerrant, while other elements are fallible. Leo condemned the use that certain scholars made of new evidence, clearly referring to Alfred Firmin Loisy and Maurice d'Hulst, although not by name. At first, both conservatives and liberals found elements in the encyclical to which to appeal.

. 'The Church remains profoundly convinced that faith and reason “mutually support each other”; each influences the other, as they offer to each other a purifying critique and a stimulus to pursue the search for deeper understanding.' 'Similarly, fundamental theology should demonstrate the profound compatibility that exists between faith and its need to find expression by way of human reason fully free to give its assent. Faith will thus be able “to show fully the path to reason in a sincere search for the truth. Although faith, a gift of God, is not based on reason, it can certainly not dispense with it. At the same time, it becomes apparent that reason needs to be reinforced by faith, to discover horizons it cannot reach on its own”.'

in establishing a university without any official religious affiliation. More recently, Thomas E. Woods, Jr., asserts that, despite the widely held conception of the Catholic Church as being anti-science, this conventional wisdom has been the subject of "drastic revision" by historians of science over the last 50 years. Woods asserts that the mainstream view now is that the "Church asplayed a positive role in the development of science ... even if this new consensus has not yet managed to trickle down to the general public." Science historian Ronald L. Numbers corroborates this view, writing that “Historians of science have known for years that White's and Draper's accounts are more propaganda than history. …Yet the message has rarely escaped the ivory tower."Numbers, Ronald L. “Introduction” in ''Galileo Goes to Jail and Other Myths About Science and Religion.''
