Easter Controversy
The controversy over the correct date for Easter began in Early Christianity as early as the 2nd century AD. Discussion and disagreement over the best method of computing the date of Easter Sunday has been ongoing ever since and remains unresolved. Different Christian denominations continue to celebrate Easter on different dates, with Eastern and Western Christian churches being a notable example. Quartodecimanism Quartodecimanism (from the Vulgate Latin ''quarta decima'' in Leviticus 23:5, meaning fourteenth) is the practice of celebrating Easter on the 14th of Nisan at the same time as the Jewish Passover. Quartodecimanism caused two schisms, one headed by Blastus in Rome and one headed by Polycrates in the East. First Council of Nicaea in 325 In 325 an ecumenical council, the First Council of Nicaea, established two rules: independence from the Jewish calendar, and worldwide uniformity. However, it did not provide any explicit rules to determine that date, writing on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Christianity

Hebrew Calendar
The Hebrew calendar (), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates of Jewish holidays and other rituals, such as '' yahrzeits'' and the schedule of public Torah readings. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar. Like other lunisolar calendars, the Hebrew calendar consists of months of 29 or 30 days which begin and end at approximately the time of the new moon. As 12 such months comprise a total of just 354 days, an extra lunar month is added every 2 or 3 years so that the long-term average year length closely approximates the actual length of the solar year. Originally, the beginning of each month was determined based on physical observation of a new moon, while the decision of whether to add the leap month was based on observation ...

Eastern Orthodox Church
The Eastern Orthodox Church, officially the Orthodox Catholic Church, and also called the Greek Orthodox Church or simply the Orthodox Church, is List of Christian denominations by number of members, one of the three major doctrinal and jurisdictional groups of Christianity, with approximately 230 million baptised members.

Vernal Equinox (Northern Hemisphere)
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox (or spring equinox) in the Northern Hemisphere and as the autumnal equinox (or fall equinox) in the Southern Hemisphere. On the Gregorian calendar at 0° longitude, the northward equinox can occur as early as 19 March (which happened most recently in 1796, and will happen next in 2044), and it can occur as late as 21 March (which happened most recently in 2007, and will happen next in 2102). For a common year the computed time slippage is about 5 hours 49 minutes ''later'' than the previous year, and for a leap year about 18 hours 11 minutes ''earlier'' than the previous year. Balancing the increases of the common years against the losses of the leap years keeps the calendar date of the March equinox from drifting more than one ...

Julian Calendar
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodox Churches, Oriental Orthodoxy as well as by the Amazigh, Amazigh people (also known as the Berbers). The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar, as a reform of the earlier Roman calendar, which was largely a lunisolar calendar, lunisolar one. It took effect on , by his edict. Caesar's calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years, until 1582 when Pope Gregory XIII promulgated a revised calendar. Ancient Romans typically designated years by the names of ruling consuls; the ''Anno Domini'' system of numbering years was not devised until 525, and became widespread in Europe in the eighth cent ...

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...

Columbanus
Saint Columbanus (; 543 – 23 November 615) was an Irish missionary notable for founding a number of monasteries after 590 in the Frankish and Lombard kingdoms, most notably Luxeuil Abbey in present-day France and Bobbio Abbey in present-day Italy. Columbanus taught an Irish monastic rule and penitential practices for those repenting of sins, which emphasised private confession to a priest, followed by penances imposed by the priest in reparation for the sins. Columbanus is one of the earliest identifiable Hiberno-Latin writers. Sources Most of what we know about Columbanus is based on Columbanus' own works (as far as they have been preserved) and Jonas of Susa's ''Vita Columbani'' (''Life of Columbanus''), which was written between 639 and 641. Jonas entered Bobbio after Columbanus' death but relied on reports of monks who still knew Columbanus. A description of miracles of Columbanus written by an anonymous monk of Bobbio is of much later date.O'Hara, Alexander, an ...

Bede
Bede (; ; 672/326 May 735), also known as Saint Bede, Bede of Jarrow, the Venerable Bede, and Bede the Venerable (), was an English monk, author and scholar. He was one of the most known writers during the Early Middle Ages, and his most famous work, '' Ecclesiastical History of the English People'', gained him the title "The Father of English History". He served at the monastery of St Peter and its companion monastery of St Paul in the Kingdom of Northumbria of the Angles. Born on lands belonging to the twin monastery of Monkwearmouth–Jarrow in present-day Tyne and Wear, England, Bede was sent to Monkwearmouth at the age of seven and later joined Abbot Ceolfrith at Jarrow. Both of them survived a plague that struck in 686 and killed the majority of the population there. While Bede spent most of his life in the monastery, he travelled to several abbeys and monasteries across the British Isles, even visiting the archbishop of York and King Ceolwulf of Northumbria. ...

Pope Gregory I
Pope Gregory I (; ; – 12 March 604), commonly known as Saint Gregory the Great (; ), was the 64th Bishop of Rome from 3 September 590 until his death on 12 March 604. He is known for instituting the first recorded large-scale mission from Rome, the Gregorian mission, to convert the then largely pagan Anglo-Saxons to Christianity. Gregory is also well known for his writings, which were more prolific than those of any of his predecessors as pope. The epithet Saint Gregory the Dialogist has been attached to him in Eastern Christianity because of his '' Dialogues''. English translations of Eastern texts sometimes list him as Gregory "Dialogos" from the Greek (''dialogos'', conversation), or the Anglo-Latinate equivalent "Dialogus". He is the second of the three Popes listed in the ''Annuario Pontificio'' with the title "the Great", alongside Popes Leo I and Nicholas I. A Roman senator's son and himself the prefect of Rome at 30, Gregory lived in a monastery that he establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
