Exile
Exile is primarily penal expulsion from one's native country, and secondarily expatriation or prolonged absence from one's homeland under either the compulsion of circumstance or the rigors of some high purpose. Usually persons and peoples suffer exile, but sometimes social entities like institutions (e.g. the papacy or a government) are forced from their homeland. In Roman law, ''exsilium'' denoted both voluntary exile and banishment as a capital punishment alternative to death. Deportation was forced exile, and entailed the lifelong loss of citizenship and property. Relegation was a milder form of deportation, which preserved the subject's citizenship and property. The term diaspora describes group exile, both voluntary and forced. "Government in exile" describes a government of a country that has relocated and argues its legitimacy from outside that country. Voluntary exile is often depicted as a form of protest by the person who claims it, to avoid persecution and prosecu ...

Baptism
Baptism (from grc-x-koine, βάπτισμα, váptisma) is a form of ritual purification—a characteristic of many religions throughout time and geography. In Christianity, it is a Christian sacrament of initiation and adoption, almost invariably with the use of water. It may be performed by sprinkling or pouring water on the head, or by immersing in water either partially or completely, traditionally three times, once for each person of the Trinity. The synoptic gospels recount that John the Baptist baptised Jesus. Baptism is considered a sacrament in most churches, and as an ordinance in others. Baptism according to the Trinitarian formula, which is done in most mainstream Christian denominations, is seen as being a basis for Christian ecumenism, the concept of unity amongst Christians. Baptism is also called christening, although some reserve the word "christening" for the baptism of infants. In certain Christian denominations, such as the Lutheran Churches, baptism ...

Anna Of East Anglia
Anna (or Onna; killed 653 or 654) was king of East Anglia from the early 640s until his death. He was a member of the Wuffingas family, the ruling dynasty of the East Angles, and one of the three sons of Eni who ruled the kingdom of East Anglia, succeeding some time after Ecgric was killed in battle by Penda of Mercia. Anna was praised by Bede for his devotion to Christianity and was renowned for the saintliness of his family: his son Jurmin and all his daughters – Seaxburh, Æthelthryth, Æthelburh and possibly a fourth, Wihtburh – were canonised. Little is known of Anna's life or his reign, as few records have survived from this period. In 631 he may have been at Exning, close to the Devil's Dyke. In 645 Cenwalh of Wessex was driven from his kingdom by Penda and, due to Anna's influence, he was converted to Christianity while living as an exile at the East Anglian court. Upon his return from exile, Cenwalh re-established Christianity in his own kingdom and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

He was an author, teacher (Alcuin was a student of one of his pupils), and scholar, and his most famous work, ''Ecclesiastical History of the English People ...
