Having been driven out of France, the Spanish Goths formally embraced Nicene Christianity at the Third Council of Toledo in 589.
During the 3rd century, East Germanic people, moving in a southeasterly direction, migrated into the Dacians' territories previously under Sarmatian and Roman control, and the confluence of East Germanic, Sarmatian, Dacian and Roman cultures resulted in the emergence of a new Gothic identity.
Even as late as 406, a Gothic king by the name of Radagaisus led a Pagan invasion of Italy with fierce anti-Christian views.
The initial success experienced by the Goths encouraged them to engage in a series of raiding campaigns at the close of the 3rd century, many of which resulted in having numerous captives sent back to Gothic settlements north of the Danube and the Black Sea.
Ulfilas, who became bishop of the Goths in 341 AD, was the grandson of one such female Christian captive from Sadagolthina in Cappadocia.
Eusebius was a pupil of Lucian of Antioch and a leading figure of a faction of Christological thought that became known as Arianism, named after his friend and fellow student, Arius.Between 348 and 383, Ulfilas likely presided over the translation of the Bible from Greek into the Gothic language, which was performed by a group of scholars.
Gothic probably persisted as a liturgical language of the Gothic-Arian church in some places even after its members had come to speak Vulgar Latin as their mother tongue.
