Ulfilas Translates the Bible for the Goths

Estimated date

Ulfilas, bishop of the Christian Goths for forty years, is credited by ancient historians with an alphabet for Gothic and a translation of the Scriptures. He held the Homoian creed, which Nicene writers called Arian. A sixth-century copy of the Gothic Gospels survives at Uppsala.

Philostorgius, a fifth-century church historian who admired Ulfilas and whose work survives in a later summary, says that his forebears were Cappadocians carried off in a Gothic raid in the time of the emperors Valerian and Gallienus, and that such captives had first brought Christianity to their captors (Philostorgius, Church History 2.5). His pupil Auxentius says that he was a lector before he was made bishop for the Goths at the age of thirty (Auxentius, Letter on Ulfilas sections on his ordination and flight). Philostorgius adds that he had come to the imperial court on an embassy and was ordained by Eusebius and the bishops with him (Philostorgius, Church History 2.5).

Auxentius relates that after seven years a Gothic ruler began to persecute the Christians, and that Ulfilas led a large body of them across the Danube; the emperor Constantius II received them (Auxentius, Letter on Ulfilas sections on his ordination and flight), and Philostorgius says that they were settled in Moesia (Philostorgius, Church History 2.5). Two centuries later Jordanes knew their descendants, the “Lesser Goths”, as a poor and peaceful people living around Nicopolis ad Istrum at the foot of Mount Haemus (Jordanes, Getica 51.267).

Philostorgius says that Ulfilas gave the Gothic language a written form and translated all the Scriptures except the books of Kings, which he left out because the Goths were warlike enough already (Philostorgius, Church History 2.5). Socrates likewise credits him with inventing the Gothic letters and translating the Scriptures (Socrates, Church History 4.33). Auxentius does not mention the translation, but says that he preached and wrote in Greek, Latin and Gothic (Auxentius, Letter on Ulfilas sections on his teaching and his creed). The longest surviving Gothic text is the Codex Argenteus at Uppsala, a copy of the four Gospels in Gothic written in silver and gold ink on purple parchment in Italy in the early sixth century (Codex Argenteus).

Socrates notes that Ulfilas assented to the creed of Constantinople of 360, which says that the Son is like the Father as the Scriptures teach and forbids speaking of substance at all (Socrates, Church History 2.41). Historians call this position Homoian, from the Greek word for “like”. Auxentius records that he opposed both the Nicene “of one substance” and the compromise “of like substance”, and taught that the Son is God but second to the Father and obedient to him, and the Holy Spirit subject to the Son; he quotes the creed Ulfilas left at his death (Auxentius, Letter on Ulfilas sections on his teaching and his creed). Nicene writers such as Socrates and Theodoret call this teaching Arian (Socrates, Church History 4.33) (Theodoret, Church History 4.33).

He died at Constantinople, aged seventy, after forty years as bishop (Auxentius, Letter on Ulfilas sections on his death at Constantinople). Theodoret, in the next century, says that the Goths still held that the Father is greater than the Son (Theodoret, Church History 4.33). For the later history of this teaching among the Visigoths see the Visigoths Turn Catholic at Toledo.

How this is dated

Estimated date. A scholarly estimate from primary evidence, with a margin of years.

The translation cannot be dated; the sources say only that Ulfilas made it as bishop. His episcopate is fixed by his pupil Auxentius: he was ordained at thirty, served seven years beyond the Danube and thirty-three on Roman soil, and died at Constantinople, where he had gone at the emperor’s summons (Auxentius, Letter on Ulfilas sections on his ordination and flight) (Auxentius, Letter on Ulfilas sections on his death at Constantinople). The document that quotes Auxentius places that journey under Theodosius I, which puts his death in the early 380s and his ordination forty years earlier. Philostorgius says he was ordained by “Eusebius and the other prelates that were with him” while on an embassy to the emperor, whom the surviving summary names as Constantine (Philostorgius, Church History 2.5).

Scholars give either 341 or 336 for the ordination. T. D. Barnes, “The Consecration of Ulfila”, Journal of Theological Studies 41 (1990), pp. 541–545, reports that most connect it with the council of Antioch in 341 and treat the name Constantine as a slip, and himself argues for the earlier date. The sources are translated and discussed in Peter Heather and John Matthews, The Goths in the Fourth Century (1991), chapter 5. The timeline places the event at the start of his episcopate, at the later of the two dates.
