The Nicene Age
Who Ascholius (Acholius) of Thessalonica was
Bishop of Thessalonica through the five years in which the Nicene settlement was made law, and a figure the archive held twice under two spellings of one name until they were merged in August 2026.
He received the relics of **Sabbas the Goth** from beyond the Danube and forwarded them, with the letter of the church in Gothia, to Basil of Caesarea — which is how that Passion survives at all; he is very likely the recipient named in the covering letter, and possibly its drafter. **He baptised Theodosius I at Thessalonica in 380**, when the emperor fell gravely ill there — days before the edict *Cunctos populos* made the Nicene faith the law of the Roman world. He crossed to the **Council of Constantinople in 381 carrying Damasus's demands**: that Maximus the Cynic be expelled as an interloper, and that bishops not be translated between sees — the second of which was used against Gregory of Nazianzus, who resigned. Basil's letters court him as the hope of Illyricum; Ambrose preached his memorial.
**The name is spelled both ways in the sources** — Ἀχόλιος in the Greek, Acholius in Ambrose and the Latin west, Ascholius in Basil's letter headings and in the Gothic dossier. The archive records the variant rather than choosing silently between two men who are one.
