The Nicene Age
Who Theodorus (bishop at Aquileia) was
One of the thirty-two Western bishops who sat at Aquileia on 3 September 381 and deposed the Homoian bishops Palladius of Ratiaria and Secundianus of Singidunum. The acts survive as verbatim stenographic minutes — the only fourth-century council that can be read as recorded dialogue rather than as canons and a letter — so his presence is documented to the day.
Named once, in the roll of the Council of Aquileia (3 September 381); no other ancient source names him.
Also listed in bishops beyond the great sees.
