Illustrious Men (Supplement to Jerome)

Syagrius wrote On faith, against the presumptuous words, which heretics assume for the purpose of destroying or superseding the names of the Holy Trinity, for they say that the Father ought not to be called Father, lest the name, Son should harmonize with that of Father, but that he should be called the Unbegotten or the Imperishable and the Absolute, in order that whatever may be distinct from Him in person, may also be separate in nature, showing that the Father, who is unchangeable in nature may be called the Unbegotten, though the Scripture may not call Him so, that the person of the Son is begotten from Him, not made, and that the person of the Holy Spirit proceeds from Him not begotten, and not made. Under the name of this Syagrius I found seven books, entitled On Faith and the rules of Faith, but as they did not agree in style, I did not believe they were written by him.
