Augustine of Hippo1979

Variously titled, “Psalm Against the Party of the Donatists,” “Alphabetical Psalm Against the Donatists,” “One Book, a Psalm against the Party of the Donatists,” [2] etc. Latin text in Migne Patrologia Latina (PL) 43:
23-32 [3] "St. Augustine began his victorious campaign against Donatism soon after he was ordained priest in 391. His popular psalm or "Abecedarium" against the Donatists was intended to make known to the people the arguments set forth by St. Optatus, with the same conciliatory end in view. It shows that the sect was founded by traditors, condemned by pope and council, separated from the whole world, a cause of division, violence, and bloodshed;* the true Church is the one Vine, whose branches are over all the earth." - Catholic Encyclopedia [4] * Augustine frequently complained of the Donatist's violence against the Catholics (see e.g. letters 105, 185 209). Even so, he maintained a deep pastoral love and concern for them, [5] and ever strove for their eventual return to "the Unity," one of his "favorite names for the Catholic Church." [6].
