Augustine of Hippoc. 413
A Treatise on the Origin of the Human Soul, Addressed to Jerome. 1. Unto our God, who has called us unto His kingdom and glory, 1 Thessalonians 2:12 I have prayed, and pray now, that what I write to you, holy brother Jerome, asking your opinion in regard to things of which I am ignorant, may by His good pleasure be profitable to us both.
