Augustine of Hippo, on Matt 7:15

“Beware of false prophets, who come to you in the clothing of sheep, but inwardly they are ravening wolves.”

“(Serm. in Mont. ii. 25.) In this place we must guard against the error of such as imagine that the two trees refer to two different natures; the one of God, the other not. But we affirm that they derive no countenance from these two trees; (Manichees, vid. infr.) as it will be evident to any who will read the context that He is speaking here of men.”
