"[...]there is certainly need of some manifest proof, by which we may recognize the new-born man, discerning by clear tokens the new from the old."

"[...]there is certainly need of some manifest proof, by which we may recognize the new-born man, discerning by clear tokens the new from the old. And these I think are to be found in the intentional motions of the soul, whereby it separates itself from its old customary life, and enters on a newer way of conversation, and will clearly teach those acquainted with it that it has become something different from its former self, bearing in it no token by which the old self was recognized. This, if you be persuaded by me, and keep my words as a law, is the mode of transformation. The man that was before Baptism was wanton, covetous, grasping at the goods of others, a reviler, a liar, a slanderer and all the is kindred with these things, and consequent from them. Let him now become orderly, sober, content with his own possesions, and imparting from them to those in poverty, truthful, courteous, affable-in a word, following every laudable course of conduct. For as darkness is dispelled by light, and black disappears as whiteness is spread over it, so the old man also disappears when adorned with the works of righteousness." (On the Baptism of Christ, NPNF, p. 523)
