Maybe not totally about Baptism, but it does reveal something about his thinking on baptism.
This is the meaning of, the Spirit gives life. The former makes its captive dead from being alive, the latter renders the man it has convicted alive from being dead. For, come unto me, you that labor and are heavy laden, (Matt. xi. 28.) and, He said not, ‘I will punish you,’ but, I will give you rest. For in Baptism the sins are buried, the former things are blotted out, the man is made alive, the entire grace written upon his heart as it were a table. – St. John Chrysostom on 2 Cor. 3
