For Christ hath given nothing sensible, but though in things sensible yet all to be perceived by the mind. So also in baptism, the gift is bestowed by a sensible thing, that is, by water; but that which is done is perceived by the mind, the birth, I mean, and the renewal. For if thou hadst been incorporeal, He would have delivered thee the incorporeal gifts bare; but because the soul hath been locked up in a body, He delivers thee the things that the mind perceives, in things sensible.
