John 3:5–8

Verse 5. Unless a man be born again of water, and the Holy Ghost. Though the word Holy be now wanting in all Greek copies, it is certainly the sense. The ancient Fathers, and particularly Saint Augustine in divers places, from these words, prove the necessity of giving baptism to infants: and by Christ’s adding water, is excluded a metaphorical baptism. See also Acts 8:36 and 10:47 and Titus 3:5. Witham.—Except a man be born again. That is, unless you are born again by a spiritual regeneration in God, all the knowledge which you learn from me, will not be spiritual but carnal. But I say to you, that neither you nor any other person, unless you be born again in God, can undestand or conceive the glory which is in me. Saint John Chrysostom

Verse 8. The Spirit breatheth where he will. The Prot. translation has the wind: and so it is expounded by Saint John Chrysostom and S. Cyril on this verse; as if Christ compared the motions of the Holy Ghost to the wind, of which men can give so little account, whence it comes, or whither it goes. Yet many others, as Saint Augustine Saint Ambrose Saint Gregory understand this expression of the Holy Ghost, of whom it can only be properly said, that he breatheth where he will. Witham.

The same Greek word (πνεῦμα) means wind, breath, and spirit.
