v. 30 — This is He of Whom I said.

He leads the hearers to remembrance of his words, and yields to Christ the superiority in glory, accomplishing the work, not of love, but rather of truth and necessity. For the creature is subject, even if it willeth not, to the Creator? the bond to the Lord, the supplied to the Giver. But in what manner Christ was after John, but preferred before him, for He was before him, as himself confesseth, we have spoken sufficiently in what has preceded.
