Catena Aurea on John 2:23–25: Augustine of Hippo

What meaneth this, Many believed in His Name—but Jesus did not commit Himself unto them? Was it that they did not believe in Him, but only pretended that they did? In that case the Evangelist would not have said, Many believed in His Name. Wonderful this, and strange, that men should trust Christ, and Christ trusts not Himself to men; especially considering that He was the Son of God, and suffered voluntarily, or else need not have suffered at all. Yet such are all catechumens. If we say to a catechumen, Believest thou in Christ? he answers, I do believe, and crosses himself. If we ask him, Dost thou eat the flesh of the Son of man? he knows not what we sayk, for Jesus has not committed Himself to him.
