Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did.

Augustine of Hippo
AD 430
What means this, Many believed in His Name but Jesus did not commit Himself to 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 tomen; 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, Believe you in Christ? he answers, I do believe, and crosses himself. If we ask him, Do you eat the flesh of the Son of man? he knows not what we say for Jesus has not committed Himself to him.
The Maker knew better what was in His own work, than the work knew what was in itself. Peter knew not what was in himself when he said, I will go with You to death; but our Lord’s answer showed that He knew what was in man; Before the cock crow, you shall thrice deny Me.
