In that hour Jesus rejoiced in spirit, and said,
I thank you, O Father, Lord of heaven and earth, that you have hid these things from the wise and prudent, and have revealed them unto babes: even so, Father; for so it seemed good in your sight.
All Commentaries on Luke 10:21 Go To Luke 10
John Chrysostom
AD 407
The proof that the Son knows the Father perfectly rests on the fact that he is “the one who is from God.” The Son has clear knowledge of the Father, because he is from God. The fact that he is from God is a sign and indication that he knows him clearly. An inferior essence would not be able to have clear knowledge of a superior essence, even if the difference between them were slight.
