All Commentaries on Luke 3:21 Go To Luke 3
Ambrose of Milan
AD 397
We saw the Spirit, but in bodily form, let us also see the Father. Because we cannot see, let us hear. Our merciful God is present. He will not forsake his temple. He wishes to build up every soul, he wishes to mold it for salvation, he wishes to convey living stones from earth to heaven. He loves his temple. Let us love him. If we love God, let us keep his commandments. If we love him, we shall know him. He who says that he knows him and keeps not his commandments is a liar. For how can he who does not love Truth love God, for God is Truth? Therefore let us hear the Father, for the Father is invisible. Yet the Son is invisible according to his divinity, for no one has seen God at any time. So, while the Son is God, he is not seen as the Son, insofar as he is God. Yet he wished to show himself in the body. Because the Father did not wear a body, therefore the Father wished to prove to us that he is present in the Son, saying, “You are my beloved Son. In you I am well pleased.” If you wish to learn that the Son is always present with the Father, read the voice of the Son saying, “If I go up into heaven, you are there. If I go down into the grave, you are present there.” If you seek evidence of the Father, you have heard it from John. Believe him by whom Christ believed he must be baptized, to whom the Father entrusted his Son, saying with a heavenly voice, “This is my beloved Son, in whom I am well pleased.”
