John Chrysostom
Catena Aurea · Lukasevangelium 3
Now when all the people were baptized, it came to pass, that Jesus also being baptized, and praying, the heaven was opened, And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.
Christ indeed had already manifested Himself at His birth by many oracles, but because men would not consult them, He who had in the mean time remained secret, again more clearly revealed Himself in a second birth. For formerly a star in the heavens, now the Father at the waves of Jordan declared Him, and as the Spirit descended upon Him, pouring forth that voice over the head of Him who was baptized, as it follows, And a voice came from heaven, Thou art my beloved Son.
