Bede the Venerable
Catena Aurea · Markusevangelium 1
And it came to pass in those days, that Jesus came from Nazareth of Galilee, and was baptized of John in Jordan. And straightway coming up out of the water, he saw the heavens opened, and the Spirit like a dove descending upon him: And there came a voice from heaven, saying, Thou art my beloved Son, in whom I am well pleased.
(ubi sup.) This event also, in which the Holy Ghost was seen to come down upon baptism, was a sign of spiritual grace to be given to us in baptism.
