Cyprian of Carthage
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.
(De unit. Eccles.) the dove is a harmless and pleasant creature, with no bitterness of gall, no fierceness of bite, no violence of rending talons; they love the abodes of men, consort within one home, when they have young nurturing them together, when they fly abroad, hanging side by side upon the wing, leading their life in mutual intercourse, giving with their bills a sign of their peaceful harmony, and fulfilling a law of unanimity in every way.
