Ambrose of Milan : The Synagogue has not this oil, inasmuch as she has not the olive, and understood not that dove which brought back the olive branch after the deluge. For that Dove descended afterwards when Christ was baptized, and abode upon Him, as John testified in the Gospel, saying: "I saw the Spirit descending from heaven like a dove, and He abode upon Him." But how could he see the Dove, who saw not Him, upon Whom the Spirit descended like a dove? — Letter 41.21 Augustine of Hippo : The secular powers often and for a long time spare the wicked from corporal punishment and relieve some of them from their harassments, but the hearts of holy men never have any respite until the end of the world from the sinful conduct of men. It is thus we have the fulfillment of what the apostle said, as I cited it, that "all who will live godly in Christ suffer persecution." Their suffering is more bitter in proportion to its inwardness. This is so until a man passes over the deluge where the ark shelters the raven and the dove. — LETTERS 248 Augustine of Hippo : It is not difficult to see why everlasting peace is signified by the olive branch that the dove, returning, brought back to the ark. For we know that the smooth surface of oil is not readily hindered by a different liquid. And the olive tree itself is forever in leaf. — CHRISTIAN INSTRUCTION 2.16.24 Bede : But after waiting another seven days, he again sent the dove out of the ark; and it came back to him in the evening, carrying a fresh olive branch in its mouth. For the olive branch found outside and brought into the ark by the dove signifies those who receive baptism outside the Church but are fruitful in the richness of charity and, with a pious intention, are upright like the greenness of leaves: many of whom, later on, as if at evening, are called back to the Church by the reconciliation of spiritual men, just as the dove did well after the seven days when it did not find rest outside itself. For the number seven of days is mystically adapted to the light of spiritual grace because, after spiritual men withdraw their minds from carnal desires, they strive to withdraw others as well, guided by the same spirit of grace. It may also be understood that in the dove, which brought the olive branch into the ark after the window was opened after the flood, this is prefigured: that, when the Lord was baptized in the Jordan, the heavens were opened, and the Holy Spirit descended in the form of a dove upon Him; that, upon each individual receiving baptism as a child of the Church, the hand of the bishop is laid upon them through the anointing of the sacred chrism to open to them the gate of the heavenly kingdom, so that they receive the Holy Spirit. To this figure aptly corresponds the raven that had gone out before the dove brought in the olive branch and did not return to the ark, lest prophecy should pass over in silence or Simon's unbelief, who was indeed baptized in the Church but, before receiving the grace of the Holy Spirit through the laying on of hands, was cast out from the Church because, filled with the gall of bitterness, he bore not the innocence of dove-like simplicity but the raven's blackness in his wicked heart. — Commentary on Genesis (Hexaemeron) Bede : After [the raven] he sent a dove, and it came to him in the evening, carrying in its mouth an olive branch with green leaves. You are paying attention, I believe, and with your intellect you anticipate me as I speak. The olive branch with green leaves is the grace of the Holy Spirit, rich in the words of life, the fullness of which rests upon Christ, [as] the psalm says, "God, your God, has anointed you with the oil of gladness above your fellows." Concerning this gift given to Christ's fellows, John speaks: "You have the anointing from the holy one, and you know all things." And by a most beautiful conjunction the figure is in agreement with the fulfillment—a corporeal dove brought the olive branch to the ark which was washed by the waters of the flood; the Holy Spirit descended in the form of a corporeal dove upon the Lord when he was baptized in the waters of the Jordan. Not only the human beings but also the living things which the ark contained, and also the very wood from which the ark was made, prefigure us members of Christ and of the church after our reception of the washing of the waters of regeneration. Through the anointing of the sacred chrism may we be signed with the grace of the Holy Spirit, and may he deign to keep it inviolate in us who himself gave it [to us], Jesus Christ our Lord who with the almighty Father in the unity of the same Holy Spirit lives and reigns for all ages. Amen. — Homilies on the Gospels, HOMILY XI. ON THE FEAST DAY OF THEOPHANY
