Feast of the Annunciation

From the readings at Matins:

Reading 4 (From Sermon 22 of Pope St Leo the Great): The Almighty and merciful God, Whose nature is goodness, Whose will is power, and Whose work is mercy, did, at the very beginning of the world, as soon as the devil's hatred had mortally poisoned us with the venom of his envy, foretell those remedies which His mercy had foreordained for our healing. He bade the serpent know that there was to be a Seed of the woman Who should yet bruise the swelling of his pestilential head; this Seed was none other than the Christ to come in the flesh, that God and Man in one Person, Who, being born of a Virgin, should, by His undefiled birth, damn the seducer of man.

Reading 6: The devil rejoiced that by his fraud he had so deceived man as to make him lose the gifts of God, forfeit his privilege of eternal life, bring himself under the hard sentence of death, and find in his misery a certain comfort in the accomplice of his guilt; he rejoiced also that God, in His just anger, was changed towards man, whom He had made in such honour. But, dearly beloved brethren, that Unchangeable God, Whose Will cannot be divorced from His goodness, by His own secret counsel carried out in a mysterious way His original purpose of goodness, and man, who had been led into sin by the wicked craft of the devil, perished not to disappoint that gracious purpose of God.

Reading 7: Then therefore, dearly beloved brethren, the fullness of that time came, which God had appointed for our Redemption, our Lord Jesus Christ entered this lower world, came down from His heavenly throne, and, while He left not that glory which He hath with the Father before the world was, was incarnate by a new order and a new birth new, in that He Who is Invisible among His own, was made visible among us; He Who is Incomprehensible, willed to be comprehended; He Who is before the ages, began to be in time; the Lord of all shadowed the glory of His Majesty, and took upon Him the form of a servant; the Impassible God vouchsafed to become a man subject to suffering; and the Immortal laid Himself under the laws of death.

Reading 8: For though the true mercy of God had infinitely many schemes to hand for the restoration of mankind, it chose that particular design which put in force for destroying the devil's work, not the efficacy of might but the dictates of justice. For the pride of the ancient foe not undeservedly made good its despotic rights over all men, and with no unwarrantable supremacy tyrannized over those who had been of their own accord lured away from God's commands to be the slaves of his will.And so there would be no justice in his losing the immemorial slavery of the human race, were he not conquered by that which he had subjugated.
