This is the Feast of the Annunciation to the Blessed Virgin Mary. And so we honor her today - and every day - with the words of the Archangel, "Hail Mary, full of grace!" But let us not forget that this is the day of the Incarnation, the day that marked the beginning of all things being made right again by the Holy God:
Today are strains of praise sung joyfully by the choir of angels, and the light of the advent of Christ shines brightly upon the faithful.
Today is the glad springtime to us, and Christ the Sun of righteousness has beamed with clear light around us, and has illumined the minds of the faithful.
Today is Adam made anew, and moves in the choir of angels, having winged his way to heaven.
Today is the whole circle of the earth filled with joy, since the sojourn of the Holy Spirit has been realized to men.
Today the grace of God and the hope of the unseen shine through all wonders transcending imagination, and make the mystery that was kept hid from eternity plainly discernable to us.
Today are woven the chaplets of never-fading virtue.
Today, God, willing to crown the sacred heads of those whose pleasure is to hearken to Him, and who delight in His festivals, invites the lovers of unswerving faith as His called and His heirs; and the heavenly kingdom is urgent to summon those who mind celestial things to join the divine service of the incorporeal choirs.
Today is fulfilled the word of David, "Let the heavens rejoice, and let the earth be glad. The fields shall be joyful, and all the trees of the wood before the Lord, because He cometh." David thus made mention of the trees; and the Lord's forerunner also spoke of them as trees "that should bring forth fruits meet for repentance," or rather for the coming of the Lord. But our Lord Jesus Christ promises perpetual gladness to all those who believe on Him. For He says, "I will see you, and ye shall rejoice; and your joy no man taketh from you."
Today is the illustrious and ineffable mystery of Christians, who have willingly set their hope like a seal upon Christ, plainly declared to us.
