Excerpt from St. Gregory Palamas’ Homily on the Annunciation from Mary the Mother of God, pp. 56 & 58-59
Continuing as you are now with your virginity inviolate, you shall conceive a child and bear the Son of the Highest. Isaiah foresaw this many years before and prophesied, “Behold, a virgin shall conceive, and bear a son”, and, “I went unto the prophetess”. In what way did the Prophet go to the Prophetess? In the same way the Archangel now came to her. What the Archangel now saw, the Prophet foresaw and foretold. That the Virgin was a prophetess with the gift of prophecy, is proved to all by her hymn to God in the Gospel (Luke 1:46-55).
…Surely it is obvious to anyone that the Virgin Mother is both the burning bush and the tongs. She conceived the divine fire within her and was not burnt, and an Archangel ministered at the conception, and through her the Bearer of the sins of the world was united with the human race, purifying us thoroughly by means of this indescribable bond. The Virgin Mother, and she alone, is the frontier between created and uncreated nature. All who know God will recognize her as the one who contained Him Who cannot be contained. All who sing hymns to God will praise her next after Him. She is the cause of the benefits which preceded her, the protectress of those which came after and through her those good things which are eternal shall be received. She is the theme of the prophets, the first of the Apostles, the support of martyrs, the dais of the teachers. She is the glory of those on earth, the delight of those in heaven, the adornment of the whole Creation. She is the beginning, fount and root of the hope store up for us in heaven.
To which may we all obtain her prayers for us, to the glory of Him Who was begotten of the Father before all ages, and, in these last times, became incarnate of her, even Jesus Christ Our Lord. To Whom belong all glory, honour and worship, now and for ever and unto the ages of ages. Amen.
