Annunciation of the Theotokos
The Virgin Mary is the Theotokos, the mother of Jesus Christ, the Son and Word of God. She conceived by the power of the Holy Spirit. She was cared for by her betrothed husband, Joseph, who took the child and his mother into his home as his own. One very strong tradition in the Orthodox Church holds that the birth of Jesus was also miraculous and left Mary's virginity intact as a sign; it is also the tradition of the Church that Joseph and Mary did not have relations after the birth of Jesus. She is also called Panagia, the "All-Holy," indicating her closeness to God in her obedience. The title Theotokos (in Greek, Θεοτόκος) is a Greek word that means "God-bearer" or "Birth-giver to God."
Reading
Six months after John the Forerunner's conception, the Archangel Gabriel was sent by God to Nazareth, a town of Galilee, unto Mary the Virgin, who had come forth from the Temple a mature maiden (see Nov. 21). According to the tradition handed down by the Fathers, she had been betrothed to Joseph four months. On coming to Joseph's house, the Archangel declared: "Rejoice, thou Full of Grace, the Lord is with thee: blessed art thou among women." After some consideration, and turmoil of soul, and fear because of this greeting, the Virgin, when she had finally obtained full assurance concerning God's unsearchable condescension and the ineffable dispensation that was to take place through her, and believing that all things are possible to the Most High, answered in humility: "Behold the handmaid of the Lord; be it unto me according to thy word." And at this, the Holy Spirit came upon her, and the power of the Most High overshadowed her all-blameless womb, and the Son and Word of God, Who existed before the ages, was conceived past speech and understanding, and became flesh in her immaculate body (Luke 1:26-38).
Bearing in her womb the Uncontainable One, the blessed Virgin went with haste from Nazareth to the hill country of Judea, where Zacharias had his dwelling; for she desired to find Elizabeth her kinswoman and rejoice together with her, because, as she had learned from the Archangel, Elizabeth had conceived in her old age. Furthermore, she wished to tell her of the great things that the Mighty One had been well-pleased to bring to pass in her, and she greeted Elizabeth and drew nigh to her. When Elizabeth heard Mary's greeting, she felt her six-month-old babe, Saint John the Baptist, prophesied of the dawning of the spiritual Sun. Immediately, the aged Elizabeth was filled with the Holy Spirit and recognized her as the Mother of her Lord, and with a great voice blessed her and the Fruit that she held within herself. The Virgin also, moved by a supernatural rejoicing in the spirit, glorified her God and Savior, saying: "My soul doth magnify the Lord, and my spirit hath rejoiced in God my Saviour," and the rest, as the divine Luke hath recorded (1:39-55). The annual celebration of the Annunciation is on March 25th.
