The holy Virgin Mary was born of her aged parents, Joachim and Anna. Her father was of the tribe of David and her mother of the tribe of Aaron, and so she was of royal blood from her father and priestly blood from her mother. By this, she foreshadowed Him who would be born of her as King and High Priest. Her parents were already old and had no children, and, because of this, were ashamed before men and humble before God. In their humility, they prayed with tears that God would bring joy to their old age with the gift of a child, as He had once given joy to the aged Abraham and Sarah, giving them their son Isaac. God, almighty and all-seeing, gave them a joy far exceeding all their expectations and their wildest dreams, for He gave them not just a daughter, but the Mother of God; He illumined them not only with temporal joy but with eternal. God gave them just one daughter, who later gave them just one grandson - but what a daughter and what a grandson! Mary full of grace, blessed among women, the temple of the Holy Spirit, altar of the living God, table of living bread, ark of God"s holy things, tree of the most delicious fruits, glory of the human race, praise of womanhood, fount of virginity and purity - this was the daughter given by God to Joachim and Anna. Born in Nazareth, she was after three years taken to the Temple in Jerusalem, whence she returned again to Nazareth and shortly afterwards heard the tidings of the holy Archangel Gabriel concerning the birth of the Son of God, the Saviour of the world, from her most pure and virginal body.
