The Nativity of the Holy Virgin Mary
When the time drew near for the birth of the Saviour of the world, in the Galilean city of Nazareth, there lived a descendant of King David, Joachim, with his wife Anna. They were both pious people and were known not for their royal ancestry but for their humility and charity.
Their entire lives were permeated with love for God and people. They lived to a ripe old age but never had children, and this grieved them very much. In spite of their old age, they did not cease to petition God to send them children. They made a vow that, if a child was born to them, they would have consecrated it to the service of God. At that time, every Jew hoped that his posterity would have taken a part in the kingdom of the Messiah, that is, Christ the Saviour. Therefore, every childless Jew was held in contempt by the others, for this was considered a great punishment by God for one’s sins. This was especially trying to Joachim as a descendant of King David because from his seed Christ meant to be born.
For their patience, great faith, and love for God and for each other, God sent Joachim and Anna great joy. Toward the end of their lives, a daughter was born to them. According to the command of an angel of God, She was given the name Mary. The birth of Mary brought a joy not only to Her parents but to all people because She was foreordained by God to be the Mother of the Son of God, the Saviour of the world. The Nativity of the Holy Virgin Mary is celebrated by the Holy Orthodox Church as one of its major holidays on the 8th of September.
