"Interest in the conception of the Lord was fostered by popular reflection on the Gospel stories, and the liturgical embodiment of this reflection also played a part in the development of reverence for life in the womb. The December 25th feast of the Nativity of the Lord was established by the late fourth century. By the seventh century in the East a feast was established marking the Annunciation to Mary or "the Conception of Christ." This feast was established on March 25, with the implication that nine months had elapsed between conception and birth, and with the further implication that what had come from the Holy Spirit to Mary had been holy from the moment of conception. The feast of the Conception of Christ, it may be supposed, served, beyond its primary meaning, as a symbol of the sacredness of any conception. In the late sixth century there also came into existence in the East the feast of the Nativity of Mary, fixed on September 8. A century later the feast of Mary's conception by St. Anne was established on December 9 with an elaborate vigil on December 8. The prayers in the office of the day rejected the belief that Mary had been "born: after seven months," an apparent repudiation of the view that her soul was infused after her conception. The feast in honor of Christ's conception could be explained as a feast for a conception of a divine man; but the conception of Mary was believed to be the conception of a human being by the inter-course of humans. The recognition that she deserved honor at conception had specific implication for the humanity of all men."
