When Mary reached the age of three, her parents fulfilled their vow. Together with their family and friends, they took her to the Temple. The High Priest and other Temple priests greeted the procession, and tradition says that the child was brought before the fifteen high steps which led to the sanctuary. It is said that the child Mary made her way to the stairs and, strengthened by the Holy Spirit, ascended all fifteen steps, coming to the Holy of Holies where only the High Priest could enter. Tradition then says that the High Priest, acting outside every rule he knew, led the Holy Virgin into the Holy of Holies, astonishing everyone present in the Temple. So it was that she, whose own womb would become the Holy of Holies, came into the presence of the God Whom she would bear.
St. Joachim and St. Anne returned to their home, but the Handmaid of the Lord remained in the Temple until her espousal, where she was prepared by God. As the grandparents of our Saviour Jesus Christ, they serve as examples and intercessors for all parents and grandparents.
O God, who didst choose blessed Joachim and holy Anne that of them might be born the Mother of thine Only Begotten Son: grant unto us, at their intercession, a place in the fellowship of thine elect, wherein for ever to praise thee for thy lovingkindness; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
