This day is called the Visitation of the Blessed Virgin Mary because on it Mary visited her cousin Elizabeth, whom, as the angel had told her, God had blessed with a son in her old age.
In the Introit of the Mass the Church sings:
"Hail, holy parent, who didst bring trth the King Who rules heaven and earth forever. My heart hath uttered a good word; I speak of my works for the King."
Glory be to the Father, and to the Son, and to the Holy Ghost. As it was in the beginning, is now, and ever shall be, world without end. Amen.
