St. Anselm says, “that when we say that Mary is the Mother of God, we speak of a dignity which is above every other dignity that can be named or thought of, after that of God;” therefore he says, “O Lady, nothing equals thee; for all is either above thee, and this is God alone, or beneath thee, and this is all that is not God.” In fine, St. Bernardine writes, “that God alone can know the greatness of Mary.” Saint Albert the Great says, “that Mary could not be more closely united to God without becoming God.” This great Mother of God is, then, indeed worthy of our veneration, since God Himself could not have made her greater than he did when he made her his Mother.
O Mother of God, my Mother Mary, I venerate thee, and would wish thee to be venerated by all hearts, as the exalted Lady that thou art. Pity a poor sinner who loves thee, and trusts in thee. “Virgin most venerable, pray for us.”
