St. Ambrose (430 A.D.) wrote, ". . . Mary, a Virgin not only undefiled but a virgin whom grace has made inviolate, free of every stain."
Concerning Blessed Mary, St. Augustine wrote, "I wish to have absolutely no question when treating of sin."
St. Ephraem, in a poem addressed to Christ, wrote "Thou and thy mother are alone in this—you are wholly beautiful in every respect. There is in thee, Lord, no stain, nor any spot in thy Mother."
In praise of Mary, he also wrote, "My Lady most holy, all-pure, all-immaculate, all-stainless, all-undefiled, all-incorrupt, all-inviolate . . . spotless robe of Him who clothes himself with light as with a garment . . . flower unfading, purple woven by God, alone most immaculate!"
