God could have given us the Redeemer of the human race, and the Founder of the Faiths in another way than through the Virgin, but since Divine Providence has been pleased that we should have the Man-God through Mary, who conceived Him by the Holy Spirit and bore Him in her womb, it only remains for us to receive Christ from the hands of Mary.
