Now, if you would witness against these unchristian opinions, if you would bring out distinctly and beyond mistake and evasion, the simple idea of the Catholic Church that God is man, could you do it better than by laying down in St. John's words that "God became man"? and again could you express this more emphatically and unequivocally than by declaring that He was born a man, or that He had a Mother? The world allows that God is man; the admission costs it little, for God is everywhere, and (as it may say) is everything; but it shrinks from confessing that God is the Son of Mary. It shrinks, for it is at once confronted with a severe fact, which violates and shatters its own unbelieving view of things; the revealed doctrine forthwith takes its true shape, and receives an historical reality; and the Almighty is introduced into His own world at a certain time and in a definite way. Dreams are broken and shadows depart; the Divine truth is no longer a poetical expression, or a devotional exaggeration, or a mystical economy, or a mythical representation. "Sacrifice and offering," the shadows of the Law, "Thou wouldest not, but a body hast Thou fitted to me." "That which was from the beginning, which we have heard, which we have seen with our eyes, which we have diligently looked upon, and our hands have handled," "That which we have seen and have heard, declare we unto you";—such is the record of the Apostle, in opposition to those "spirits" which denied that "Jesus Christ had appeared in the flesh," and which "dissolved" Him by denying either His human nature or His divine. And the confession that Mary is Deipara, or the Mother of God, is that safeguard wherewith we seal up and secure the doctrine of the Apostle from all evasion, and that test whereby we detect all the pretences of those bad spirits of "Antichrist which have gone out into the world".
