2 God predestined her from all eternity to be the Mother of the Incarnate Word, and for that reason so highly distinguished her among all His most beautiful works in the triple order of nature, grace and glory, that the Church justly applies to her these words: "I came out of the mouth of the Most High, the first-born before all creatures" (Ecclus. xxiv., 5). And when, in the first ages, the parents of mankind fell into sin, involving their posterity in the same ruin, she was set up as a pledge of the restoration of peace and salvation. The Only-begotten Son of God ever paid to His Most Holy Mother indubitable marks of honour. During His private life on earth He associated her with Himself in each of His first two miracles: the miracle of grace, when, at the salutation of Mary, the infant leaped in the womb of Elizabeth; the miracle of nature, when He turned water into wine at the marriage - feast of Cana. And, at the supreme moment of His public life, when sealing the New Testament in His precious Blood, He committed her to his beloved Apostle in those sweet words, "Behold, thy Mother!" (John xix., 27).
