There are three parts, so to say, of adoption which are further distinctly contained in the Divine Sacrifice. The first of these is the derivation of spiritual life from the Person of Christ; for here especially is fulfilled what He said of Himself, "The Bread of God is that which cometh down from heaven and giveth life to the world." In the act of sacrifice He becomes also the food of His brethren: here He was from the beginning daily; here He is to the end. This is the inmost junction of life with belief, so that the faithful people by its presence attesting belief in the Divine Unity and Trinity, in the Incarnation of the Son of God, in His redemption of the race, in the adoption of man by God, at the same time become partakers of the life which these doctrines declare. The perfection of the divine institution consists in this absolute blending of belief, worship, and practice. The unbelieving Jews strove among themselves, saying, "How can this Man give us His flesh to eat?" Our Lord answered by establishing a rite on which His Church lives through all the ages, in which He bestows Himself on each believer individually, being as much his as if He was for him alone. Space and time disappear before the Author of life in the act of communicating Himself, and He is the sole Teacher of His Church, in that He alone feeds it with the Divine Food, which is Himself. But this food is the source of sanctification: as that by which man fell away from God was sin, so that which unites him to God is holiness. It is from the Incarnate Son in the act of sacrifice that this holiness emanates to His people; and the gift of His flesh, the banquet at the sacrifice, dispenses it. No teaching of words could so identify the Person of our Lord with the source of holiness as the bodily act of receiving His flesh. It is the command, "Be ye holy, for I am holy," expressed in action. This is the perennial fountain of holiness which wells forth in the midst of His Church; and beside it, as subordinate and preparatory, is the perpetual tribunal of penance: one and the other given to meet and efface the perpetual frailties of daily life, first to restore the fallen, and then to join them afresh with the source of holiness. There is yet another gift consequent upon adoption, which completes as it were the two we have just mentioned. It is that the flesh of our Lord given in the Blessed Sacrament is the pledge and earnest of eternal life. This He has Himself said in the words, "He that eateth My Flesh and drinketh My Blood hath everlasting life, and I will raise him up at the last day." And St. Thomas, in the beautiful conclusion to the grandest of hymns, has summed up numberless comments of the Fathers on these divine words, where he sings—
