the apostle said, "He that eateth unworthily, eateth and drinketh damnation to himself."[311] Let the heretics therefore seek in the Catholic Church not what they have, but what they have not,--that is, the end of the commandment, without which many holy things may be possessed, but they cannot profit. "Now, the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned."[312] Let them therefore hasten to the unity and truth of the Catholic Church, not that they may have the sacrament of washing, if they have been already bathed in it, although in heresy, but that they may have it to their health. * * * * * CHAP. IX.--10. Now we must see what is said of the baptism of John. For "we read in the Acts of the Apostles, that those who had already been baptized with the baptism of John were yet baptized by Paul,"[313] simply because the baptism of John was not the baptism of Christ, but a baptism allowed by Christ to John, so as to be called especially John's baptism; as the same John says, "A man can receive nothing, except it be given him from heaven."[314] And that he might not possibly seem to receive this from God the Father in such wise as not to receive it from the Son, speaking presently of Christ Himself, he says, "Of His fulness have we all received."[315] But by the grace of a certain dispensation John received this, which was to last not for long, but only long enough to prepare for the Lord the way in which he must needs be the forerunner. And as our Lord was presently to enter on this way with all humility, and to lead those who humbly followed Him to perfection, as He washed the feet of His servants,[316] so was He willing to be baptized with the baptism of a servant.[317] For as He set Himself to minister to the feet of those whose guide He was Himself, so He submitted Himself to the gift of John which He Himself had given, that all might understand what sacrilegious arrogance they would show in despising the baptism which they ought each of them to receive from the Lord, when the Lord Himself accepted what He Himself had bestowed upon a servant, that he might give it as his own; and that when John, than whom no greater had arisen among them that are born of women,[318] bore such testimony to Christ, as to confess that he was not worthy to unloose the latchet of His shoe,[319] Christ might both, by receiving his baptism, be found to be the humblest among men, and, by taking away the place for the baptism of John, be believed to be the most high God, at once the teacher of humility and the giver of exaltation.
