Chapter XXXIX.—Baptism Instituted in Place of Sacrifices.

“But when the time began to draw near that what was wanting in the Mosaic institutions should be supplied, as we have said, and that the Prophet should appear, of whom he had foretold that He should warn them by the mercy of God to cease from sacrificing; lest haply they might suppose that on the cessation of sacrifice there was no remission of sins for them, He instituted baptism by water amongst them, in which they might be absolved from all their sins on the invocation of His name, and for the future, following a perfect life, might abide in immortality, being purified not by the blood of beasts, but by the purification of the Wisdom of God.  Subsequently also an evident proof of this great mystery is supplied in the fact, that every one who, believing in this Prophet who had been foretold by Moses, is baptized in His name, shall be kept unhurt from the destruction of war which impends over the unbelieving nation, and the place itself; but that those who do not believe shall be made exiles from their place and kingdom, that even against their will they may understand and obey the will of God.”
