"What need have I of that other baptism, who have been baptized with the Holy Spirit?"

"For Isaiah did not send you to a bath, there to wash away murder and other sins, which not even all the water of the sea were sufficient to purge; but, as might have been expected, this was that saving bath of the olden time which followed those who repented, and who no longer were purified by the blood of goats and of sheep, or by the ashes of an heifer, or by the offerings of fine flour, but by faith through the blood of Christ …

By reason, therefore, of this laver of repentance and knowledge of God, which has been ordained on account of the transgression of God’s people, as Isaiah cries, we have believed, and testify that that very baptism which he announced is alone able to purify those who have repented; and this is the water of life. But the cisterns which you have dug for yourselves are broken and profitless to you. For what is the use of that baptism which cleanses the flesh and body alone? Baptize the soul from wrath and from covetousness, from envy, and from hatred; and, lo! the body is pure. For this is the symbolic significance of unleavened bread, that you do not commit the old deeds of wicked leaven. But you have understood all things in a carnal sense, and you suppose it to be piety if you do such things, while your souls are filled with deceit, and, in short, with every wickedness. … Let the wicked forsake his ways, and the unrighteous man his thoughts; and let him return unto the Lord, and he will obtain mercy, because He will abundantly pardon your sins. … What need, then, have I of circumcision, who have been witnessed to by God? What need have I of that other baptism, who have been baptized with the Holy Spirit?”
