685. From what has been said now and heretofore it can be seen that the three uses of baptism cohere as a unit, like first cause, mediate cause, which is the efficient cause, and last cause, which is the effect and the end itself, for the sake of which the former exist; for the first use is that the man may be called a Christian; the second, following from this, is that he may know and acknowledge the Lord the Redeemer, Regenerator and Savior; and the third that be may be regenerated by Him; and when this is done man is redeemed and saved. As these three uses follow in order, and are conjoined in the last, and consequently in the conception of the angels cohere as a unit, so when baptism is performed, read of in the Word, or mentioned, the angels who are present do not understand baptism, but regeneration. Therefore, by these words of the Lord:
He that believeth and is baptized shall be saved, but he that believeth not shall be condemned (Mark 16:16);
the angels in heaven understand that he who acknowledges the Lord and is regenerated will be saved. And for this reason baptism is called by the Christian churches on earth the laver of regeneration. Let every Christian know, then, that he who does not believe in the Lord even though he has been baptized, cannot be regenerated. Also that baptism without faith in the Lord has no effect whatever, may be seen above, in the second section of this chapter (n. 673). Every Christian is well aware that baptism involves purification from evils, and thus regeneration, for when he is baptized in infancy, the priest with his finger makes the sign of the cross, as a memorial of the Lord, on his forehead and breast, and afterwards turns to his sponsors and asks whether he renounces the devil and all his works, and accepts the faith; to which the sponsors, in the place of the infant, answer, "Yes." The renunciation of the devil, that is, of the evils that are from hell, and faith in the Lord, are what effect regeneration.
