...As Noah, then, obtained life through death, when in the ark, he was enclosed not otherwise than as it were in the grave, and when the whole world perished, he was preserved together with his small family; so at this day, the death which is set forth in baptism, is to us an entrance into life, nor can salvation be hoped for, except we be separated from the world.
Not the putting away of the filth of the flesh. This was added, because it might be that the greatest part of men would profess the name of Christ; and so it is with us, almost all are introduced into the church by baptism. Thus, what he had said before would not be appropriate, that few at this day are saved by baptism, as God saved only eight by the ark. This objection Peter anticipates, when he testifies that he speaks not of the naked sign, but that the effect must also be connected with it, as though he had said, that what happened in the age of Noah would always be the case, that mankind would rush on to their own destruction, but that the Lord would in a wonderful way deliver His very small flock.
We now see what this connection means; for some one might object and say, "Our baptism is widely different from that of Noah, for it happens that most are at this day baptized." To this he replies, that the external symbol is not sufficient, except baptism be received really and effectually: and the reality of it will be found only in a few. It hence follows that we ought carefully to see how men commonly act when we rely on examples, and that we ought not to fear though we may be few in number.
But the fanatics, such as Schuencfeldius, absurdly pervert this testimony, while they seek to take away from sacraments all their power and effect. For Peter did not mean here to teach that Christ's institution is vain and inefficacious, but only to exclude hypocrites from the hope of salvation, who, as far as they can, deprave and corrupt baptism. Moreover, when we speak of sacraments, two things are to be considered, the sign and the thing itself. In baptism the sign is water, but the thing is the washing of the soul by the blood of Christ and the mortifying of the flesh. The institution of Christ includes these two things. Now that the sign appears often inefficacious and fruitless, this happens through the abuse of men, which does not take away the nature of the sacrament. Let us then learn not to tear away the thing signified from the sign. We must at the same time beware of another evil, such as prevails among the Papists; for as they distinguish not as they ought between the thing and the sign, they stop at the outward element, and on that fix their hope of salvation. Therefore the sight of the water takes away their thoughts from the blood of Christ and the power of the Spirit. They do not regard Christ as the only author of all the blessings therein offered to us; they transfer the glory of his death to the water, they tie the secret power of the Spirit to the visible sign.
What then ought we to do? Not to separate what has been joined together by the Lord. We ought to acknowledge in baptism a spiritual washing, we ought to embrace therein the testimony of the remission of sin and the pledge of our renovation, and yet so as to leave to Christ his own honor, and also to the Holy Spirit; so that no part of our salvation should be transferred to the sign. Doubtless when Peter, having mentioned baptism, immediately made this exception, that it is not the putting off of the filth of the flesh, he sufficiently shewed that baptism to some is only the outward act, and that the outward sign of itself avails nothing...
