Acts 22:16

But when he saith, Wash away thy sins, by this speech he expresseth the force and fruit of baptism, as if he had said, Wash away thy sins by baptism. But because it may seem that by this means more is attributed to the outward and corruptible element than is meet, the question is, whether baptism be the cause of our purging. Surely, forasmuch as the blood of Christ is the only means whereby our sins are washed away, and as it was once shed to this end, so the Holy Ghost, by the sprinkling thereof through faith, doth make us clean continually. This honor cannot be translated unto the sign of water, without doing open injury to Christ and the Holy Ghost; and experience doth teach how earnestly men be bent upon this superstition. Therefore, many godly men, lest they put confidence in the outward sign, do overmuch extenuate the force of baptism. But they must keep a measure, that the sacraments may be kept within their bounds, lest they darken the glory of Christ; and yet they may not want their force and use.

Wherefore, we must hold this, first, that it is God alone who washeth us from our sins by the blood of his Son; and to the end this washing may be effectual in us, he worketh by the hidden power of his Spirit. Therefore, when the question is concerning remission of sins, we must seek no other author thereof but the heavenly Father, we must imagine no other material cause but the blood of Christ; and when we be come to the formal cause, the Holy Ghost is the chief. But there is an inferior instrument, and that is the preaching of the word and baptism itself. But though God alone doth work by the inward power of his Spirit, yet that doth not hinder but that he may use, at his pleasure, such instruments and means as he knoweth to be convenient; not that he includeth in the element anything which he taketh either from his Spirit or from the blood of Christ, but because he will have the sign itself to be an help for our infirmity.

Therefore, forasmuch as baptism doth help our faith, that it may reap forgiveness of sins by the blood of Christ alone, it is called the washing of the soul. So that the washing, spoken of by Luke, doth not note out the cause; but is referred unto the understanding of Paul, who, having received the sign, knew better that his sins were done away. Though we must also note this, that there is no bare figure set before us in baptism, but that the giving of the thing is thereto annexed; because God promised nothing deceitfully, but doth, indeed, fulfill that which under the signs he doth signify. Notwithstanding, we must again beware that we tie not the grace of God to the sacraments; for the external administration of baptism profiteth nothing, save only where it pleaseth God it shall. By this there is also another question answered which may be moved. For seeing Paul had the testimony of the grace of God, his sins were already forgiven him. Therefore, he was not washed only by baptism, but he received a new confirmation of the grace which he had gotten.

In calling upon the name of the Lord. It is out of question that he meaneth Christ, not because the name of Christ alone is called upon in baptism, but because the Father commandeth us to ask of him whatsoever is figured in baptism; neither doth the operation of the Spirit tend to any other end, saving that it may make us partakers of his death and resurrection. Therefore, Christ is appointed to excel in baptism, yet inasmuch as he is given us of the Father, and inasmuch as he poureth out his graces upon us by the Holy Ghost. Whereby it cometh to pass that the calling upon the name of Christ containeth both the Father and the Son.

Wherefore, Ananias doth not mean, that the name of Christ must only be named, but he speaketh of prayer, whereby the faithful do testify, that the effect of the outward sign is in the power of Christ alone. For the sacraments have neither any power of salvation included in them, neither are they anything worth of themselves. Wherefore, this member is, as it were, a correction of the former saying, because Ananias doth, in plain words, send Paul from reposing confidence in the external sign unto Christ.

It is well known how much the Papists differ from this rule, who tie the cause of grace to their exorcisms and enchantments; and they are so far from studying to direct the miserable people unto Christ, that they rather drown Christ in baptism, and pollute his sacred name by their enchantments.
