The gospel has the doctrine of repentance joined with it: for so said the Lord in the gospel, "In my name must repentance and remission of sins be preached among all nations" (Luke 24:47). By repentance we understand the change of the mind in a sinful man, stirred up by the preaching of the gospel through the Holy Spirit and received by a true faith; by which a sinful man acknowledges his natural corruption and all his sins, convinced of them by the Word of God, and is heartily grieved for them, and not only bewails and freely confesses them before God with shame, but also loathes and abhors them with indignation, thinking seriously of present amendment and of a continual concern for innocence and virtue, wherein to exercise himself in a holy manner all the rest of his life.
And surely this is true repentance, namely, an unfeigned turning unto God and to all goodness, and a serious return from the devil and from all evil. Now we expressly say that this repentance is the mere gift of God, and not the work of our own strength. For the apostle wishes the faithful minister diligently to "instruct those which withstand the truth, if so be at any time the Lord may give them repentance, that they may acknowledge the truth" (2 Tim. 2:25). Also, the sinful woman in the gospel, which washed Christ's feet with her tears; and Peter, which bitterly wept and bewailed his denial of his Master; manifestly show what mind the penitent man should have, to wit, very earnestly lamenting his sins committed. Moreover, the prodigal son, and the publican in the gospel, that are compared with the Pharisee, set forth unto us a most fit pattern of confessing our sins to God. The prodigal son said, "Father, I have sinned against heaven, and against thee: I am not worthy to be called thy son, make me as one of thy hired servants" (Luke 15:18–19). The publican also, not daring to lift up his eyes to heaven, but knocking his breast, cried, "God, be merciful unto me a sinner" (Luke 18:13). And we doubt not but the Lord received them to mercy. For John the apostle says, "If we confess our sins, He is faithful and just to forgive us our sins, and to purge us from all iniquity. If we say we have not sinned, we make Him a liar, and His word is not in us" (1 John 1:9–10).
We believe that this sincere confession which is made to God alone, either privately between God and the sinner, or openly in the church, where that general confession of sins is rehearsed, is sufficient, and that it is not necessary for the obtaining of remission of sins that any man should confess his sins unto the priest, whispering them into his ears, that, the priest laying his hands on his head, he might receive absolution; because we find no commandment nor example thereof in the Holy Scripture. David protests and says, "I made my fault known to thee, and my unrighteousness did I not hide from thee. I said, I will confess my wickedness to the Lord against myself, and thou hast forgiven the heinousness of my sin" (Ps. 32:5). Yes, and the Lord teaching us to pray, and also to confess our sins, said, "So shall ye pray; Our Father, which art in heaven, forgive us our debts, even as we forgive our debtors" (Matt. 6:9, 12). It is requisite, therefore that we should confess our sins unto God, and be reconciled with our neighbor, if we have offended him. And the apostle James speaking generally of confession says, "Confess each of you your sins one to another" (James 5:16). If any man, being overwhelmed with the burden of his sins and troublesome temptations, will privately ask counsel, instruction, or comfort, either of a minister of the church, or of any other brother that is learned in the law of God, we do not dislike it. Also we fully allow that general and public confession, which is wont to be rehearsed in the church, and in holy meetings (whereof we spoke before) being, as it is, agreeable with the Scripture.
Concerning the keys of the kingdom of heaven which the Lord committed to His apostles, they prate many strange things: and of these keys they make swords, spears, scepters, and crowns, and full power over mighty kingdoms, yes, and over men's souls and bodies. But we, judging uprightly according to the Word of God, say that all ministers, truly called, have and exercise the keys or the use of them, when they preach the gospel, that is to say, when they teach, exhort, reprove, and keep in order the people committed to their charge. For so do they open the kingdom of God to the obedient, and shut it against the disobedient. These keys did the Lord promise to the apostles in Matthew 16:19; and delivered them in John 20:23, Mark 16:15–16 and Luke 24:47 when He sent forth His disciples, and commanded them to preach the gospel in all the world, and to remit sins.
The apostle in the epistle to the Corinthians says that the Lord "gave to His ministers the ministry of reconciliation" (2 Cor. 5:18). And what this was, he straightway makes plain and says, "The word or doctrine of reconciliation" (v. 19). And yet more plainly expounding his words, he adds that the ministers of Christ, as it were, "go an embassage in Christ's name, as if God Himself should by His ministers exhort the people to be reconciled to God" (v. 20); to wit, by faithful obedience. They use the keys, therefore, when they persuade to faith and repentance. Thus do they reconcile men to God; thus they forgive sins; thus they open the kingdom of heaven, and bring in believers; much differing herein from those of whom the Lord spoke in the gospel, "Woe unto you lawyers, for ye have taken away the key of knowledge: ye have not entered in yourselves, and those that would have entered ye forbade" (Luke 11:52).
Rightly, therefore, and effectually do ministers absolve, when they preach the gospel of Christ, and thereby remission of sins; which is promised to every one that believes, even as every one is baptized; and testify of it that it particularly appertains to all. Neither do we imagine that this absolution is made any whit more effectual for that which is mumbled into some priest's ear, or upon some man's head particularly; yet we judge that men must be taught diligently to seek remission of sins in the blood of Christ, and that everyone is to be put in mind that forgiveness of sins belongs unto Him.
But how diligent and careful every penitent man ought to be in the endeavor of a new life, and in slaying the old man, and raising up the new man, the examples in the gospel teach us. For the Lord says to him whom He had healed of the palsy, "Behold thou art made whole, sin no more, lest a worse thing come unto thee" (John 5:14). Likewise to the adulterous woman which was delivered, He said, "Go thy way, and sin no more" (John 8:11). By which words He did not mean that any man could be free from sin, while he lived in this flesh; but He commends unto diligence and an earnest care, that we (I say) should endeavor by all means, and beg of God by prayer, that we may not fall again into sins, out of which we are risen after a manner, and that we may not be overcome of the flesh, the world, or the devil. Zacchaeus, the publican, being received into favor by the Lord, cries out in the gospel, "Behold, Lord, the half of my goods I give to the poor, and if I have taken from any man any thing by fraud, I restore him fourfold" (Luke 19:8). After the same manner, we preach that restitution and mercy, yes, and giving of alms, are necessary for them which truly repent. And generally out of the apostle's words, we exhort men, saying, "Let not sin reign in your mortal body, that ye should obey it through the lusts thereof. Neither give ye your members, as weapons of unrighteousness, to sin; but give yourselves unto God, as they that are alive from the dead; and give your members, as weapons of righteousness, unto God" (Rom. 6:12–13).
Wherefore, we condemn all the ungodly speeches of certain ones who abuse the preaching of the gospel and say, "To return unto God is very easy, for Christ has purged all our sins: forgiveness of sins is easily obtained: what, therefore, will it hurt to sin?" And, "We need not take any great care for repentance," etc. Notwithstanding, we always teach that an entrance unto God is open for all sinners, and that this God forgives all the sins of the faithful, only that one sin excepted which is committed against the Holy Ghost (Mark 3:28–29). And, therefore, we condemn the old and new Novatians and Catharists, and especially we condemn the pope's lucrative doctrine of penance; and against his simony, and simonaical indulgences, we use that sentence of Simon Peter, "Thy money perish with thee, because thou thoughtest that the gift of God might be bought with money. Thou hast no part or fellowship in this matter, for thy heart is not upright before God" (Acts 8:20–21).
We also disapprove of those who think that they themselves by their own satisfactions can make recompense for their sins committed. For we teach that Christ alone, by His death and passion, is the satisfaction, propitiation, and purging of all sins (Isa. 53:4). Nevertheless, we cease not to urge, as was before said, the mortification of the flesh; and yet we add further that it must not be proudly thrust upon God for a satisfaction for our sins (1 Cor. 8:8), but must humbly, as it becomes the sons of God, be performed as a new obedience to show thankful minds for the deliverance and full satisfaction obtained by the death and satisfaction of the Son of God."
