Forasmuch as God from the beginning would have men to be saved and to come to the knowledge of the truth (1 Tim. 2:4), therefore, it is necessary that there always should have been, and should be at this day, and to the end of the world, a church: that is, a company of the faithful, called and gathered out of the world; that is, a company (I say) of all saints, that is, of them who do truly know, and rightly worship and serve, the true God, in Jesus Christ the Savior by the Word and the Holy Spirit, and who by faith are partakers of all those good graces which are freely offered through Christ. These all are citizens of one and the same city living under one Lord, under the same laws, and in the same fellowship of all good things: for so the apostle calls them "fellow citizens with the saints, and of the household of God" (Eph. 2:19), terming the faithful upon the earth saints (1 Cor. 6:11) who are sanctified by the blood of the Son of God. Of these is that article of our Creed wholly to be understood: "I believe the catholic church, the communion of saints."
And seeing that there is always but "one God, and one mediator between God and man, Jesus Christ" (1 Tim. 2:5); also, one shepherd of the whole flock, one head of this body, and to conclude one Spirit, one salvation, one faith, one testament or covenant, it follows necessarily that there is but one church: which we, therefore, call catholic because it is universal, spread abroad through all the parts and quarters of the world, and reaches unto all times, and is not limited within the compass either of time or place. Here, therefore, we must condemn the Donatists who pinned up the church within the corners of Africa; neither do we allow of the Roman clergy, who vaunt that the Church of Rome alone is in a manner catholic.
The church is divided by some into divers parts or sorts: not that it is rent and divided from itself, but rather distinguished in respect of the diversity of the members that are in it. One part thereof they make to be the church militant, the other the church triumphant. The militant wars still on the earth and fights against the flesh, the world, the prince of the world, the devil, against sin, and against death. The other, being already set at liberty, is now in heaven and triumphs over all those things overcome, and continually rejoices before the Lord. Yet these two churches have notwithstanding a communion and fellowship among themselves.
Moreover, the church militant upon the earth has evermore had in it many particular churches, which must all notwithstanding be referred to the unity of the catholic church. This militant church was otherwise ordered and governed before the Law, among the patriarchs; otherwise under Moses, by the Law; and otherwise of Christ, by the gospel. There are but two sorts of people for the most part mentioned, to wit, the Israelites and the Gentiles; or they which, of the Jews and Gentiles, were gathered to make a church. There are also two testaments, the old and the new. Yet both these sorts of people have had, and still have, one fellowship, one salvation, in one and the same Messiah; in whom, as members of one body, they are all joined together under one head, and by one faith are all partakers of one and the same spiritual meat and drink. Yet here we do acknowledge a diversity of times, and a diversity in the pledges and signs of Christ promised and exhibited; and that now the ceremonies being abolished, the light shines unto us more clearly, our gifts and graces are more abundant and our liberty is more full and ample.
This holy church of God is called "the house of the living God" (2 Cor. 6:16), "builded of living and spiritual stones" (1 Peter 2:5) "founded upon a rock" (Matt. 16:18) "that cannot be removed" (Heb. 12:28) "upon a foundation, besides which none can be laid" (1 Cor. 3:11). Whereupon it is called "the pillar and foundation of the truth" (1 Tim. 3:15) that does not err, so long as it relies upon the rock Christ, and upon the foundation of the prophets and apostles. And no marvel if it does err, as often as it forsakes Him who alone is the truth. This church is also called "a virgin" (2 Cor. 11:2) and "the spouse of Christ" (Song 4:8) and "his only beloved" (Song 5:16). For the apostle says, "I have joined you unto one husband, that I might present you a chaste virgin unto Christ" (2 Cor. 11:2). The church is called "a flock of sheep under one shepherd" even Christ (Ezek. 34:22–23 and John 10:16) also, "the body of Christ" (Col. 1:24) because the faithful are the lively members of Christ, having Him for their head.
It is the head which has the preeminence in the body, and from whence the whole body receives life; by whose spirit it is governed in all things, of whom also it receives increase that it may grow up. Also there is but one head of the body which has agreement with the body; and, therefore, the church cannot have any other head beside Christ. For as the church is a spiritual body, so must it have a spiritual head like unto itself. Neither can it be governed by any other spirit than by the Spirit of Christ. Wherefore Paul says, "And He is the head of His body the church, who is the beginning, the first born of the dead, that in all things He might have the preeminence" (Col. 1:18). And in another place, "Christ (he says) is the head of the church, and the same is the Savior of His body" (Eph. 5:23). And again, "Who is the head of the church, which is His body, even the fullness of Him, which filleth all in all things" (Eph. 1:22–23). Again, "Let us in all things grow up into Him which is the head, that is Christ; by whom all the body being knit together, receiveth increase" (Eph. 4:15–16). And, therefore, we do not allow of the doctrine of the Roman prelates, who would make the pope the general pastor and supreme head of the church of Christ militant here on earth, and the very vicar of Christ, who has (as they say) all fullness of power and sovereign authority in the church. For we hold and teach, that Christ our Lord is, and remains still the only universal pastor, and highest bishop, before God His Father; and that in the church He performs all the duties of a pastor or bishop, even to the world's end: and, therefore, does not stand in need of any other to supply His place. For he is said to have a substitute, who is absent: but Christ is present in His church, and is the head that gives life thereunto. He did straitly forbid His apostles and their successors all superiority or dominion in the church. They, therefore, that by gainsaying set themselves against so manifest a truth and bring another kind of government into the church; see not that they are to be counted in the number of them of whom the apostles of Christ prophesied as Peter (2 Peter 2:1) and Paul (Acts 20:29; 2 Cor. 11:13; 2 Thess. 2:8–9) and in many other places.
Now by taking away the Roman head, we do not bring any confusion or disorder into the church. For we teach that the government of the church which the apostles set down, is sufficient to keep the church in due order; which, from the beginning, while as yet it wanted such a Roman head as is now pretended to keep it in order, was not disordered or full of confusion. The Roman head indeed maintains his tyranny and corruption which have been brought into the church: but in the meantime he hinders, resists, and, with all the might he can make, cuts off the right and lawful reformation of the church.
They object to us that there have been great strifes and dissensions in our churches, since they did sever themselves from the Church of Rome; and that, therefore, they cannot be true churches. As though there were never in the Church of Rome any sects, any contentions and quarrels; and that in matters of religion, maintained not so much in the schools as in the holy chairs, even in the audience of the people. We know that the apostle said, "God is not the author of dissension, but of peace" (1 Cor. 14:33); and, "Seeing there is amongst you emulation and contention, are ye not carnal?" (1 Cor. 3:3–4). Yet may we not deny but that God was in that church planted by the apostle, and that the apostolic church was a true church, howsoever there were strifes and dissensions in it. The apostle Paul reprehended Peter, an apostle (Gal. 2:11), and Barnabas fell at variance with Paul (Acts 15:39). Great contention arose in the church of Antioch, between them that preached one and the same Christ, as Luke records in the Acts of the Apostles (15:2). And there have at all times been great contentions in the church, and the most excellent doctors of the church have about no small matters differed in opinion: yet so as in the meantime the church ceased not to be the church for all these contentions. For thus it pleases God to use the dissensions that arise in the church to the glory of His name, to the setting forth of the truth, and to the end that such as are not approved might be manifest (1 Cor. 11:19).
Now, as we acknowledge no other head of the church than Christ, so we do not acknowledge every church to be the true church which vaunts herself so to be: but we teach that to be the true church indeed in which the marks and tokens of the true church are to be found. First and chiefly, the lawful or sincere preaching of the Word of God, as it is left unto us in the writings of the prophets and apostles, which all seem to lead us unto Christ, who in the gospel has said, "My sheep hear My voice, and I know them, and they follow Me; and I give unto them eternal life. A stranger they do not hear, but flee from him, because they know not his voice" (John 10:5, 27–28). And they that are such in the church of God have all but one faith and one Spirit; and, therefore, they worship but one God: and Him alone they serve in spirit and in truth, loving Him with all their hearts and with all their strength, praying unto Him alone through Jesus Christ the only mediator and intercessor; and they seek not life or justice but only in Christ, and by faith in Him: because they acknowledge Christ the only head and foundation of His church, and, being surely founded on Him, daily repair themselves by repentance and with patience bear the cross laid upon them; and besides, by unfeigned love joining themselves to all the members of Christ, they declare themselves to be the disciples of Christ, by continuing in the bond of peace and holy unity. They do withal communicate in the sacraments ordained by Christ and delivered to us by His apostles, using them in no other manner than as they received them from the Lord Himself. That saying of the apostle Paul is well known to all, "I received from the Lord that which I delivered unto you" (1 Cor. 11:23). For which cause we condemn all such churches as strangers from the true church of Christ, who are not such as we have heard they ought to be; howsoever, in the meantime, they brag of the succession of bishops, of unity, and of antiquity. Moreover we have in charge from the apostles of Christ "to shun idolatry" (1 Cor. 10:14; 1 John 5:21) and "to come out of Babylon, and to have no fellowship with her, unless we mean to be partakers with her of all God's plagues laid upon her" (Rev. 18:4; 2 Cor. 6:17).
But as for communicating with the true church of Christ, we so highly esteem of it, that we say plainly that none can live before God which do not communicate with the true church of God, but separate themselves from the same. For as without the ark of Noah there was no escaping when the world perished in the flood; even so do we believe that without Christ, who in the church offers Himself to be enjoyed of the elect, there can be no certain salvation: and, therefore, we teach that such as would be saved must not separate themselves from the true church of Christ.
But yet we do not so strictly shut up the church within those marks before mentioned, as thereby to exclude all those out of the church which either do not communicate in the sacraments (not willingly, nor upon contempt, but who, being constrained by necessity, against their will abstain from them, or else do want them); or in whom faith sometimes fails, though not quite decay, nor altogether die: or in whom some slips and errors of infirmity may be found. For we know that God had some friends in the world that were not of the commonwealth of Israel. We know what befell the people of God in the captivity of Babylon, where they wanted their sacrifices seventy years. We know what happened to St. Peter, who denied his Master, and what is wont daily to fall out among the faithful and chosen of God, which go astray and are full of infirmities. We know moreover what manner of churches the churches at Galatia and Corinth were in the apostles' times: in which the apostle Paul condemns divers great and heinous crimes; yet he calls them the holy churches of Christ (1 Cor. 1:2; Gal. 1:2).
Yes, and it falls out sometimes that God in His just judgment suffers the truth of His Word and the catholic faith and His own true worship to be so obscured and defaced, that the church seems almost quite razed out, and not so much as a face of a church remains; as we see fell out in the days of Elijah (1 Kings 19:10, 14) and at other times. And yet, in the meantime, the Lord has in this world, even in this darkness, His true worshippers, and those not a few, but even seven thousand (v. 18) and more (Rev. 7:4). For the apostle cries, "The foundation of the Lord standeth sure, and hath this seal, The Lord knoweth who are His" (2 Tim. 2:19). Whereupon the church of God may be termed invisible: not that the men whereof it consists are invisible; but because, being hidden from our sight, and known only unto God, it cannot be discerned by the judgment of man.
Again not all that are reckoned in the number of the church are saints, and lively and true members of the church. For there are many hypocrites which outwardly hear the Word of God and publicly receive the sacraments, and seem to pray unto God alone through Christ, to confess Christ to be their only righteousness, and to worship God, and to exercise the duties of charity to the brethren, and for a while through patience to endure in troubles and calamities. And yet they are altogether destitute of the inward illumination of the Spirit of God, of faith and sincerity of heart, and of perseverance or continuance to the end. And these men are for the most part at the length laid open what they are. For the apostle John says, "They went out from among us, but they were not of us: for if they had been of us, they would have tarried with us" (1 John 2:19). Yet these men, while they pretend religion, are accounted to be in the church, however indeed they are not of the church. Even as traitors in a commonwealth, before they are detected are counted in the number of good citizens; and as the cockle and darnel and chaff are found among the wheat; and as tumors and swellings are in a perfect body, when they are rather diseases and deformities than true members of the body. And, therefore, the church is very well compared to a dragnet which draws up fish of all sorts, and to a field wherein is found both darnel and good corn (Matt. 13:25–26). We are to have a special regard that we judge not rashly before the time, nor go about to exclude and cast off or cut away those whom the Lord would not have excluded nor cut off, or whom, without some damage to the church, we cannot separate from it. Again, we must be very vigilant lest the godly falling fast asleep, the wicked grow stronger and do some mischief to the church.
Furthermore we teach, that it is carefully to be marked wherein especially the truth and unity of the church consists, lest we either rashly breed or nourish schisms in the church. It consists not in outward rites and ceremonies, but rather in the truth and unity of the catholic faith. This catholic faith is not taught us by the ordinances or laws of men, but by the Holy Scriptures, a compendious and short sum whereof is the Apostles' Creed. And, therefore, we read in the ancient writers that there were manifold diversities of ceremonies, but that those were always free; neither did any man think that the unity of the church was thereby broken or dissolved. We say then that the true unity of the church consists in several points of doctrine: in the true and uniform preaching of the gospel, and in such rites as the Lord Himself has expressly set down; and here we urge that saying of the apostle very earnestly, "As many of us, therefore, as are perfect, let us be thus minded. If any man think otherwise, the Lord shall reveal the same unto him. And yet in that whereunto we have attained, let us follow one direction, and all of us be like affected one towards another" (Phil. 3:15–16).
