With so many books being written recently criticizing churches for what they ought to do and be, how they ought to minister rightly, and so many other theories on how churches can be more "this" or less "that," I thought this quote from John Calvin to be an excellent mediator of wisdom and balance for folks like me who may feel a bit tossed about by the contradicting theories and ideas on the subject of ecclesiology. In fact, I'm looking forward to studying the Institutes throughout the year, with the R21 bloggers. Enjoy the read below, and I hope it is as edifying to you as it was for me. God bless.
The Institutes, Book Four, Chapter 1, Section 12
12. "When we say that the pure ministry of the word and pure celebration of the sacraments is a fit pledge and earnest, so that we may safely recognise a church in every society in which both exist, our meaning is, that we are never to discard it so long as these remain, though it may otherwise teem with numerous faults. Nay, even in the administration of word and sacraments defects may creep in which ought not to alienate us from its communion. For all the heads of true doctrine are not in the same position. Some are so necessary to be known, that all must hold them to be fixed and undoubted as the proper essentials of religion: for instance, that God is one, that Christ is God, and the Son of God, that our salvation depends on the mercy of God, and the like. Others, again, which are the subject of controversy among the churches, do not destroy the unity of the faith; for why should it be regarded as a ground of dissension between churches, if one, without any spirit of contention or perverseness in dogmatising, hold that the soul on quitting the body flies to heaven, and another, without venturing to speak positively as to the abode, holds it for certain that it lives with the Lord?  The words of the Apostle are, "Let us therefore, as many as be perfect, be thus minded: and if in anything ye be otherwise minded, God shall reveal even this unto you" (Phil. 3:15). Does he not sufficiently intimate that a difference of opinion as to these matters which are not absolutely necessary, ought not to be a ground of dissension among Christians? The best thing, indeed, is to be perfectly agreed, but seeing there is no man who is not involved in some mist of ignorance, we must either have no church at all, or pardon delusion in those things of which one may be ignorant, without violating the substance of religion and forfeiting salvation. Here, however, I have no wish to patronise even the minutest errors, as if I thought it right to foster them by flattery or connivance; what I say is, that we are not on account of every minute difference to abandon a church, provided it retain sound and unimpaired that doctrine in which the safety of piety consists,  and keep the use of the sacraments instituted by the Lord. Meanwhile, if we strive to reform what is offensive, we act in the discharge of duty. To this effect are the words of Paul, "If anything be revealed to another that sitteth by, let the first hold his peace" (1 Cor. 14:30). From this it is evident that to each member of the Church, according to his measure of grace, the study of public edification has been assigned, provided it be done decently and in order. In other words, we must neither renounce the communion of the Church, nor, continuing in it, disturb peace and discipline when duly arranged. "
