They are all against it!
"Our indulgence ought to extend much farther in tolerating imperfection of conduct. Here there is great danger of falling, and Satan employs all his machinations to ensnare us. For there always have been persons who, imbued with a false persuasion of absolute holiness, as if they had already become a kind of aerial spirits—as if they had bean some angels of Paradise, spurn the society of all in whom they see that something human still remains. Such of old were the Cathari and the Donatists, who were similarly infatuated. Such in the present day are some of the Anabaptists, who would be thought to have made superior progress. Others, again, sin in this respect, not so much from that insane pride as from inconsiderate zeal. Seeing that among those to whom the gospel is preached, the fruit produced is not in accordance with the doctrine, they forthwith conclude that there no church exists. The offence is indeed well founded, and it is one to which in this most unhappy age we give far too much occasion. It is impossible to excuse our accursed sluggishness, which the Lord will not leave unpunished, as he is already beginning sharply to chastise us. Woe then to us who, by our dissolute licence of wickedness, cause weak consciences to be wounded! Still those of whom we have spoken sin in their turn, by not knowing how to set bounds to their offence. For where the Lord requires mercy they omit it, and give themselves up to immoderate severity. Thinking there is no church where there is not complete purity and integrity of conduct, they, through hatred of wickedness, withdraw from a genuine church, while they think they are shunning the company of the ungodly. They allege that the Church of God is holy. But that they may at the same time understand that it contains a mixture of good and bad, let them hear from the lips of our Saviour that parable in which he compares the Church to a net in which all kinds of fishes are taken, but not separated until they are brought ashore. Let them hear it compared to a field which, planted with good seed, is by the fraud of an enemy mingled with tares, and is not freed of them until the harvest is brought into the barn. Let them hear, in fine, that it is a thrashing-floor in which the collected wheat lies concealed under the chaff, until, cleansed by the fanners and the sieve, it is at length laid up in the granary. If the Lord declares that the Church will labour under the defect of being burdened with a multitude of wicked until the day of judgment, it is in vain to look for a church altogether free from blemish (Mt. 13)." (Institutes 4.1.13)
"And, to speak plainly, among all the churches in the world which are free from idolatry and persecution, it is not different opinions, or a difference in judgment about revealed truths, nor a different practice in sacred administrations, but pride, self-interest, love of honour, reputation, and dominion, with the influence of civil or political intrigues and considerations, that are the true cause of that defect of evangelical unity that is at this day amongst them; for set them aside, and the real differences which would remain may be so managed, in love, gentleness, and meekness, as not to interfere with that unity which Christ requireth them to preserve."
