Charles Spurgeon said:
"Numbers of good brethren in different ways remain in fellowship with those who are undermining the Gospel; and they talk of their conduct as though it were a loving course which the Lord will approve in the day of His appearing. The bounden duty of a true believer towards men who profess to be Christians, and yet deny the Word of the Lord, and reject the fundamentals of the Gospel, is to come out from among them (II Cor 6:14-18)…
Complicity with error will take from the best of men the power to enter any successful protest against it. If any body of believers has errorists among them, but were resolute to deal with them in the Name of the Lord, all might come right, but confederacies founded upon the principle that all may enter, whatever views they hold, are based upon disloyalty to the truth of God. If truth is optional, error is justifiable….
It is hard to get leaven out of dough, and easy to put it in. This leaven is already working. Our daring to unveil this deep design [that is, this deep-laid scheme] is inconvenient, and of course it brings upon our devoted head all manner of abuse.
But that matters nothing
so long as the plague is stayed.
Oh, that those who are spiritually alive in the churches may look to this thing, and may the Lord Himself baffle the adversary."
