“If we would hold fast that which is good, we must not tolerate or countenance any doctrine that is not the pure doctrine of Christ’s Gospel. There is a hatred that is downright charity: that is the hatred of erroneous doctrine. There is an intolerance which is downright praiseworthy: that is the intolerance of false teaching in the pulpit. Who would ever think of tolerating a little poison given to him day by day? If men come among you who do not preach all the counsel of God, who do not preach of Christ, and sin, and holiness, of ruin, and redemption, and regeneration,—or do not preach of these things in a scriptural way, you ought to cease to hear them. You ought to act upon the injunction given by the Holy Ghost in the Old Testament: ‘Cease, my son, to hear the instruction that causeth to err from the words of knowledge’ (Prov. 19: 27). You ought to carry out the spirit shown by the Apostle Paul, in Gal. 1:8: ‘Though we, or an angel from heaven, preach any other Gospel unto you than that which we have preached, let him be accursed.’ If we can bear to hear Christ’s truth mangled or adulterated—and can see no harm in listening to that which is another Gospel—and can sit at ease while sham Christianity is poured into our ears—and can go home comfortably afterwards and not burn with holy indignation—if this be the case, there is little chance of our ever doing much to resist Rome. If we are content to hear Jesus Christ not put in His rightful place, we are not men and women who are likely to do Christ much service, or fight a good fight on His side. He that is not zealous against error, is not likely to be zealous for truth.” — J.C. Ryle
