Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness. -2 Peter 3:17
One of the greatest means of destroying peace is error. Error in doctrine leads to the most lamentable consequences with regard to the peace of the church. I have noticed that the greatest failings out have been among those who are most erroneous in doctrine. Though I admit that some called Calvinists are the most quarrelsome set breathing, this is the reason-while they have the main part of the truth, many of them are leaving out something important, and therefore God chastises them because they are some of His best children. It may be a sign of life that they are so eager after truth, that they kill one another in order to get it; but I wish they would leave off their quarrelling for it is a disgrace to our religion. If they had more peace I might hope better for the progress of truth.
Error is the root of bitterness in the church. Give us sound doctrine, sound practice, sound church government, and you will find that the God of peace will be with us. My brethren, seek to uproot error out of your own hearts. If one of you do not really believe the great cardinal doctrines of the gospel, I beseech you, then, for the good of the church to leave it, for we want those who love the truth.~ C.H. Spurgeon
