St. John preached the doctrine of exclusive salvation: "They went out from us, but they were not of us; for if they had been of us, they would no doubt continued with us; but they went out that they might be made manifest that they were not of us. These things have I written unto you concerning them that seduce you. Beloved, believe not every spirit, but try the spirits whether they are of God; because many false prophets are gone into the world. We are of God; He that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the Spirit of truth, and the Spirit of error. He that hath the Son hath life; and he that hath not the Son of God hath not life. And we know that we are of God, and the whole world lieth in wickedness. Whosoever transgresseth and _abideth not_ in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ he hath both the Father and the Son. If there come any unto you, and bring not _this doctrine_, receive him not into your house, neither bid him God speed; for he that biddeth him God speed, is partaker of his evil deeds." Lastly, the apostle Paul firmly believed and strenuously contended for the doctrine of exclusive salvation. He knew it was the hope of the righteous, and the bulwark of heaven. {73} What does he say? "Be it known unto you, therefore, men and brethren, that through this man is preached unto you the forgiveness of sins; and by him all that believe are justified from all things, from which ye _could not be justified_ by the law of Moses. For I am not ashamed of the gospel of Christ; for it is the power of God unto salvation to every one that believeth: to the Jew first, and also to the Greek, now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the _same thing,_ and that there be _no divisions_ amongst you: but that ye be perfectly joined together in the _same_ mind and in the _same judgment_, for it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions amongst you. Now this I say, that every one of you saith, I am of Paul and I of Apollos, and I of Cephas, and I of Christ. Is Christ divided? was Paul crucified for you? or were you baptized in the name of Paul? For ye are yet carnal; for whereas, there is amongst you envying and strife, and divisions; are ye not carnal, and walk as men? For while one saith, I am of Paul, and another I am of Apollos, are ye not carnal [A]? Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? For other foundation can no man lay than that is laid, which is Jesus Christ." [Footnote A: For whilst one saith, I am of Wesley; and another says, I am of Luther; and another says, I am of Calvin; and another says, I am of Campbell, are ye not carnal? We have need to learn again the _first principles_ of the gospel.]
