John the Baptist preached the doctrine of exclusive salvation: "And now also the axe is laid unto the root of the trees; therefore every tree which bringeth forth not good fruit is hewn down and cast into the fire."
Jesus Christ preached the doctrine of exclusive salvation: "Verily, verily, I say unto you, except a man be born of water and of the spirit he cannot enter into the kingdom of God. Except ye repent, ye shall all likewise perish. I am the way, the truth, and the life; no man cometh unto the Father but by me. He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. There shall be one fold and one shepherd. Holy Father, keep through thine own name those whom thou hast given me, that they may be one as we are. Go ye into all the world, and preach the gospel to every creature; he that believeth and is baptized shall be saved, but he that believeth not shall be damned." Exclusive enough this. There were many Pharisees, Sadducees, and Essenes, in the days of Jesus, but their religions were not sufficiently exclusive: "Except your righteousness exceed the righteousness of the Scribes and Pharisees, ye shall in no case enter into the kingdom of heaven."
On the day of Pentecost, Peter, filled with the Holy Ghost, preached the doctrine of exclusive salvation to men of every nation under heaven. Hear him: "Repent and be baptized every one of you, in the name of Jesus Christ. Save yourselves from this untoward generation." Three thousand persons believed the word of exclusive salvation by Peter, and in token thereof were baptized the same day. The reader will recollect that these three thousand persons were not what are generally considered wicked sinners, but religious, devout men, who had proven their sincerity and faithfulness by coming up from all nations to Jerusalem, expressly "to worship." But their religion, their devotion, their worship was insufficient; it was not exclusive enough, and Peter had sufficient charity to boldly proclaim this. Sincerity in an individual is no proof that he is in the "right way." I might wish to go from Manchester to Edinburgh, but if I unwittingly started on the London road, with my back to Edinburgh, I should not reach the place of my destination, but every step I took would increase the distance between me and it. The only, the exclusive means by which I could reach Edinburgh, would be to travel on the road to Edinburgh.
Hear Peter further: "Neither is there salvation in any other, for there is none other name under heaven given amongst men whereby we must be saved."
Though Cornelius received the ministration of angels, and the gift of the Holy Ghost, he found that salvation was exclusive, and Peter commanded him to be baptized, in order that he might be saved.
The devils know the truth of the doctrine of exclusive salvation. Said one,—"Jesus I know, and Paul I know, but who are ye?"
James preached the doctrine of exclusive salvation: "But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed. For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all."
Jude preached the doctrine of exclusive salvation. "It was needful for me to write unto you and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints. How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts. These be they who separate themselves; sensual, having not the Spirit."
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. 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."
