There is only one gospel, only one “good news” that a person needs to hear in order to be saved. It is the good news of Jesus Christ. It is the “news” that we are saved not by our own works but by grace through faith in Jesus Christ (Eph. 2:8-9).
A person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified. (Gal. 2:16)
Paul issued a solemn warning in Galatians 1:6-9 that departing from this true gospel is departing from God. Any “gospel” other than this, whether in the name of Christianity or of other religion, is dangerous to one’s soul.
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. (Gal. 1:8-9)
If anyone has no love for the Lord, let him be accursed. (1 Cor. 16:22)
