Perversion of the Gospel

⁶ I am astonished and extremely irritated that you are so quickly shifting your allegiance and deserting Him who called you by the grace of Christ, for a different [even contrary] gospel; ⁷ which is really not another [gospel]; but there are [obviously] ^[a]some [people masquerading as teachers] who are disturbing and confusing you [with a misleading, counterfeit teaching] and want to distort the gospel of Christ [twisting it into something which it absolutely is not]. ⁸ But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we [originally] preached to you, let him be condemned to destruction! ⁹ As we have said before, so I now say again, if anyone is preaching to you a gospel different from that which you received [from us], let him be condemned to destruction!

¹⁸ I testify and warn everyone who hears the words of the prophecy of this book [its predictions, consolations, and admonitions]: if anyone adds [anything] to them, God will add to him the plagues (afflictions, calamities) which are written in this book;^{(A) 19} and if anyone takes away from or distorts the words of the book of this prophecy, God will take away [from that one] his share from the tree of life and from the holy city (new Jerusalem), which are written in this book.
