But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed Galatians 1:8-9.
One thing to remember here is that Galatians was written quite awhile before anyone had heard of Mormonism(to my knowledge). If the message keeps changing,then something is suspect here.
Precisely. Galatians sets so many errors right. I love Paul’s teaching from Christ. John, in his letters, also warned against antichrists. He shut Mohamed down before he ever started. This is the power of Scripture, it carries true authority from God (because His Spirit breathed it out).
