“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.”
Galatians 1:8
Mormonism and Islam both started with their founders claiming an angel delivered new teachings. Joseph Smith said Moroni gave him the Book of Mormon. Muhammad said Gabriel gave him the Quran. But the Bible is crystal clear: if anyone, even an angel, shows up with a message that goes against the original Gospel about Jesus, that message must be rejected, no exceptions. These stories are in direct conflict with what God has already revealed.
Don’t be fooled by new revelations. Hold tightly to the truth.
