'Another Gospel' in the Bible

For if he indeed that cometh preach another Jesus, whom we have not preached, or ye receive another spirit, which ye have not received, or another gospel, which ye have not embraced, ye might well bear with him.

I marvel that ye are so quickly departed from him that called you, by the grace of Christ into another gospel

But though even we, or an angel from heaven, preach unto you another gospel, different from that which we have preached to you, let him be an anathema.
