Paul on Angels of Other Gospels

Paul writes the Galatian churches with a heavy heart because the one true gospel he had preached there and by which they had been saved was under siege by rival messages advocating deeds, rituals and laws as necessary additions."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." This sermon presents a review of the true message before the false messages brought by "angel messengers."
