The following teachings of Herbert Armstrong have been thoroughly refuted here and elsewhere:
1. The nature of God. His teachings about the Trinity, and more particularly those that were related to the Holy Spirit.
2. The nature of the human potential. His teaching that man would one day be equal to God.
3. The biblical origins of the English-speaking nations of the earth. His teaching that the people of the United States and Britain are the descendants of the birthright tribes of Israel (Ephraim and Manasseh).
4. That the return of Jesus Christ to this earth is imminent. He repeatedly engaged in date setting and misleading people about the signs of the times.
5. That Christians are obligated to observe the commandments of Torah (including the weekly Sabbath, Holy Days, tithing, and clean and unclean animals as food.
6. That the symbolism of the Holy Days reflected Armstrong's understanding of God's plan. More particularly, his understanding of the meaning of Atonement, Trumpets, and Tabernacles.
7. The nature, purpose, and fate of the angels. Especially, as it related to Satan and his demons.
8. The nature of the ekklesia. His teachings about government within the Church, the composition of the Church, disfellowshipping, and that traditional Christians were deceived members of a false church, a pseudo-ekklesia.
9. The influence of paganism on Christianity. More particularly, his teachings regarding Christmas, Easter, Halloween, Saint's Days, etc., and his rejection of the cross as a Christian symbol.
10. The interpretation of prophecy. More particularly, his headline theology and insinuating modern nations, institutions, and leaders into biblical prophecies.
11. The nature of the Gospel. More particularly, his de-emphasis on the person and work of Jesus of Nazareth and what all of that meant for humanity.
12. The nature of the Kingdom of God. He ignored the anti-authoritarian message of Christ and dismissed the fundamental change that was being wrought in the nature of humanity. Instead, he emphasized a literal government which would forcibly impose its will on everyone.
13. The nature and purpose of human sexuality. More particularly, his teachings about dating, marriage, homosexuality, divorce and remarriage, child rearing, appropriate clothing, makeup, and what constituted sexual lust.
14. The nature and role of faith and works in the life of a Christian. His understanding of love, mercy, forgiveness, repentance, faith in Christ, and physical works was twisted and inconsistent with what is revealed in Scripture.
15. The way that Scripture was used and interpreted. Mr. Armstrong's insistence on literalism and proof-texting; and his rejection of all textual criticism, along with the way he ignored context, doomed his interpretations of Scripture to failure.
