Which is why they have been so easily deceived by the conservative movement, which claims to be of Christ, but other than abortion turn away from His teachings.
Where does the "true and pure Gospel of God" come from? I think that the KJV of the Bible is the best, despite knowing that it is full of what many would consider errors. I think that the books after the 4 Gospels probably have the most repulsive doctrine. AND, there seems to be so much chaos there that many ignore it.
Taking a single point is head covering. Here in America, women in main stream society seldom do it. Yet it is often assumed in the OT. In the later part of the NT, it seems assumed, especially when a woman is praying. Thankfully, I live in an area where I can cover, or not, at will, leaving me to devoutly seek God's will for me.
I know of places where saying that Jesus is the Son of God will cause you to lose your head. Yet, Christians believe it. Most don't know that to Muslims, Jesus (ISA PBUH) is the best prophet of Allah SWT. Their reasoning is that if God is the most supreme, he can not possibly have a son. To me, that is rather convoluted thought, so I don't bother to quarrel with them. I like my head.
I have been yelled at over the idea that God is one or three persons. I think the Bible is clear on that but do not think it to be worth it to quarrel over it.
