Possibly, possibly not.
the Navajo keep a lot of their religious ideas to themselves, so it's hard to say exactly what they are doing.
But it looks to me like they are falling into this error
Romans 1: 23 and traded the glory of the incorruptible God for the likeness of an image of corruptible man, and of birds, and four-footed animals, and creeping things.
So the Muslims would be better off in that respect. As I understand it, they don't make images of God. (Classic Islamic art is just designs, from what I've seen.)
Don't get me wrong, Muslims are wrong about a lot of things! But making literal idols is something they don't do, I'm pretty sure.
My brother, idol isn't only statue. Money or fame can be idol. We as profess christian may worship money
And I believe in God prespective, No one can worship mammon and God in the same time.
It doesn't matter If we profess Christian worship money, than we not worship God
Matthew 6:24 King James Version (KJV)
24 No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
It doesn't say worship here but I believe worship include the word serve.
Can you serve God but refused to worship God?
