To be clear Arius believed God created Jesus and they were entirely seperate entities, taking the Son part very literally like Mormons do.

It is marginally better, because Mormons teach that God/The Holy Spirit basically boned Mary where Arius taught that Jesus was his first creation and just was never mentioned for the whole of the Old Testament as a way to get around the "Before Abraham" thing.

I think there's an upper limit to your cosmology being wrong but you'll still get to heaven and this is scrapping that ceiling.
