Which has been explained, several times over five pages, and by the parable of the vine -- so busted there -- it's not and never was polytheism. It has to do with deeply philosophical ancient debate about the exact nature of Christ. So lose the polytheism idea. It's a red herring, or a strawman, or whatever you want to call it. And anyway it has nothing to do with answering the question why, without evidence of your own to offer, and rejecting the evidence offered by history -- you are so confidently able to assert that what you believe is correct ,and what others believe is wrong.
