At best you are using some commonalities at the expense of their distinctions. And what is your defining source on what monotheism is?
This is the hole in any Humanistic argument - their defining source authority is either their own opinion or the opinion of some other human, and is no better of an authority than any other opposing opinion.
And if they refer to some collective opinion, well, those change with time as well, so who's to say which is "right"?
My “source” is Torah, which I see more as God and Man centered without involving those “Luciferian” aspects that are also attributable to God alone.
I believe that when God said, “I alone am The Lord”, he meant it. I also think that God’s principal demand of us is that we act decently toward each other.
As for Jesus, even without divinity, he was moshiach (the messiah) in that the United States could never have been founded without his influence.
