I haven't been following this discussion, nor seen your sound argument for the oneness of God.
It's obvious, since the argument I cited from Aquinas about God's oneness does not depend on the Bible as an authority, as you hoped. I made a calculated assumption by posting in a message board with the name of a church that at least claims belief in the existence of God, that the premise "God exists" would be agreed upon. But, if you really want 5 proofs for that (none of which depend on the Bible for anything, only reasonable understanding of the natural world) here is the link:
http://www.newadvent.org/summa/1002.htm (scroll down to Article 3, unless you also want to see the argument that we can know that God exists, then also read Article 2) (or The Summa Theologica, Prima Pars, Question 2, Article 3 by Thomas Aquinas). I doubt, however, you will read any of it, as you obviously seem content with spouting out criticisms wihtout even reading what you criticize (see quoted statement above) and do not welcome anything outside of your stereotypes:
I can guarantee you have presented no sound argument for the oneness of God in the sense of a reality of a God. What you may have presented is an argument which uses the Bible as authority and the premise that a god exists as well as particulars for that god, is assumed true based upon the claims within the Bible. That doesn't mean the premises which you supplied are really true, in the sense of being a reflection of the world we all experience and observe.
What basis can you "guarantee" anything? You didn't even read anything, as you admit, and if you had, you'd see that you are clearly wrong about many assertions you make, given the argument I posted ealier in this thread. I find it ironic that while you imply you like to think about things critically (as opposed to those who rely on the Bible for arguments), you don't even read what you are criticizing! Great example for everyone of your critical thinking skills.
