When you said “if God exist, he can’t be defined” you made it about all monotheistic Gods; not just the God of Abraham. If you meant specifically the God of Abraham, you should have clarified by saying so hence my misunderstanding of the point you made.
Consider my view the God of Abraham for now on for discussion, but this does preclude that Monotheists do not believe in many Gods . Other religions are not as clear nor consistent in belief of a Monotheistic God. Belief in Monotheism precludes the existence of many other different kinds of Gods.
Again, Monotheists believe their God is the only universal God, and define God in many conflicting ways, which is a contradiction.
It is obvious you do not believe in Gods, and I acknowledge that. You do not seem to comprehend the substance of my argument that from the human perspective we cannot define God, if it is believed, at the exclusion of other religious beliefs in a Monotheistic God.
That’s not what I asked. What’s preventing (since we’re talking about the God of Abraham) a Christian from reading the bible, using the descriptions of God from the bible to describe him?
Nothing as I said before. People can believe in any kind of Monotheistic God the want. Christians for the most part do not believe in many kinds of Gods, ie like the Greeks.
