I agree with one thing that you wrote: We just can't know these things completely or exhaustively.Because that is what the Bible says. Each person has different primary roles in the salvation of humans and redemption of creation.
There are finer nuances that shouldn't be overlooked.
Not entirely. There are differences stated.
So what? Just don't bother with this thread then. There are plenty of others you can read and post in.
It certainly can to a point. Otherwise everything God says is unknowable.
No, it isn't. God has revealed himself to us using reasoning and human language, so that we can know some things about him. We just can't know these things completely or exhaustively.
Except that Cooper can't explain the Trinity at all and doesn't believe in the Trinity. Just go back and look at his comments on the diagram that explains the Trinity.
BTW, Cooper does believe in the Trinity. You are clearly maligning the faith of a very serious, devoted Christian. By doing so, aren't you violating the ToS 1.1? "Grant others the courtesy to be understood and acknowledge their views" and ToS 1.4: "Do not misquote or misrepresent another member. Do not state a negative opinion about a member's denomination, leaders, founders, or the veracity of a member's faith."
