Good research uses more than one reference source...
Yes it does. Good research also does not post the bogus source without referencing a good one. Good researchers do not post bogus sources and force their readers to find good ones on their own.
Either God changes, or the claimed revelations are bogus...
I believe that more than one of us mentioned a third possibility; that God does not change, but people do. Your false dichotomy is, well....false.
did you read my example of the parent and the child? A father treats his adult son very differently from the way he treated the same son when he was two. The father didn't change, but the child does.
People change. Our societies do, our cultures do, our understanding and knowledge do...that God gives different or evolving revelations to one group than He does to another does not necessarily mean that HE changes.
That we believe in modern and continuous revelation indicates, I believe, that we are aware that while God may not change, WE don't remain stagnant. His dealings with us will alter as our understanding does. If that were not so, we wouldn't have had any revelation from Him after Moses, now, would we? Shoot, we wouldn't have heard from Him about anything after Abraham...or perhaps Adam. But God does NOT change, and He has dealt with us precisely the same way as He has from the beginning; with revelation to prophets.
He does not demand that prophets be perfect, or perfect of understanding. God is perfect. We are not.
