How can a Christian reject part of the Bible and still call themselves a Christian?

You're right on this one.  That's a problem with religions.  A human institution takes the place of following Christ.

To clarify, would a religion consecrating such marriages then be considered a false religion ?

Could someone who attends such a denomination, but is still on their original spouse, but yet donates money to such an organization still be assured of Salvation ?


To what extent could we say that individual is sincerely imbued with the entirety of Jesus sacrifice ??

I just know that if a religion takes a stance against Christ's teachings they are wrong. Someone's salvation is not based on where they donate their money to. You're really lost as to what the bible says in regard to salvation.
