But not contradictory.
I’ve heard some Christians say this. I’ve also heard Muslims say similar things about their non-coreligionists. Etc. Another story for another time. Point for now is, this Christian doesn’t say such a thing. And wouldn’t.
Really. Some of the "Christians" right here have told me that I am doomed to hell for not being a Christian.
Then it seems to me they are saying more than they really know. For they don't know how you will "turn out," what you will become, etc.; and they don't know how Christ will judge you. For all they know, He may have a very special place in His heart for you....
In any case we are directed to love our neighbor as ourself. To flat-out tell someone that they are damned to Hell doesn't strike me as being particularly neighborly.... FWIW
