LOL! We don’t have quite so narrow a definition of Christianity. If you believe Jesus Christ is your Savior and Redeemer, and there is no other way to return to God’s presence, I think you pretty much qualify as a Christian as far as I’m concerned.
Of course, before you can say who is a Christian, you need to provide a definition.
As Jesus said, wide is the road leading to destruction; narrow is the way leading to life.
...there is no other way to return to God’s presence, I think you pretty much qualify as a Christian as far as I’m concerned.
Yes, there is no other way (John 14:6), but what would you say to the Mormon who says "all" are resurrected because of Jesus & therefore "all" are "saved?"
