until he comes out and says, “Jesus is the only way to the Father and heaven,” he is not a true Christian either.
I know many, many “liberal Christians” (oxymoron, I know) that won’t proclaim the exclusivity of salvation through Christ.
They have to twist themselves in knots, though, to try to avoid the idea that they are calling Jesus a liar in John 14:6.
Jesus showed us great GRACE by not giving us the option of saying “Jesus’ salvation AND something else” or that “Jesus was a good teacher but not the son of God”, etc.
By the way, the way that liberals are able to try to hold that they are “many ways to God” Christians is that they deny the divine inspiration of the Bible. They hold to this so tightly that they have “rescuing devices” for any proof that you offer for the divine inspiration.
Christian pluralists who share their faith universally can be called “idolators”. They simply worship themselves and in self-justification. Hell is a bad choice.
