Almost every brand of Christianity recognizes at least some form of pseudo-Christianity within the broad spectrum of Christian denominations. Therefore the concept of a religion projecting a false picture or understanding of Christ is a basic element of Christian doctrine in general. Just as you can’t judge a book by its cover, you cannot blindly accept a religious group which claims allegiance to Jesus.
Of course most such groups think that they are the real Christians and those that do not conform to their doctrinal distinctions are subject to the same eternal fate as all those who reject Christianity out right. Pseudo-Christians might as well be atheists for all the good it will do them.
I wonder seriously whether all of those who recognize pseudo Christians outside their sacred group aren’t themselves the pseudo-Christians. Christ came to reconcile the entire world to God, so where’s the need to identify who got reconciled and who just thinks they did?
How ironic is it that trying to label others as unacceptable makes one an enemy of Christ and a pretender to the identity of Christian.
