Do you believe that there is a natural state of man that is inclined to life and truth?
Objective Morality?
If so, what “religion” best represents those beliefs?
What “other religions” can also represent those beliefs?
IMHO, if they can’t, they are a cult.
Do you still call Islam a religion?
I won’t get into arguments of subjective terminology. The bible warns about that (”quarrels about words.”)
Cult, or an implied cult-vs-religion divide, is one such argument. Cult is ultimately relative. The bible never used the term.
There isn’t any natural state of man any more with such an inclination. We have forgotten that the world only subsists at all through God’s blessings. Taking those blessings for granted doesn’t make them not God’s blessings. It does illustrate how patient God is, that He does not stop them the moment He gets snubbed for recognition.
