A religion is a human faith and trust in a deity or in an entity claiming the attributes of deity.
Cult is a informal term. It comes from the Latin colere, meaning circle. Like, a small group’s private religion. At one point the early church would have been considered a cult had you asked the religious community outside of it. It’s only its widespread nominal earthly success that has it NOT being called a cult today.
There are a plethora of religions. The bible says there are many “Lords” and many “gods.” And the evil apparition called Allah in Islam, is one of them.
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.
