You haven't studied cults and religions extensive enough. There is a BIG difference in Cults and Religions and it is not about size of followers!
Religions do NOT grant special powers but of understanding a faith to walk a spiritual path. Cults promises special powers that are supernatural which is a false sense of delusion. All cults are false teachings. Cults adopt a religion and twist it.
Christians receive spiritual gifts, such as speaking in tongues, divining the future, and laying of hands for healing, etc.
According to 1 Corinthians 12:8-10 , "To one there is given through the Spirit a message of wisdom, to another a message of knowledge by means of the same Spirit, 9 to another faith by the same Spirit, to another gifts of healing by that one Spirit, 10 to another miraculous powers, to another prophecy, to another distinguishing between spirits, to another speaking in different kinds of tongues,[a] and to still another the interpretation of tongues."
Does this make Christianity a cult? I don't think so. It seems to be a religion to me, but so does Falun Gong.
What then makes the difference between religions and cults?
Then what?
By the way, I am not a troll -- I genuinely believe what I'm writing. I'm an amateur philosopher and to me this is important. (I guess that I have a doctorate in philosophy so maybe I'm not an amateur... my PhD is in a different field, so does this count?)
