I'm going to be honest with you, most "Christians" consider Jehovah's Witnesses and Mormons cults, (as well as other less well known groups). So I am not going to hide this fact and beat around the bush, it won't do us any good to pretend there are no differences, but let's look at what those differences may be.
Here is a good definition of a cult that fits the general meaning I've always heard about in Church and through research:
You may not be aware of any central Bible doctrines that your group denies, but why then do most Christians consider it a cult? If your group truly fits this definition, then there must be a core, essential teaching that the rest of historical Christianity believes in yet is denied through your group's teaching. Now, if everyone else thinks it is essential and your group denies it, this is a pretty serious discrepancy! It behooves you to find out what the differences are, and to be 100% sure you are right!!!
Whether you were brought up in this group or introduced later, it doesn't matter; it is either right or wrong.
