'Christian cults' are usually cults that use christian terminology to decieve their members who are comfortable using christian terminology.
All of them have one thing in common, they deny the deity of the Lord Jesus Christ.
A true Christian believes that Jesus is fully God.
All of them twist scripture, many claim they have the only true version of the bible and most of them are founded on the word of one or two very persuasive people.
Most cults bind their followers through fear tactics, many focus on apocalyptic false propehcies and mind control tactics.
Some examples of 'Christian cults" are: Jehovah's witnesses, Mormons, Christian science, 'A course in miracles' etc etc etc.
All lead to death, only the true Jesus Christ can lead to eternal life!
