What distinguishes Christianity from cults is the Jesus Christ of the Bible. John warns us in 1 John 4:2-3 1Jo 4:2 NIV - This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God, 1Jo 4:3 NIV - but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world. Since Jesus claims to be The Way, The Truth, The Life, (John 14:6) it’s easy to identify a cult; Anything But, Jesus Christ Alone. Really Simple, Really Obvious.
