What is Christianity?The world's definition of Christian does not agree with the Biblical one. Nor does the Biblical one agree with many religious groups who call themselves Christian. The secular and widely used definition of Christianity is pretty much any group that claims the name or uses the Bible. The Biblical definition of Christian is far more restrictive. So many of those who call themselves Christian and are accepted as such by secular definition are in truth Christian Cults. A Christian Cult is a group that claims the name Christian, uses the Bible, and Christian words, terms, symbols, etc. but do not accept the core beliefs and teachings of Christianity. Their Christ does not line up with the Biblical Christ in example. Or they teach salvation other than the Biblical salvation, and so on for the critical and key issues required to actually being a Christian. Of course this results in arguments over who has the right to declare one a Christian or a Christian Cult. But any half knowledge of historical Christianity and Bible study quickly makes it clear who falls into which category with very few exceptions. Christian means “follower of Christ.” So if one does not follow the historical Christ they are not Christian. And their Christ is a false Christ. And if their Christ is false their teachings on the apostles and Christ will always be shown to be false as well.
