A Christian is one who follows the teaching of Christ.
That is not the same as the multitude who claim to be Christian.

"A Christian is one who follows the teaching of Christ."

Following the teachings of Christ is great, but it doesn't make one automatically a Christian, at least not according to the teachings of the Bible. My brother is a Hare Krishna devotee who believes in and follows many of the teachings of Christ, but he would not in any way describe himself as a Christian.
