Actually, you do. In Acts 11:25 The article is in error to say this term was used to describe the followers of Paul, though. For at this time, Paul was still using his Jewish name Saul and was subordinate to Barnabas as the leader of the church at Antioch. It was not until later that Paul became a principal leader of the church.

It is also to be noted that the church did not call itself "Christian". This was a name given them by outsiders. The early believers referred to their belief as "the Way" (Acts 24:14). Like "Christian" the term "Nazarene" probably came from outsiders, not from the believers themselves.

These skeptical articles often make me laugh. This one begins by saying "It would probably come as a shock to most Christians today that the original followers of Jesus were never called Christians." and then goes on to quote the passage in Acts where it says "It was in Antioch the disciples were first called 'Christians'". So why would it be a shock to learn what is plainly stated in our own scriptures?
