////What I find interesting is that Christ (Greek for Messiah) started off as a title, and nowadays is thought of as a personal name, while Caesar was originally a personal name and became a title (Kaiser, Czar etc).////

In all likelihood, Jesus and Christ were at one time separate mythological figures. I find it strange that the historians of Rome never wrote about Jesus. They called him only Christ or Chrestus to the point where it becomes difficult to believe they knew of any other name.

Then you go down in the catacombs and there are almost no New Testament scenes. The only cross depicted there is the swastika.
