Why Is It Hard To Call Jesus Caesar

Chuck Colson commented that in the early church, if a person stood up in a public arena and cried out, “Jesus is God!” no one would be offended because the Romans and Greeks believed in many gods. To call Jesus “God” would not have seemed revolutionary or even risky. But if a Christian stood up and shouted, “Jesus is Lord,” he would be putting his own life at risk.
Why?
The Roman Caesars claimed the title of Lord, and this was a central reason why Christians faced persecution. They were willing to obey Roman laws, but they were not willing to call Caesar “Lord.” Back then, proclaiming Christ as Lord was seen as an act of treason!
