Christians are always talking about Jesus? Why are Christian talking that often about Jesus Christ? Is that really necessary? Where does it come from?

It is true that Christians are talking often about Jesus Christ. There are two reasons for it. The first reason is that Christianity begun with the person Jesus Christ. His life, deeds and words are the starting points of Christianity. Jesus is the core, the ultimate center of Christianity. The other reason is the name 'Christians'. When Christianity emerged the first believers where not called 'Christians' Actually was the word 'Christian''  first used as a four letter word. In the city Antioch the first followers of Jesus Christ where called Christians. This is a Greek word. People from the household of the Roman emperor August where called 'augustianoi'. Christians where people who are belonging to the household of Christ ('christianoi' --> Christians).

Why are Christians always talking about Jesus? He is the core, the centre of Christianity. Beside that the name Christian has anything to do with Jesus. Christians are people that belongs tot Christ (Jesus).
