Christ is a title, not his name. It means the anointed one, or The Messiah. Those who worship or believe that a Messiah may arrive may have used this title before to describe him. So it is possible that people worshiped a Christ, a title given to a man to be called The Messiah. The followers of Jesus used the title of Christ to describe him. IIRC the religion was originally called "The Way".

Be sure to look at all the different views people have of Jesus. Yes Peter is correct in saying Jesus is also known as Isa to the Muslims.
