Christ founded one Church.
Now I could be mistaken on how the word 'Christian' came to be, so any help would be appreciated..
The word Christian was applied as a nickname for the followers of Jesus by people who were not 'Christian'.
If you read the New Testament thru the eyes of someone who didn't have any pre conceived knowledge of religion, you would clearly see Jesus Christ started a Church and made Peter His first leader before He died.
St. Evodius is thought to have first used the name Christian. He was the first bishop of Antioch....
