Nope! The people who followed the Savior Jesus Christ, were known as "Christians":
and when he found him, he brought him to Antioch. So for a whole year Barnabas and Saul met with the church and taught great numbers of people. The disciples were called Christians first at Antioch. (Acts 11:26)
Then Agrippa said to Paul, Do you think that in such a short time you can persuade me to be a Christian? (Acts 26:28)
However, if you suffer as a Christian, do not be ashamed, but praise God that you bear that name. (I Peter 4:16)
The followers of Christ were called Christians and it was after the first century when the faith Christians held began to be called "catholic", because it was recognized as a universal faith that ALL those who followed Christ held to the same faith in Him as Savior, Lord and God.
at first, yes, but we were discussing what they were known as in subsequent years...in the year 234 they were known as Catholics......and Catholics are Christians
