Christian

the name given by the Greeks or Romans, probably in reproach, to
the followers of Jesus. It was first used at Antioch. The names
by which the disciples were known among themselves were
"brethren," "the faithful," "elect," "saints," "believers." But
as distinguishing them from the multitude without, the name
"Christian" came into use, and was universally accepted. This
name occurs but three times in the New Testament (Acts 11:26;
26:28; 1 Pet. 4:16).
