But if one of you suffers for being a Christian, let him not be ashamed; but let him glorify God in this matter.
a Christian -- Many believe this was originally a term of derision, but see note at. Acts 11:26; Acts 26:28. It is only used three times in the NT. It meant “little Christ” (i.e. Christianos). It became the common designation for believers by the middle of the first century (i.e. Tacitus, Ann. 15:44). Most likely the term used by Gentiles to differentiate the believers from orthodox Jews. - WG
