Christ (Colossians 1:1)

Paul is an apostle of Jesus Christ. Is Christ Jesus' last name? Many people think of Christ as part of His name but it is actually His title.

Christ literally means anointed. Jesus is God's Anointed One. "The word 'Christ' affirms that Jesus has been specially commissioned by the Father to an important office. In the OT the word 'anointed' is closely linked with two offices--that of king and that of high priest."1
