The name “Jesus” means, “God saves”, conveying the Son’s mission while on earth as a man. He was sent to redeem us, and did this by dying for our sins on the Cross, rising from the dead and thus bringing us to new life, and by his teaching and handing on of the truth of the Catholic faith (contained in the content of divine revelation) to the Apostles. This is also signified by the title “Good Shepherd”, as he looks after his sheep and lays down his life for them.
The title “Christ” is synonymous with “Messiah”, a term that means “anointed” or “chosen”. This is inherited from the Old Covenant, where a Messiah was promised to come and save God’s people.
The Son is also given the title “Lord”, or “kyrios” in Greek. This indicates divine sovereignty, but it is a different concept of lordship from the prevailing human idea. Jesus came not to be served but to serve, and is thus rightly called the “Servant King”.
