The term “Christ Jesus” is the same thing as saying, “President Obama.” One word is a title, the other is a name.
Christ, technically speaking, isn’t Jesus’ name; it’s His title. The Greek Christos and the Hebrew Meshiach both mean the same thing—the ‘anointed One’ – i.e., the person whom God has chosen for a special role. Jesus is the Christ, He’s God’s specially chosen One who would redeem God’s people and bring in God’s kingdom.
