The use of “Christ,” meaning “the anointed,” the “Messiah,” as a proper name became common after the death of our Lord, particularly in the writings of St. Paul.  It might be used either before or after the name “Jesus.”  Its use by St. Paul declared the Apostle’s belief and affirmation of the divinity of Jesus.

However, the word Kyrios in Greek is a translation of the Aramaic equivalent of “the prophesied king.”  Thus, Jesus fulfilled in His Incarnation the promise made to Abraham, as given in the genealogy found in the first chapter of St. Matthew’s Gospel.

Vatican II spoke of Christ:  “He who is the image of the invisible God is Himself the perfect man.  To the sons of Adam He restores the divine likeness which had been disfigured from the first sin onward.  Since human nature as He assumed it was not annulled, by the very fact it has been raised up to a divine dignity in our respect too.  For by His Incarnation the Son of God has united Himself in some fashion with every human.  He worked with human hands.  He thought with a human mind, acted by human choice, and loved with a human heart.  Born of the Virgin Mary, He has truly been made one of us, like us in all things except sin.”  (8:5)
