CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 450–453

450 From the beginning of Christian history, the assertion of Christ's lordship over the world and over history has implicitly recognized that man should not submit his personal freedom in an absolute manner to any earthly power, but only to God the Father and the Lord Jesus Christ: Caesar is not "the Lord". "The Church. . . believes that the key, the center and the purpose of the whole of man's history is to be found in its Lord and Master."
451 Christian prayer is characterized by the title "Lord", whether in the invitation to prayer ("The Lord be with you"), its conclusion ("through Christ our Lord") or the exclamation full of trust and hope: Maran atha ("Our Lord, come!") or Marana tha ("Come, Lord!") - "Amen Come Lord Jesus!"
452 The name Jesus means "God saves". The child born of the Virgin Mary is called Jesus, "for he will save his people from their sins" (Mt 1:21): "there is no other name under heaven given among men by which we must be saved" (Acts 4:12).
453 The title "Christ" means "Anointed One" (Messiah). Jesus is the Christ, for "God anointed Jesus of Nazareth with the Holy Spirit and with power" (Acts 10:38). He was the one "who is to come" (Lk 7:19), the object of "the hope of Israel" (Acts 28:20).
