Christology
In Christian theology, Jesus is sometimes referred to as a Redeemer. This refers to the salvation he is believed to have accomplished, and is based on the metaphor of redemption, or "buying back". Although the Gospels do not use the title "Redeemer", the word "redemption" is used in several of Paul's letters. Leon Morris says that "Paul uses the concept of redemption primarily to speak of the saving significance of the death of Christ." The English word redemption means "repurchase" or "buy back", and in the Old Testament referred to the ransom of slaves (Exodus 21:8). In the New Testament the redemption word group is used to refer both to deliverance from sin and freedom from captivity.
The concept of the redeemer is used in the Book of Ruth to refer to the kinsman-redeemer, and in the Book of Isaiah to refer to God, the "Redeemer of Israel".
Many Christian churches are named "Redeemer", such as Redeemer Presbyterian Church (New York City) and the Lutheran Church of the Redeemer, Jerusalem. Other institutions which carry the name are the Roman Catholic Congregation of the Most Holy Redeemer and Redeemer University College in Ancaster, Ontario. The Christ the Redeemer statue in Rio de Janeiro is a famous landmark.
