  redemption
       n 1: (Christianity) the act of delivering from sin or saving from
            evil [syn: salvation]
       2: repayment of the principal amount of a debt or security at
          or before maturity (as when a corporation repurchases its
          own stock)
       3: the act of purchasing back something previously sold [syn: repurchase,
           buyback]
  Redemption
     the purchase back of something that had been lost, by the
     payment of a ransom. The Greek word so rendered is
     _apolutrosis_, a word occurring nine times in Scripture, and
     always with the idea of a ransom or price paid, i.e., redemption
     by a lutron (see Matt. 20:28; Mark 10:45). There are instances
     in the LXX. Version of the Old Testament of the use of _lutron_
     in man's relation to man (Lev. 19:20; 25:51; Ex. 21:30; Num.
     35:31, 32; Isa. 45:13; Prov. 6:35), and in the same sense of
     man's relation to God (Num. 3:49; 18:15).
       There are many passages in the New Testament which represent
     Christ's sufferings under the idea of a ransom or price, and the
     result thereby secured is a purchase or redemption (comp. Acts
     20:28; 1 Cor. 6:19, 20; Gal. 3:13; 4:4, 5; Eph. 1:7; Col. 1:14;
     1 Tim. 2:5, 6; Titus 2:14; Heb. 9:12; 1 Pet. 1:18, 19; Rev.
     5:9). The idea running through all these texts, however various
     their reference, is that of payment made for our redemption. The
     debt against us is not viewed as simply cancelled, but is fully
     paid. Christ's blood or life, which he surrendered for them, is
     the "ransom" by which the deliverance of his people from the
     servitude of sin and from its penal consequences is secured. It
     is the plain doctrine of Scripture that "Christ saves us neither
     by the mere exercise of power, nor by his doctrine, nor by his
     example, nor by the moral influence which he exerted, nor by any
     subjective influence on his people, whether natural or mystical,
     but as a satisfaction to divine justice, as an expiation for
     sin, and as a ransom from the curse and authority of the law,
     thus reconciling us to God by making it consistent with his
     perfection to exercise mercy toward sinners" (Hodge's Systematic
     Theology).
