From the Latin, meaning ‘rebirth’. The idea, but not the word, is found in the OT, in the prophet's promise of future blessings at the End (e.g. Ezek. 36: 25–6). In the NT that time is said to have arrived in the life, death, and resurrection of Jesus (Matt. 19: 28), and Christians are ‘born anew’ (1 Pet. 1: 3), ‘saved by the washing of regeneration’ (Titus 3: 5, AV; ‘through the water of rebirth’, NRSV). The ground of regeneration is the work of Christ, but it is to be apprehended through faith and sacraments.
