apocatastasis (from Greek, ‘reestablishment’), the restoration of all souls, including Satan’s and his minions’, in the kingdom of God. God’s goodness will triumph over evil, and through a process of spiritual education souls will be brought to repentance and made fit for divine life. The theory originates with Origen but was also held by Gregory of Nyssa. In modern times F. D. Maurice (1805–72) and Karl Barth (1886– 1968) held this position. See also GREGORY OF NYSSA , ORIGE.
