A. Definition
Christianity (Χριστιανισμός, Christianismós) was a monotheistic religious system ( Monotheism) which emerged from Judaism in the procuratorial province of Judaea during the 1st cent. AD. At Christianity's centre were the life and mission of Jesus of Nazareth, whose adherents regarded him as the ‘Messiah’, or God's ‘anointed’ (Χριστός, Christós), and as his son, wholly participating in the nature of God.
