The Christian teachings on sexual ethics from Christian sacred texts teach adherents that there is strictly to be no adultery; “You shall not commit adultery” (Exodus 20:14). Each Christian denomination teaches that divorce is a sin, “everyone who divorces his wife makes her commit adultery, whoever marries a divorced woman commits adultery” (Mt 5:31-32). Likewise, each denomination is also opposed to remarriage, viewing it as betraying God’s wish; “whoever divorces his wife and marries another commits adultery” (Mk 10:12). Each Christian denomination teaches that unfaithfulness is not permitted within the Christian Church and is a great sin against God, teaching Christians to ‘love your wife just as Jesus loved the church’ (Ephesians 5:31-2). Adultery in all forms is seen as an immoral sin from all denominations.
The Christian teaching on premarital sexuality differs between Christian denominations. The Catholic Church and Orthodox Churches emphasise chastity as essential, stating that there should be no sexual activity outside or before marriage, however the both churches acknowledge human mistake and view chastity as a gradual process. Evangelistic Protestant Churches have a strict no sex before or outside marriage view,
