The Old Testament theocratic law required the death penalty for incest in Israel (Lev. 18:7-17, 29; 20:11-12). In the fullness of time (Gal. 4:4), the Messiah came and brought forth His catholic or universal church from its Jewish swaddling bands, necessitating a change in the law (Heb. 7:12). The apostles and prophets, whom God used to write the New Testament, set forth the will of Jesus Christ for His catholic church (Eph. 2:20; 3:5; 4:11).
When a man committed incest in the church of Corinth (I Cor. 5:1), Paul did not require the death penalty for him. Instead, the apostle required excommunication from the church and kingdom of God, unless the man repented (I Cor. 5:4-7). Both terrible divine judgements—execution in the Old Testament theocracy and excommunication in the New Testament church—preserve the holiness of God’s church, a reflection of the holiness of God Himself.
Leviticus 20:13 (“If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.”) required the death penalty for homosexuality in Israel. (See also Leviticus 18:22, 29). Similar to the example of incest, the New Testament does not require the death penalty for homosexuals. There were converted homosexuals in the church of Corinth (I Cor. 6:9-11)! The execution of homosexuals in Israel (the Old Testament church) is equivalent to excommunication from the New Testament church. Thus it is a contradiction in terms to speak of gay church members or gay church office bearers or gay Christians. Any churches, therefore, that receive or tolerate impenitent homosexuals as members are therefore false churches in rebellion to the will of Christ.
