The paralell works. Both the Qur’an and the Bible condemn homosexuality and suggest the death penalty.
Both majority Christian groups and Muslim groups do not condone/agree with that.
However, some Christians and some Muslims believe it should be implemented.
Even extremists like Westborough Baptist Church don’t advocate the death penalty for homosexuality, they suggest eternal condemnation.
Mainstream Christianity-as I see it- means us Catholics (as we are in the majority) and we advocate extreme charity to homosexuals. The only place the Bible suggests the death penalty is in Leviticus, from Greek Λευιτικός, Leuitikos, meaning “relating to the Levites”, the tribe from whom the priests were drawn. It prohibits a long list of sexual contacts and also child sacrifice. The “holiness” injunctions which give the code its name begin with the next section: penalties are imposed for the worship of Molech, consulting mediums and wizards, cursing one’s parents and engaging in unlawful sex. Priests are instructed on mourning rituals and acceptable bodily defects. Blasphemy is to be punished with death, and rules for the eating of sacrifices are set out; the calendar is explained, and rules for sabbatical and Jubilee years set out; and rules are made for oil lamps and bread in the sanctuary. The code ends by telling the Israelites they must choose between the law and prosperity on the one hand, or, on the other, horrible punishments, the worst of which will be expulsion from the land.
As Catholics, we do not isolate passages in the Bible and use them
verbatim to justify actions. Rather we rely on the
sensus plenior; that is what the whole Bible teaches, and the Old Testament is a pre-figuring of the New.
Al-Qur’an is different. It means, literally, ‘Discourse in Arabic’ or ‘The Recitation’. Muslims believe the *Qur’an *to be the book of divine guidance and direction for humanity and consider the text in its original Arabic to be the literal word of God, a miracle of perfection. Muslims believe in an utterly transcendent diety whose will is what must be done, irrespective of what we consider to be right or wrong. What is important is that you do God’s will (who reveals what God’s will is is another matter entirely). Christians believe that God does not act in an arbitrary manner. We can discern good from evil, and God does not act in an evil way. This disconnection was hi-lighted by the Pope in his infamous Regensburg lecture of 2006.
