Non-Jews are not commanded to marry, but they are encouraged to do so, and they are forbidden to have relations with the wife of another man. Male homosexuality, incest and bestial relations are also forbidden under the same heading, even though the desires for them are very different. Jews and non-Jews are forbidden to each other, because of the different origin of their respective commandments. When these laws are observed, then human relations of all kinds are enhanced by the Divine sanction, and love increases throughout the world. Though the reasons for sexual prohibitions may be mysterious, most people if asked what laws they would make to govern the world would immediately say that on no account must illegal bloodshed be allowed to go unpunished.
Human life is a sacred trust, and can only be taken with legal sanction.
The murderer is executed by decapitation, at the sentence of the duly authorized sovereign court only. Protection is extended to the unborn, and the details of any abortion case must be closely studied according to the law. War action is subject to strict security standards, at the order of a lawful regime. It is rare for any person to take life in truly wanton circumstances, because of instinctive recognition of its value, and this recognition must be taken up to the level of reckoning which the spiritual law requires. The first man and woman transgressed the Noachide prohibition of theft by eating the fruit which had been forbidden to them, and this is still a Divine provision for non-Jews regarding all property in the hands of others.
