The word of Elohim states,
Lev. 20:10 And the man that committeth adultery with another man’s wife, even he that committeth adultery with his neighbour’s wife, the adulterer and the adulteress shall surely be put to death.
Yet, the Christian Capitalist Libertarians at Reformed Libertarian state
“Now then, should adultery be illegal or legal? That is to ask: should adultery be responded to with aggression or with non-aggression? After all, adultery is indeed a terrible sin against God and one’s spouse, so it does certainly need a response. But is the entity of aggression (“government”) the one that should respond?
The answer, of course, depends on whether adultery is a violation of a spouse’s property right. If one’s spouse has an affair, has the adulterer aggressed against the innocent spouse? The framing of the problem immediately resolves the sometimes foggy language of whether the spouse (or children) was hurt by the deed. Of course he was hurt. So was the church, the community. Emotionally and spiritually especially. But that is not the proper question. We are hurt by each other— by our friends and colleagues and teachers and bosses and so on— all the time. But does someone have a right to be free from all types of loosely defined “hurt?” Indeed not. Thus, the proper question refers to whether an adulterer aggresses against the property of his or her spouse.
On strictly libertarian terms (which of course rejects utilitarian rationale), the most obvious answer is no, and the logical ramification is that adultery, while despicable, should indeed be legal.”
