Extramarital sex

The Torah prescribes the death penalty through strangulation[13] for adultery, which is defined as sex with or by a female who is already married to another man. The Torah prescribes strict liability and punishment on the male, but liability and punishment on the female only if she wasn't raped (Leviticus 20:10). As a death penalty offence, two witnesses of good character had to testify in court for the case to be even considered by the judges against either or both the male and female. (Deuteronomy 19:15, and Mishnah Sanhedrin c.4)

Jewish law technically allowed men to have polygynous relationships (one man could have many wives) -although this was the very rare exception in practice, reserved only for kings, as well as for key biblical figures whose wives could not have children - so the marital status of the man was thus legally irrelevant. If a woman, however, is unmarried, a sexual relationship, though highly immoral and sinful from the religion's point of view, is not considered to be adultery, and therefore not punishable by death, but rather is considered fornication and punished by lashing.

Adultery provisions of the Mosaic law concerned itself with protecting the paternity of the potential offspring of husbands, so that the husband’s family blood line is not adulterated and replaced with the genes of another male, thereby exterminating a husband’s family's genetic lineage from that point onwards (genocide), which was a violation of the principal term of agreement and reason for entering a matrimonial contract with his wife, and a breach by a third party (the other man) of that same contract.

Any physical punishments for any offences (sins) were in effect at the times of Judges and the Holy Temple. In rabbinic Judaism, any physical punishment is prohibited by Judaism—as no proper judicial process can be provided until the Holy Temple is rebuilt by the Messiah.

Christianity teaches that extramarital sex is immoral and sin. Scriptural foundations for this teaching are passages like 1 Corinthians 6:9–10 (KJV):

Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.

In Christian marriage, husband and wife publicly promise fidelity to each other until death. Adultery contradicts this promise. The Waldensians were accused of expressing approval of adultery in certain circumstances.[14]

Traditional interpretations of Islamic law (or Sharia) prescribe severe punishments for zina, or extramarital sex, by both men and women. Premarital sex could be punished by up to 100 lashes, while adultery is punishable by stoning. The act of sexual penetration must, however, be attested by at least four male Muslim witnesses of good character, the accused has a right to testify in court, the suspect's word or testimony is required to hold the most weight in the eyes of the judge(s), punishments are reserved to the legal authorities and the law states that false accusations are to be punished severely.[15] The former regulations also make some Muslims believe, that the process's goal was to eventually abolish the physical penalties relating to acts of fornication and adultery that were already present within many societies around the world when Islamic teachings first arose. According to this view, the principles are so rigorous in their search for evidence, that they create the near impossibility of being able to reach a verdict that goes against the suspect in any manner.[16]

Hinduism condemns extramarital sex as sin.[17] According to the Hindu Dharmashastra texts, any sexual act outside of the accepted marriage, including physical, mental, and emotional adultery, are denounced. [18]
