LEV248 Unlike general society, which may change its value system from generation to generation (fifty years ago, for example, nearly 100% of surveyed Americans thought homosexuality was immoral, while today the percentage is far less), Jewish values do not change from generation to generation, since they are divinely established and human nature remains the same, even as human values are ephemeral. The Torah clearly states that homosexual activity is morally wrong, calling it an abomination [this verse]. In addition, this sin is so severe that the penalty is death (Leviticus 20:13). It should be noted that one may not confuse the Jewish attitude toward homosexual behavior with a Jewish attitude to the homosexual. In Judaism, one can hate the sin but not the sinner (See chapter "Hate and Revenge"). As the Talmud notes according to one interpretation (Berachot 10a), based on the verse in Psalms (Psalms 104:35), one should pray for the end of sin, not for the end of perennial sinners. Sinners are still considered part of the Jewish community (Sanhedrin 44a)... In fact, if it can be proven in the future that specific homosexual behavior is due to a sickness and is uncontrollable, rather than is a tendency, urge, and a lifestyle made by choice, then those who engage in this type of homosexual behavior would be in the Jewish category of ones and would not be morally responsible. Similarly, a shoplifter who was a kleptomaniac and psychologically deemed not in control is not looked upon as a sinner unless the immoral act is made out of free choice. However, homosexuality has not yet been proven to be an illness.
