if a man has not had a Bar Mitzvah, and if his parents got married in a United synagogue, is he able to also get married in a united synagogue, (without having had a bar Mitvah), or would he be required to have a Bar Mitzvah first?

My Christian friend asked me in a very sincere way—Why do the Jews not practice the law of sacrifice any longer? Why do they not do animal sacrifices if the Law of Moses is still in tact and Jesus Christ was not the promised Messiah? How do I respond?

Dear Rabbi: A real question from lev: I would like to buy Warninks or Bols Advocaat (an egg-based liquor) from a Jew that did not sell his chometz on Pesach. I wrote to the LBD and Rabbi Eidlitz, but have not had any responses from them. Perhaps you might know if this product contains chometz (and would be osur) or does not (and would be mutar). Thank you. Lev

My wife (age 45) is taking hormones. This has caused her periods to become almost unnoticible and irregular. Only during intercourse on withdrawing is there a small amount of blood. Do I just count the days of niddah from the first time blood is detected? When is she considered as being post-menapause?
