During the Seder on Passover, there is an obligation to drink four ceremonial cups of wine while reciting the Haggadah. It has been assumed as the source of the wine-drinking ritual at communion in some Christian groups. During Purim, there is an obligation to become intoxicated; however, as with many other decrees, this has been avoided in many communities by allowing sleep during the day as a replacement.The Babylonian Talmud says in Megillah 7b that "Rava said: A person is obligated to become intoxicated on Purim until he is unaware of the difference between 'Cursed be Haman' and 'Blessed be Mordechai.'" This is taken to mean that on the Jewish festival of Purim one is commanded to drink alcohol to the point of intoxication. See Yanki Tauber: Are Jews actually supposed to get drunk on Purim? Chabad.org (referring to the Talmudic tractate Megillah (7b)).
