Although recent scholarship suggests that the Seder did not formally become part of the Passover celebration until after the destruction of the Temple in 70 C.E., important rituals invariably evolve from long-standing cultural practice. See Jonathan Klawans, “Was Jesus’ Last Supper a Seder?” Bible Review, October 2001; B. Bokser, The Origins of the Seder: The Passover Rite and Early Rabbinic Judaism (Berkeley: University of Cailfornia, 1984); and Eliezer Segal, “The Seder as a Living Tradition,” Jewish Star (Calgary, Canada), March 11, 1988.
