Although Jesus' Last Supper probably took place on the night before Passover (as in John) rather than on the first night of Passover itself (as in the Synoptics), it contained elements strongly marked by the Jewish institution of the Passover seder (fixed order of service) and haggadah (ritual retelling of the exodus events). These elements were not, as some scholars of Judaism have recently argued, post-70 CE developments. Rather, evidence from Jubilees, Philo, and the NT itself indicates that seder and haggadah already existed in some form in the pre-70 period.
