According to the synoptic Gospels, it would appear that on the Thursday evening of the last week of his life Jesus with his disciples entered Jerusalem in order to eat the Passover meal with them in the sacred city; if so, the wafer and the wine of the mass or the communion service then instituted by him as a memorial would be the unleavened bread and the unfermented wine of the Seder service (see Bickell, "Messe und Pascha," Leipsic, 1872).
