Jesus ate His last Passover meal in the “Upper Room” with His followers (Mark 14:15; Luke 22:12). Throughout the Apostolic Age, the ancient Church of God celebrated this event from the perspective of the night of this Last Supper. The symbols of this New Passover consisted of unleavened bread and wine (symbolic of Jesus’ broken body and shed blood). Jesus introduced these New Covenant symbols at the beginning of Nisan 14, the Tuesday evening before His death. The first-century order of service at the New Passover included a foot-washing ceremony followed by the ritual partaking of unleavened bread and wine. Early Christians continued to keep the New Passover, annually, at the beginning of the fourteenth day of the first month, called Abib anciently and Nisan in Jesus’ day, determined by the priestly lunisolar calendar. We call it the New Passover or Christian Passover herein only to distinguish it from the Passover of the Jews, which was observed at the beginning of Nisan 15. The first Christians presumably simply referred to it as Passover. It’s important to note that the followers of Jesus kept the very first Christian Passover on a Tuesday evening, a full twenty-four hours before the traditional Jewish Passover on Wednesday night. The Christian Passover was set as an annual event, at the beginning of the fourteenth of Nisan, observed at the hour set by Jesus. It is vitally important that we understand the significance of the Passover.
