Jewish and Christian leaders, both in history and in the present day, offer considerable objection to Christian observance of the Passover. It seems that neither official Judaism nor official Christianity is very tolerant of Christians who confuse and confound the clear delineation between these two faiths by attempting to observe the traditional Passover, with or without including the Calvary experience.
Most Christian objection to Passover observance is based on ecclesiastical anti-Judaism that developed after the Church’s first century. Before the Church fully opened the door to the Gentiles at the Jerusalem Council, the vast majority of its communicants were Jews; therefore, there was no question as to whether Christians should observe Passover. Its celebration was a significant part of the biblical heritage upon which the early Jewish leaders of the Church had founded a faith and polity that recognized Yeshua (Jesus) as the fulfillment of the Messianic expectations of His people and as the Savior of the world.
As Gentiles came to prominence in the Church, they were influenced by traditions which they had brought with them and by pressures from the political powers of the day to disassociate themselves from the Jews and things “Jewish.” At the same time a controversy raged in the Church over whether complete obedience to the Law of Moses was essential to salvation in addition to faith in Jesus. Of particular concern was the practice of circumcision, whether it should be physically enforced on new converts to this Judeo-Christianity or whether the circumcision of the heart that God had described to Moses, Jeremiah, and Paul was sufficient without the physical procedure.
