D] The Passover Controversy.

As the Church of Rome began to celebrate the Eucharist on Easter day instead of celebrating the Passover, Polycarp, Bishop of the Church of Smyrna, and Pope Anicetus, Bishop of the Church of Rome, disputed over the Passover around 155 A.D.
Polycarp emphasized that the Passover was a traditional custom handed down from Jesus, saying that he had been celebrating the Passover every year, together with John-one of Jesus' disciples-and many other apostles.
In this dispute, however, they failed to persuade each other.

Afterward, around 197 A.D., Victor the Bishop of Rome insisted that the churches should adopt the Roman practice of celebrating Easter instead of the Passover, and compelled all the churches to accept the Dominical Rule.
The churches in the West agreed to follow the Dominical Rule, but the churches in the East which were the foundation of the Christian Church greatly opposed his insistence.
Especially, Polycrates, Bishop of the Church of Ephesus, sent a letter to Victor, in which he strongly emphasized that the Passover should be celebrated.
Through the letter which Polycrates sent to Victor at that time, we can guess the situation where the truth gradually started to become perverted after the Early Church.

- Eusebius Pamphilus, Eusebius' Ecclesiastical History, pp.208~209 -
[All these observed the fourteenth day of the Passover according to the gospel, deviating in no respect, but following the rule of faith. ... and my relatives always observed the day when the people (i.c. the Jews) threw away the leaven.]

When Victor received this letter, he planned to excommunicate all the churches in Asia and the nearby churches by accusing them of being "non-Orthodox."
However, he could not achieve his plan because of objections from many churches around him.

The Eastern Church continuously celebrated the Passover according to the teachings of Jesus and the traditions of the apostles.
This is evidence that the Passover was not abolished even in the New Testament.
The Passover is the feast of life which Jesus established with bread and wine, in order to fulfill His words: "Unless you eat the flesh of the Son of Man and drink his blood, you have no life in you" (Jn 6:53).
