Eusebius and Passover.

The Catholic writer Eusebius recorded that Polycrates of Ephesus, around 195 A.D. wrote the following to the Roman Bishop Victor who, as the previous writing showed, wanted all who professed Christ to change Passover from the 14th of Nisan to Sunday:

We observe the exact day; neither adding, nor taking away. For in Asia also great lights have fallen asleep, which shall rise again on the day of the Lord’s coming, when he shall come with glory from heaven, and shall seek out all the saints. Among these are Philip, one of the twelve apostles, who fell asleep in Hierapolis; and his two aged virgin daughters, and another daughter, who lived in the Holy Spirit and now rests at Ephesus; and, moreover, John, who was both a witness and a teacher, who reclined upon the bosom of the Lord, and, being a priest, wore the sacerdotal plate. He fell asleep at Ephesus. And Polycarp in Smyrna, who was a bishop and martyr; and Thraseas, bishop and martyr from Eumenia, who fell asleep in Smyrna. Why need I mention the bishop and martyr Sagaris who fell asleep in Laodicea, or the blessed Papirius, or Melito, the Eunuch who lived altogether in the Holy Spirit, and who lies in Sardis, awaiting the episcopate from heaven, when he shall rise from the dead? All these observed the fourteenth day of the passover according to the Gospel, deviating in no respect, but following the rule of faith. And I also, Polycrates, the least of you all, do according to the tradition of my relatives, some of whom I have closely followed. For seven of my relatives were bishops; and I am the eighth. And my relatives always observed the day when the people put away the leaven. I, therefore, brethren, who have lived sixty-five years in the Lord, and have met with the brethren throughout the world, and have gone through every Holy Scripture, am not affrighted by terrifying words. For those greater than I have said ’ We ought to obey God rather than man’ (Eusebius. Church History, Book V, Chapter 24. Translated by Arthur Cushman McGiffert.

Notice that Polycrates said that he and the other early church leaders (like the Apostles Philip and John, and their successors like Polycarp, Thraseas, Eumenia, Sagaris, Papirius, Melito) would not deviate from the Bible, and that they knew the Bible taught them to keep the Passover on the correct date, and not on a Sunday. Also notice that they always observed the day when the people put away the leaven. Polycrates also reminded the Roman bishop that true followers of Christ "obey God rather than men"
