Peri Pascha ("Concerning the Passover") is a 2nd century document from Melito of Sardis that was assembled from surviving fragments in the 1930s, and translated into English in the 1940s.
Prior to the recovery of the full text less the opening folio among the Bodmer Papyri the order in which the fragments had been assembled was a possible reconstruction.[1] It is clear from Eusebius that Melito celebrates Passover on the fourteenth of Nisan, rather than the Sunday following,[2] hence he was a Quartodeciman.
In this homily, Melito formulated the charge of deicide, namely that Jews were responsible for the crucifixion of Jesus. He proclaimed that "God has been murdered; the king of Israel has been slain by an Israelite hand." Some believe his preaching later inspired pogroms against the Jews.[3]
Other scholars have questioned this conclusion, and do not consider that Melito encouraged any form of anti-semitism, especially since he advocated Quartodeciman beliefs.
