Written during the second century AD, and only coming to light within the modern world due to the efforts of Campbell Bonner in 1940, some have argued that "Peri Pascha" ("On the Passover") is not a homily, but is based on a haggadah, which is a retelling of the works of God at Passover. The Quartodeciman celebration mainly being a commemoration of Christ's passion and death, Melito stood by the belief that Christ died on the evening of the 14th, when the Passover meal was being prepared. F. L. Cross states that Melito's treatise on Pascha is “the most important addition to Patristic literature in the present century”. The "Peri Pascha" provides an accurate description of Christian feelings towards Jews at the time and their opinion of Judaism. The text is not an all-out attack on the Jewish people; however, the Jewish people are explicitly blamed for killing Christ.
