The article tells us that there are five texts in this Sahidic Coptic codex. We already knew it contains Jonah and 1 Peter. The article adds that it also has excerpts from 2 Maccabees and (the headline text) a copy of Melito's homily on Passover (Peri Pascha). The fifth text, unmentioned, is an otherwise unknown Easter sermon. For additional detains see here.
