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.
Perayaan Quartodeciman (" empat belas") terutama menjadi peringatan sengsara dan kematian Kristus, di mana Melito berkeyakinan bahwa Kristus telah mati pada tanggal 14 sore, ketika makan malam Paskah sedang dipersiapkan.
