Why did early Christians argue over the date of Easter?In this video, we explore the Quartodeciman Controversy, a major theological debate in the 2nd century that split early Christian communities. On one side were the Quartodecimans, who celebrated Easter on the 14th of Nisan—regardless of the day of the week—following Jewish Passover tradition. On the other were those like the Roman church, who insisted Easter should always be celebrated on a Sunday.We’ll break down: • What “Quartodeciman” means • Key figures like Polycarp, Pope Anicetus, Melito, Pope Victor, Polycrates, and Irenaeus • The dating method for Dominical Pascha vs Quartodecimen Pascha, and why one method eventually wins out • The character of Quartodecimen liturgy and its lasting impact on Christian traditionThis historical dispute isn’t just about dates and calendars—it reveals how early Christians defined their identity and tradition.
