Quartodeciman Controversy

Irenaeus took part in the Quartodeciman Controversy. When Victor I of Rome tried to force a universal practice of fasting until Easter to supersede the Jewish practice and prevent Christians from partaking of the Passover, Polycrates who led the Churches of Asia Minor continued to hold old traditions of the paschal feast. For this reason Victor I wanted to excommunicate Polycrates and his supporters, but this was a step too far for Irenaeus and other bishops.
