The custom of observing Easter on the 14th day of Nisan (the day of the Jewish Passover), whatever the day of the week. The tradition was rooted in Asia Minor. When St Polycarp, Bp. of Smyrna, visited Rome c.155, Pope Anicetus refused to change his own practice but had no scruples about Polycarp's continuing to follow his custom. A more rigid line was taken by Victor I (189–98), who tried to suppress Quartodecimanism. The Quartodecimans later organized themselves as a separate Church, surviving until the 5th century.
