Pope Anicetus

 was the pope of the Catholic Church.

Papacy
According to Irenaeus, it was during his pontificate that the aged Polycarp of Smyrna, a disciple of John the Evangelist, visited Rome to discuss the celebration of Passover with Anicetus. Polycarp and his Church of Smyrna celebrated the crucifixion on the fourteenth day of Nisan, which coincides with Pesach (or Passover) regardless of which day of the week upon this date fell, while the Roman Church celebrated the Pasch on Sunday—the weekday of Jesus' resurrection. The two did not agree on a common date, but Anicetus conceded to St. Polycarp and the Church of Smyrna the ability to retain the date to which they were accustomed. The controversy was to grow heated in the following centuries.
