Pope Hyginus

 was the pope in the Catholic Church.

Papacy
According to the Liber Pontificalis, Hyginus was a Greek by birth. Irenaeus says that the Gnostic Valentinus came to Rome in Hyginus's time, remaining there until Anicetus became pontiff (Against Heresies, III, iii). Cerdo, another Gnostic and predecessor of Marcion, also lived at Rome in the reign of Hyginus; by confessing his errors and recanting, he succeeded in obtaining readmission into the Church but eventually fell back into the heresies and was expelled from the Church. How many of these events took place during the time of Hyginus is not known.
