Saint Felix III (died March 1, 492, Rome; feast day March 1) was the pope from 483 to 492. He succeeded St. Simplicius on March 13. Felix excommunicated Acacius, patriarch of Constantinople, in 484 for publishing with the emperor Zeno a document called the Henotikon, which appeared to favour Monophysitism, a doctrine that had been denounced at the Council of Chalcedon (451). The excommunication created the 35-year Acacian Schism. Felix’ Lateran Council of March 487 fixed conditions for readmission to the church of Africans who had been rebaptized by the Vandals.
