Saint Anatolius was a priest of Alexandria. After the Robber Council of 449, the heretical Patriarch Dioscorus of Alexandria consecrated Anatolius as Patriarch of Constantinople, thinking that Anatolius would support his views. But Anatolius upheld Orthodoxy and Dioscorus was deposed soon after. As patriarch, he condemned Nestorius, Eutyches, and Dioscorus at the Council of Chalcedon in 451. He reposed in the year 458. His feast is celebrated on July 3.
