Proclus, Archbishop of Constantinople
Saint Proclus lived during the reign of Saint Theodosius the Younger. A disciple and scribe of Saint John Chrysostom, he was ordained Bishop of Cyzicus about the year 426, but because the people there unlawfully elected another bishop before his arrival, he remained in Constantinople. In 429, Nestorius, who had been Archbishop of Constantinople for about a year, and had already begun his blasphemous teaching that it is wrong to call the holy Virgin "Theotokos," invited Bishop Proclus to give a sermon on one of the feasts of our Lady, which he did, openly defending in Nestorius' presence the name "Theotokos," that is, "Mother of God." Saint Proclus was elevated to the throne of Archbishop of Constantinople in 434. It was he who persuaded Emperor Theodosius the Younger and his holy sister Pulcheria to have the most sacred relics of his godly teacher Saint John Chrysostom brought back from Comana, and triumphantly received them upon their return to the imperial city (see Jan. 27 and Nov. 13). He reposed in peace in 447.
