Saint Proclus was a disciple of Saint John Chrysostom. He was born in Constantinople around 390 AD and was ordained Bishop of Cyzicus in 426 AD. However, he was unable to enter his diocese due to a dispute between the Patriarch of Constantinople who ordained him and the people of Cyzicus. He remained in Constantinople, moving between its churches, preaching like his teacher, until he was chosen Patriarch of Constantinople in 434 AD. Proclus was distinguished by his sobriety, humility and moderation.

He was known for his courage and adherence to the true faith and his defense of it before and after his accession to the patriarchate. He had a position with Nestorius that history has preserved. In the year 429 AD, he gave a sermon on the occasion of Christmas in the presence of Nestorius, in which he praised the Virgin Mary and called her “Mother of God,” despite Nestorius’ objection.

As patriarch, Proclus was keen on the unity of the church and devoted himself to dealing with the consequences of the Nestorian heresy. He is credited with transferring the relics of Saint John Chrysostom from Comana in Pontus (in present-day Turkey) to Constantinople on January 27, 438 AD.

In his days the Trisagion (Holy God, Holy Mighty, Holy Immortal, have mercy on us) was introduced into the Divine Liturgy.

In 447 AD, the country was struck by a series of earthquakes that left thousands of people dead and devastated. Proclus embraced the victims and offered them whatever assistance he could. In the same year, Proclus passed away in the Lord, after leading the church for twelve years. The Holy Church commemorates him on the twentieth of November.
