Nectarius of Constantinople

Nectarius (... – 17 September 397) was the archbishop of Constantinople from AD 381 until his death, the successor to Saint Gregory Nazianzus.

Born at Tarsus in Cilicia of a noble family, he was widely known for his admirable character. When Gregory resigned as Archbishop of Constantinople, Nectarius was praetor of Constantinople. Preparing for a journey to Tarsus, he called on the Bishop of Tarsus, Diodore, who was attending the First Council of Constantinople (one of the ecumenical councils), to ask if he could take letters for him; his appearance and manners struck Diodorus so forcibly that he at once determined that he should be advanced as a candidate for Bishop; making an excuse of attending to some other business, he took Nectarius to see Meletius.

When the Emperor Theodosius I wanted the Bishops at the Council to suggest new candidates and reserving to himself the right of making the choice, the Bishop of Antioch put at the bottom of his list, Nectarius' name. The Emperor having read the lists, declared Nectarius to be his choice. This caused some amazement amongst the Fathers who wanted to know - who and what was this Nectarius? He was still only a catechumen. There was much astonishment at the emperor's unexpected choice, but the people of Constantinople were delighted at the news as was the whole council.

Nectarius was duly baptized and his clothes were changed for the robes of a Bishop of the Imperial city and became at once president of the Second Ecumenical Council.
