Bishop Peter of Sebaste/Sivas (AD 340-391)
Around 340, Peter was born the fourth son to Basil the Elder and Emmelia, the youngest of their 10
children. Peter joined the communal monastery of Basil the Great on the family’s property in Pontus. In 362, when Basil returned to Caesarea to serve the church, Peter became the spiritual leader of the Pontus monastery. Around 380, Basil the Great ordained Peter as bishop of Sebaste, where he served for around eleven years, from 380 to 391. Along with his brother Gregory of Nyssa, Peter participated in Constantinople’s Ecumenical Church Council in 381 and assisted in the writing of the final version of the Nicene Creed. He died in Sebaste in 391 at the age of fifty-one.
