Bishop
Saint Peter was the brother of Basil the Great and the tenth son of his parents. His upbringing was significantly influenced by his older sister Macrina, who provided him with a high education and instilled in him a love for the study of the Word of God. Thanks to her care, he achieved great virtue, and, according to Gregory of Nyssa, "in his later life he was, it seems, no less than Basil the Great in the excellence of virtues." After Basil became the bishop of Caesarea in Cappadocia, he ordained Peter as a presbyter. Later, Saint Peter was appointed bishop of Sebaste in Armenia. In this office, he attended the Second Ecumenical Council in Constantinople in 381, which condemned the heresy of Macedonius. Saint Peter passed away at the end of the 4th century.
