text: # Roman Catholic Diocese of Nyssa
  
  Diocese of Nyssa (Latin: Dioecesis Nyssena) is a titular see in the Eastern Orthodox Church and the Roman Catholic Church.
  
  ## Background
  
  Nyssa (Latin: Nissa) was important enough in the Roman province of Cappadocia Prima to become a suffragan of it capital's Metropolitan, the Archdiocese of Caesarea in Cappadocia (Kayseri). The earliest bishop of Nyssa whose name is known is Gregory of Nyssa, who was the bishop of Nyssa from about 372 to 394 and brother of Basil the Great, bishop of Nyssa's metropolitan see, Caesarea in Cappadocia. The bishop at the time of the Council of Ephesus in 431 was Heraclides. Musonius took part in the Robber Council of Ephesus in 449, Ioannes in the Second Council of Constantinople in 553, another Ioannes in the Third Council of Constantinople in 680, Paulus in the Trullan Council in 693, a third Ioannes in the Second Council of Nicaea in 787, and Ignatius in the Photian Council of Constantinople (879). A 10th-century bishop named Germanus is known for his ecclesiastical writings.
  
  In the 18th century, the Roman Catholic Church began appointing titular bishops of Nyssa. The Catholic see is currently vacant.
