A Serbian hierarch in Calvinist Transylvania
Savva governed the Orthodox Church of Transylvania during a period when the Reformed (Calvinist) authorities of the principality pressed the Romanian and Serbian Orthodox population toward the Reformed confession. His response was both pastoral and practical: he established a printing press and issued service books, instructional manuals for clergy and laity, and a catechism, equipping his flock to hold to the Orthodox faith.
His resistance to conversion efforts eventually cost him his see. He was removed on false accusations and, in 1680, imprisoned at Blaj, where the sources relate that he suffered cruel torture over roughly three years before being released, broken in body.
