Orientales Omnes Ecclesias §47

⁴⁷ The first of their number to come to our mind is the holy pontiff Josaphat Kuntzevitch, whose unconquerable fortitude we have briefly praised above. When he was murderously sought out by abandoned enemies of the Catholic name, he freely offered himself to the murderers, and gave himself as a victim to bring about as soon as possible the return of his dissident brethren. He was the outstanding martyr for Catholic faith and unity at that period, but not the only one; not a few both of the clergy and the laity received the same palm of victory after him; some were slain with the sword, some atrociously flogged to death, some drowned in the Dnieper, so passing from their triumph over death to heaven.
