Today is the feast of St. Josaphat Kuncewicz , "an Eastern Rite bishop . . . held up as a martyr to church unity because he died trying to bring part of the Orthodox church into union with Rome."
"His favourite pious exercise was to make a poklony (i.e. a reverence) in which the head touches the ground)" while saying the Jesus Prayer:  Panie Jezu Chryste, Synu Boga, zmi?uj si? nade mn?, grzesznikiem.
"On 12 November 1623, an axe-stroke and a bullet brought Josaphat his martyr's crown.
"His bloody body was dragged to the river and thrown in, along with the body of a dog who had tried to protect him. . . . in 1867 Josaphat became the first saint of the Eastern church to be formally canonized by Rome."
