Киево-Печерская лавра
Being a monk at Kiev Pechersk Lavra, he left to preach Gospel to idol-worshippers Viatichi. He there performed numerous miracles. Impressed by his powers and rendered receptive by his preaching, the heathens began to convert and accept baptism. Priests of Viatichi, furious over the destruction of their idols, decapitated Kuksha and his pupil. On the day of Kuksha's death, his spiritual father Saint Pimen the Faster stood in the middle of the monastery church and loudly proclaimed: "Our brother Kuksha has been killed this day". Saint Pimen died the same day.
