Saint Eustratius, originally from Kiev, became a monk of the Pechersk Monastery, donning the full armor of God. He distributed his possessions to the poor and began to strive in prayer and fasting, imitating Christ. During the invasion of the Polovtsians led by Bonyak, he was captured and sold into Greek lands, where, despite threats, he strengthened other captives in faith.
When the captives died of hunger, Eustratius remained alive due to his abstinence. He was crucified by a wicked Jew and his friends, but he thanked God for the opportunity to suffer for Christ. The saint rejected offers of salvation and awaited eternal life with hope.
After his martyrdom, his body was thrown into the sea, but miraculously it was found in a cave. The saint's prophecy about the punishment of the Jews was fulfilled when the king expelled them from his lands, and the eparch who facilitated the persecutions was executed. Many Jews, seeing the miracles that occurred after his death, believed in Christ.
