The holy Martyr Eustathius before his baptism was an illustrious Roman general named Placidas in the days of the Emperor Trajan. While hunting in the country one day, he was converted to the Faith of Christ through the apparition of an uncommonly majestic stag, between whose antlers he saw the Cross of Christ, and through which the Lord spoke to him with a human voice. Upon returning home, he learned that his wife Tatiana had also had a vision in which she was instructed to become a Christian. They sought out the Bishop of the Christians and were baptized, Placidas receiving the name Eustathius, and Tatiana the name Theopiste; their two sons were baptized Agapius and Theopistus. The family was then subjected to such trials as Job endured. Their servants died, all their goods were stolen, and on a pilgrimage to Jerusalem they were scattered abroad, each not even knowing if the others were still alive. By the providence of God, they were united again after many years, and returned to Rome in glory. Nevertheless, when they refused to sacrifice to the idols-a public sacrifice from which no Roman general could be absent-the Emperor Hadrian, who had succeeded Trajan, had them put into a large bronze device in the shape of a bull, which was heated with fire until they died. When their holy bodies were removed, they were found to be without harm. They suffered martyrdom about the year 126.

This came to pass fifteen months before the birth of Christ, after the vision of the Angel that Zacharias, the father of the Forerunner, saw in the Temple while he executed the priest's office in the order of his course during the feast of the Tabernacles, as tradition bears witness. In this vision, the Archangel Gabriel appeared to Zacharias and said to him, "Thy prayer is heard; and thy wife Elizabeth shall bear thee a son, and thou shalt call his name John" (Luke 1:13). Knowing that Elizabeth was barren, and that both he and she were elderly, Zacharias did not believe what the Angel told him, although he had before him the example of Abraham and Sarah, of Hannah, mother of the Prophet Samuel, and of other barren women in Israel who gave birth by the power of God. Hence, he was condemned by the Archangel to remain speechless until the fulfilment of these words in their season, which also came to pass (Luke 1:7-24).

Saint Silouan was born Simeon Ivanovich Antonov in 1866 to Russian Orthodox parents who came from the village of Sovsk in Russia's Tambov region. At the age of twenty-seven he left his native Russia and came to Mount Athos, where he became a monk at the Monastery of St. Panteleimon and was given the name Silouan, the Russian version of the Biblical name Silvanus.

An ardent ascetic, he received the grace of unceasing prayer and saw Christ in a vision. After long years of spiritual trial, he acquired great humility and inner stillness. He prayed and wept for the whole world as for himself, and he put the highest value on love for enemies. Thomas Merton, a twentieth-century Catholic monk, described Silouan as “the most authentic monk of the twentieth century.” St Silouan died on September 24, 1938. He was glorified by the Ecumenical Patriarchate in 1987.

Though barely literate, he was sought out by pilgrims for his wise counsel. His writings were edited by his disciple and pupil, Archimandrite Sophrony. Father Sophrony has written the life of the saint along with a record of St. Silouan's teachings in the book Saint Silouan the Athonite.
