"His popularity in Ukraine and elsewhere was due to his Gospel and the belief that he was taken bodily into heaven upon his repose. On this day, worshippers at the site of his tomb at Ephesus are enveloped with bright particles that rise in the air as a result of a gentle breeze and these particles are miracle-working. On the island of Patmos where St John wrote the Book of Revelation, there is enshrined the Kozak martyr, St Pachomius."[3]

(Elder Michael I The Confessor, 1871-1934). An outstanding monastery spiritual director and a leading father during the height of Valaam's blossoming. Elder Michael showed his integrity and genuineness when trouble struck in the twenties, with the forced installation of the Western secular calendar into Church life, which had not changed since ancient Byzantine times. He became a stalwart confessor of ecclesiastical firmness to the end and died as a hero in battle after being tormented by years of banishment, exile and mockery. Fr. Michael came to Valaam at a young age and his two brothers followed him, one a poet, and the other a musician, and they became outstanding monks. After visiting the Holy Land, Mt. Athos, Optina, and other centers of living Orthodoxy, Fr. Michael was able to widen his spiritual vision. He became a God bearing Elder and enabled his monks to be zealots for Orthodoxy at a time when apostasy began to encroach upon the Orthodox Church from within. In this sense, he became a carrier of the apostolic gift of Prophecy as is spoken of by St. Paul. A man ahead of his time, he is a guiding light for us and for Russia today.[23]
