St Seraphim is
unknown to the church Synaxaristes but is documented in a service in Aigina in 1828, conducted by Bishop Talantios Neophytos Metaxas, that was later published in Athens in 1855 and revised in 1885.
His parents were respectable and raised Seraphim
in a pious life. From a young age, he had a calling to the monastic life and left the world early to pursue his ascetical vocation living in a cave at the Prophet Elias on Mount Karkara. There he built a chapel dedicated to the Saviour and spent his time in ascetism. However, he had frequent visitations from family and friends so he left this beloved cave and fled to the monastery of the Holy Unmercenaries Anargyroi.
He did not spend much time at this monastery for the same reasons and left for the Monastery of the Transfiguration of the Savior, located between Thebes and Evia. At this monastery, his ascetical works made him shone as a spiritual star and the abbot of this monastery quickly made him a monk and this is where he was given the name "Seraphim".
