Miracles and Healings
Parthenios is venerated above all as a healer and an exorcist. The accounts of his life relate that he healed every manner of illness through prayer and was especially powerful over evil spirits. Among the miracles ascribed to him, the tradition records that he restored a man's dislocated eye and healed a woman afflicted with a fatal cancer through the sign of the cross.
A widely repeated episode concerns one of his exorcisms: when commanding an unclean spirit to depart from a possessed man, he is said to have invited the demon to come and dwell in him instead, whereupon the spirit fled, unable to enter what the tradition describes as the house of God. On account of his reputation for healing, and particularly the account of the woman cured of a tumor, he is invoked in popular Greek devotion by those suffering from cancer.
