Saint Eumenius from the time of his youth was noted for his virtuous life. He strove to serve the One God and therefore he shunned worldly temptations. Concerned for the salvation of his soul, he distributed all his substance to the poor.
By the blessing of God Saint Eumenius was chosen as Bishop of Gortyna on the island of Crete. The saint, like a compassionate father, comforted his flock in their sorrows, and cared for the orphaned and indigent. His prayers were so strong before God that once, during a drought, he called forth abundant rain upon the earth.
Saint Eumenius wisely and zealously defended the Orthodox Faith against the Monophysite heresy. For his opposition to the heresy the saint was banished to the Thebaid, where he died in the seventh century. His body was then transferred and buried in Gortyna.
