7 / 20 August
He was born in Persia as a pagan during the reign of Emperor Constantine. He became acquainted with the Faith of Christ as a young man, abandoned paganism and was baptized. So much did Dometius love the True Faith that he left everything worldly and was tonsured a monk in a monastery near the town of Nisibis. He lived for some time among the brethren and then withdrew to a life of silence to be with an a certain elder Archmandrite Urbel, about whom it is said that he did not eat anything cooked for sixty years. The elder Urbel ordained Dometius a deacon and when he wanted to compel him to receive the rank of a priest, Dometius withdrew to an isolated mountain and settled in a cave. He attained such a high degree of perfection through fasting, prayer, all night vigils and godly-thoughts that he cured the sick. When Julian the Apostate came to those regions, he heard of Dometius and sent men, who sealed him alive in the cave along with two of his disciples. Thus, this saint of God died and took up habitation in the Kingdom of God in the year 363 A.D.
Or attained great perfection through the greatest mortification. When he firmly established himself and attained holiness in solitude, he then gradually established several monasteries and was a superb spiritual leader and teacher of many monks. Rufinus, who visited him describes Or in the following way: "In his dress [habit], he resembled an angel of God; a ninety-year old elder with a long beard, as white as snow; externally was very pleasant. His gaze shone with something super human." Often times, he saw the angels of God. He especially endeavoured never to speak an untruth. He had great temptations from the demons but overpowered them all soberly and courageously. He received Holy Communion daily. On one occasion, one of his disciples reminded him that the Feast of the Resurrection had come and that it should be celebrated. Hearing this, Or came out, raised his hands to heaven and spent three days in prayer without rest. He explained to his disciple: "For the monk, this is the celebration of the Resurrection of Christ: to elevate his mind and to unite it with God." He rested in deep old age about the year 390 A.D.
Marinus was a soldier and Asterius was a Roman senator. At the time of Emperor Gallienus, St. Marinus served as a soldier in Caesarea in Palestine. Marinus was beheaded for the sake of the Faith of Christ. Asterius, the senator, also a Christian, was present at his martyrdom. He removed his dolman and, with it, wrapped the body of the martyr, placed it on his shoulders, took it and honourably buried it. Seeing this, the pagans beheaded him also. They both died honourably for Christ about the year 260 A.D.
