Saint Frumentius was still a child when his uncle, a Christian philosopher of Tyre in Phoenicia, took him and his brother Edesius on a voyage to Ethiopia. In the course of their voyage the vessel anchored at a certain port, and the barbarians of that country slew with the sword all the crew and passengers, except the two children.
Because of their youth and beauty they were taken to the king at Axuma, who, charmed with the wit and sprightliness of the two boys, took special care of their education, and later made Edesius his cup-bearer and Frumentius, who was a little older, his treasurer and secretary of state. The king, on his deathbed, thanked them for their services and in reward gave them their liberty.
After his death the queen begged them to remain at court and assist her in the government of the state until the young prince came of age; this they did, using their influence to spread Christianity. When the young king reached his majority, Edesius desired to return to Tyre, and Frumentius accompanied him as far as Alexandria. With the blessing of Saint Athanasius, Frumentius was elevated to become Bishop of Abyssinia and he returned to that country, which had sheltered him from his childhood.
After he returned from his consecration, Saint Frumentius began to perform miracles, bringing many people to the Church. The emperor said to him, “You have lived among us for many years, yet we never saw you perform such wonders. Why is it that you do so now?” The saint replied, “This has nothing to do with me, but is due to the grace of the priesthood.” Then the emperor and many of his subjects received holy Baptism.
Having accomplished the apostolic task of converting the Abyssinian nation to Christ, Saint Frumentius zealously and fruitfully guided the Church entrusted him by God for many years. Vested with this sacred character he gained great numbers to the Faith by his discourses and miracles, and the entire nation embraced Christianity with its young king, thus fulfilling a famous prophecy of Isaiah, uttered 800 years before Christ. (Isaiah 45:14) Saint Frumentius continued to feed and defend his flock until it pleased the Supreme Pastor to call him home and reward his fidelity and labors, in about the year 383.
