On the anniversary of the arrival of the Russian missionaries in Alaska (1794), we remember the New Martyrs St Peter the Aleut, Protomartyr of America, and St Juvenal.
From a bio on St. Herman of Alaska (emphasis added):
Saint Herman of Alaska was born in 1756 or 1760 in Serpukhov in the Moscow Diocese of Russia. He took the name Herman when tonsured a monk in the Trinity-Sergius Hermitage, near the Gulf of Finland, about 10 miles from St. Petersburg. He then transferred to the Valaam Monastery on the islands of Lake Ladoga. He was allowed later to live in the wilderness, a hermit alone in prayer, returning to the monastery only for the services of holy days.
In 1793, Father Herman, with Father (later, St.) Juvenaly and others, were chosen to do missionary work in Alaska. By zeal and the grace of God, they brought to the Faith several thousands of Native Alaskans. However, as time went by, the missionary party was slowly cut down. Some drowned in a ship at sea. Father Juvenaly was martyred at the hands of fearful Alaskans. Eventually, only Father Herman alone, of the original party, remained.
Father Herman settled on Spruce Island, and named it, “New Valaam,” in honor of his beloved Valaam Monastery. He dug a cave out of the ground with nothing but his hands, and lived there until a cell could be built, in which he then lived until his death. He grew his own food, not only for himself but for all he cared for, digging the earth, planting, carrying heavy loads of seaweed to fertilize the earth. He was a great ascetic; he was always barefoot even in these lands of the far North, and wore only a deerskin smock, a podrasnik and a patched rassa (inner and outer cassock), and his klobuk (monastic hat). He slept very little, and only on a wooden bench with no cushion, used bricks for a pillow, and covered himself with no blankets, but only a board.
He advocated for and defended the Aleuts against sometimes oppressive authorities. He cared lovingly and sacrificially for all who came to him, counseling and teaching them, and tirelessly nursing the sick. He especially loved children, for whom he often baked biscuits and cookies.
He was a great and compelling teacher, not only to Aleuts but also to highly educated and “free-thinking” Russians and Europeans who happened to travel there, and this humble monk humbled these “great ones” by his knowledge and wisdom, converting many to the true Faith. Often Aleuts were so captivated that they stayed up with him all night, not leaving until dawn.
The elder was given great spiritual gifts by God. He often foreknew the future, telling people of events that would happen many years later, and which were shown to have come true. By his prayers, God averted forest fires from crossing a line Father Herman made, and stopped a flood from rising past the position where Father Herman had placed an icon of the Mother of God and prayed.
Father Herman reposed in the Lord in his sleep on the 25th day of December (December 12th on the ancient Calendar of the Church), in 1837. He continued to work miracles after his death, answering the prayers of the faithful in intercession for them before God.
Holy St. Herman, pray to God for us.
From a short bio on St. Juvenaly (emphasis added):
St. Juvenaly was the protomartyr (first martyr) of the Americas, dying as a martyr at the hands of natives in Alaska in 1796. He was born in 1761 in Ekaterinburg, in the Ural Mountains of Russia, and was named Jacob Govouchkin. When he was tonsured a monk, he took the name Juvenaly, after St. Juvenal, Patriarch of Jerusalem in the fifth century. He was ordained a hieromonk (a priest/monk), and lived for some time in the Konyavesky Monastery on Lake Ladoga in Russian Finland.
In 1793, Father Juvenaly and Father (later, St.) Herman, and others were assigned to be missionaries in Alaska, and they trekked 8,000 miles across Russia, Siberia, and the Pacific Ocean, arriving at last on Kodiak, Alaska on September 24, 1794. They worked with immense zeal, and within two years, more than 12,000 Alaskans had embraced the Christian Faith.
Father Juvenaly began missionary work on the mainland the next year, baptizing more than 700 Chugach Sugpiag Indians, later many Athabaskan Indians, then moved northwest toward the Bering Sea, but then disappeared. Although nothing is known for certain about the circumstances of his death, local oral traditions among Alaskan peoples tell of the martyrdom of a priest, which appears to have been Father Juvenaly, who apparently frightened some Eskimos who did not understand his gestures in making the sign of the cross, and, by the immediate order of a Yupiat shaman, Father Juvenaly was killed by arrows and spears.
His missionary activity was brief, but zealous and energetic, and showed immense success in a short time in bringing the saving Gospel to the native peoples of Alaska.
Holy St. Juvenaly, pray to God for us.
