Joseph Marchand (August 17, 1803 – November 30, 1835) was a French missionary in Vietnam, and a member of the Paris Foreign Missions Society.
Born August 17, 1803, in Passavant, in the Doubs department of France, in 1833 he joined the Lê Văn Khôi revolt by Lê Văn Khôi, son of the late governor of southern Vietnam Lê Văn Duyệt. Khoi and Marchand vowed to overthrow Emperor Minh Mạng and replace him with My Duong, the son of Minh Mạng’s late elder brother Nguyễn Phúc Cảnh, who were both Catholics.
Marchand and Khoi appealed to the Catholics to join in overthrowing Minh Mạng and installing a Catholic emperor. They quickly seized the Citadel of Saigon and the uprising lasted two years.
He was canonized by Pope John Paul II in 1988. His feast day is November 30, and his joint feast day with the Vietnamese Martyrs is November 24.
Bishop-elect of Acanthus, Vicar Apostolic of Western Tongking and Martyr; born 20 February, 1808, at Beynat, Diocese of Tulle, France; beheaded 24 November, 1838. He studied successively at the colleges of Beaulieu and Servieres, and in 1826 entered the seminary of Tulle. Meanwhile the desire to devote his life to the evangelization of distant lands matured, and in 1829 he proceeded to Paris and spent thirteen months at the Seminary of the Foreign Missions.
Too young for the priesthood, he was to have been ordained at Pondicherry, on his way to his missionary post. However, a dispensation from Rome permitted his immediate ordination, which took place at Bayeux (1830). He sailed from Havre, 1 December, 1830, and, after spending some time at Macao, in China, arrived in Tongking in the year 1832. His progress in the language of the country was rapid, but eight months after his installation an edict of persecution was issued (January, 1833). Borie had to remain almost continually concealed and to endure great privations.
In 1834, failing health increased the acuteness of the sufferings of persecution. He regained his strength the following year and was enabled to visit even the least accessible Christian communities of the vast district of which he was in charge. He fell into the hands of the persecutors in 1838. During his captivity he received the news of his nomination to the Vicariate Apostolic of Western Tongking, with Acanthus as titular see. Shortly after this, on the 24th of November, 1838, the death sentence was pronounced on him and two native priests; the execution took place that same day. His remains were brought to France in 1843, and are religiously kept at the Seminary of the Foreign Missions, in Paris.
