On April 4, 1941, Rev. Dominic Maria Trần Đình Thủ, an instructor at the Quần Phương seminary, was given permission to establish the Congregation of the Mother Co-Redemptrix in Liên Thủy hamlet, Xuân Ngọc commune, Xuân Trường district, Nam Định province, Vietnam, in the Diocese of Bùi Chu. The congregation was officially established on February 2, 1953, with Fr. Dominic Maria as the superior. In August 1954, during the Partition of Vietnam, the congregation moved to various locations in South Vietnam, eventually settling in Thủ Đức. After the Fall of Saigon, Fr. Dominic Maria was imprisoned by the Communist authorities from June 12, 1975, to April 29, 1977, on accusations of spying for the CIA. Fifty-two companions were also imprisoned for shorter terms. Fr. Dominic Maria was again arrested from May 16, 1987, on charges of state subversion. His sentence was reduced from life imprisonment to 20 years' imprisonment, but he was released early for unclear reasons on May 18, 1993. The congregation's assets were seized, except for a small dormitory for seminarians in Thủ Đức. , the congregation has 700 members worldwide, including 360 priests, 170 brothers, and 10 novices in Vietnam., the U.S. province includes 23 priests, 54 brothers, five novices, seven postulants, and 25 high school students. CRM priests serve parishes in eight states., the congregation has 500 seminarians in Ho Chi Minh City and sponsors 150 in the United States. On April 7, 2017, the congregation was renamed to the Congregation of the Mother of the Redeemer upon the recommendation of the Congregation for the Evangelization of Peoples, due to the "theological ambiguity" of the title Co-Redemptrix.
United States Assumption Province
On April 30, 1975, 185 clergy – about half of the Congregation – left Vietnam as boat people just before the Fall of Saigon. They arrived in the United States at Fort Chaffee and other Operation New Arrivalsrefugee camps. Cardinal Bernard Francis Law, then Bishop of Springfield–Cape Girardeau, sponsored the priests and brothers, inviting them to purchase a vacant Oblates of Mary Immaculate seminary, Our Lady of the Ozarks College, for a nominal price of $1, to use as their U.S. monastery. Between June 30 and September 3, 1975, nine priests, 154 brothers, and four novices arrived in Carthage, a predominantly Protestant town. The Overseas Congregation of the Mother Coredemptrix received formal recognition from the Congregation for the Evangelization of Peoples on September 16, 1975, and the congregation's Assumption Province was established on October 25, 1980, with Rev. Barnabus Maria Nguyễn Đức Kiên as the provincial. The Holy See gave the province a mission to minister to the Vietnamese American community. In 1978, the Congregation organized the inaugural Marian Days at the Carthage shrine. Around 1,500 Vietnamese Catholics from the surrounding area participated. In 1984, a statue of Our Lady of Fatima, also known as the International Pilgrim Statue, was enshrined in the Immaculate Heart of Mary Shrine at the Carthage monastery. The statue is removed once a year during the Marian Days celebration for a procession around Carthage. Archbishop Pierre Martin Ngô Đình Thục died at the monastery in 1984.
