The first Apostolic Vicariate of Vĩnh Long was established in 1938 with Ngô Đình Thục appointed as its initial vicar apostolic. A prominent figure within the Catholic Church in Vietnam, he eventually ascended to the rank of Archbishop of Huế. His life was defined by the intersection of ecclesiastical authority and the political maneuvering of the Ngô family during a period of significant regional instability.

Throughout his career, he held various significant titles, serving as a titular bishop and vicar apostolic from 1938 to 1960.

Beyond his religious duties, Thục played a role in the international relations of the Republic of Vietnam. In 1950, he accompanied his brother, Ngô Đình Diệm, on travels to Japan and the United States to secure foreign support. He worked to establish connections with figures such as Cardinal Francis Spellman and engaged with American government officials, including Acting Secretary of State James Webb. These efforts were intended to bolster the Ngô family's political standing and ensure foreign aid for their administration.
Exile and Theological Shift
Following the 1963 coup in South Vietnam, which resulted in the deaths of his brothers Ngô Đình Diệm and Ngô Đình Nhu, Thục remained abroad. He spent his later years in Italy, France, and the United States. During this period of exile, his theological perspective shifted toward sedevacantism. He engaged in independent consecrations of bishops without Vatican approval, leading to his excommunication from the Catholic Church. Before his death in Carthage in 1984, he reconciled with the church.
