A Vietnamese layman and member of the Lay Dominicans who was put to death in 1839 for sheltering the Christian faith during one of Vietnam’s fiercest persecutions.

Saint Augustinô Nguyễn Văn Mới (c. 1806-1839) was a Vietnamese Catholic layman martyred during the persecution of Christians under Emperor Minh Mạng. A member of the Lay Dominicans, the Third Order affiliated with the Dominican friars who had long worked as missionaries in Vietnam, he lived his faith within the eastern Tonkin Christian community at a time when converts faced increasing suspicion and legal jeopardy from a court that viewed Catholicism as a foreign and destabilizing influence. Arrested for his adherence to the faith, he refused the demand to trample on a crucifix as proof of renouncing Christianity, a common test imposed on suspected Catholics during this period, and was executed on December 19, 1839. He is honored among the 117 Vietnamese Martyrs, laypeople, priests, and bishops canonized together in 1988, whose deaths across two centuries of persecution remain central to the identity of the Vietnamese Catholic Church.

Who Was Saint Augustinô Nguyễn Văn Mới?

Augustinô Nguyễn Văn Mới was a layman of the eastern Tonkin region of Vietnam, born around 1806 into a Catholic community shaped by generations of missionary work by Dominican friars and diocesan clergy. He belonged to the Lay Dominicans, a Third Order association that allowed committed lay Catholics to share in the spiritual life and discipline of the Dominican order without taking religious vows, a sign of how deeply Catholic practice had rooted itself in ordinary Vietnamese village life by the early nineteenth century. During the reign of Emperor Minh Mạng, whose government issued repeated edicts against Christianity and ordered the arrest of both foreign missionaries and their Vietnamese followers, Augustinô was seized for his known adherence to the Catholic faith. As was common practice for those suspected of Christianity, authorities pressed him to demonstrate his renunciation by trampling on a crucifix, a test that many Vietnamese Christians of this era faced and that became one of the defining images of the persecution. Augustinô refused, choosing to affirm his faith even under the threat of execution, and was put to death on December 19, 1839.

Historical Setting

Augustinô’s martyrdom occurred during one of the harshest periods of anti-Christian persecution under Emperor Minh Mạng, who issued edicts in the 1830s ordering Christians to renounce their faith or face imprisonment and death, and requiring suspected converts to trample on crucifixes as proof of apostasy. This persecution fell not only on foreign missionaries but heavily on ordinary Vietnamese laypeople like Augustinô, whose Catholic communities had developed strong lay structures, including Third Order associations, over more than two centuries of missionary presence in Vietnam.

Why the Church Venerates Saint Augustinô Nguyễn Văn Mới

The Church honors Augustinô as a representative of the ordinary Vietnamese Catholic laity who bore the brunt of nineteenth-century persecution, often in far greater numbers than the foreign missionary priests whose stories are more widely told. His membership in the Lay Dominicans reflects a mature, disciplined form of lay spirituality, and his refusal to trample the crucifix under direct threat of death stands as a clear, deliberate act of faith rather than an incidental or ambiguous circumstance of martyrdom.

Canonization and Feast Day

Augustinô Nguyễn Văn Mới was beatified on May 27, 1900, by Pope Leo XIII, and canonized on June 19, 1988, by Pope John Paul II as one of the 117 Martyrs of Vietnam. Their shared feast day is celebrated on November 24 each year, honoring the full span of missionary priests, bishops, and lay Vietnamese Catholics martyred between the seventeenth and nineteenth centuries.

What Catholics Can Learn Today

Augustinô’s story is a reminder that heroic fidelity to the faith is not reserved for clergy or religious but is fully open to ordinary laypeople living their faith within lay associations and village communities. His willingness to refuse a single physical gesture, trampling a crucifix, when it would have cost him his life to refuse, shows how even small acts can carry immense spiritual weight when they concern the honor owed to Christ.

A Prayer to Saint Augustinô Nguyễn Văn Mới

Saint Augustinô Nguyễn Văn Mới, faithful layman of Vietnam, you would not deny Christ even to save your life. Pray for the lay faithful of the Church today, that we may hold as firmly to our belief in smaller trials as you did in your greatest one. Strengthen Third Order members and lay associations who seek holiness within ordinary life, and intercede for the Church in Vietnam that grew from the witness of martyrs like you. Help us never be ashamed to honor Christ before others, whatever it costs us. Amen.
