I. Who Was Father Truong Buu Diep?

Born 1 January 1897 in Cồn Phước Parish, An Giang. Baptised 2 February 1897. His father Michael Truong Van Dang and mother Lucia Le Thi Thanh.

II. A Model Shepherd

“I live among my sheep, and if I must die, I will die among them. I am not going anywhere.” — Father Diep, refusing to flee in 1946

In March 1930, Father Diep was appointed pastor of Tắc Sậy. During his years as parish priest, he established and supported many neighbouring parishes. His compassion for the poor was legendary — he opened his granary to anyone hungry, Catholic or not. In 1946, despite superiors and French authorities urging him to flee, he refused. On 12 March 1946, he was arrested by Japanese deserters and martyred.

“Father Diep was very gentle, but when he preached, his voice could be powerful. He had great compassion for the poor. He remembered that when poor and hungry people came — whether Catholic or not — Father would call them in and open his granary.”

— James Huynh Van Lap, former altar boy

III. Life & Pastoral Ministry

During his sixteen years at Tắc Sậy, Father Diep demonstrated extraordinary commitment. He defended poor farmers against wealthy landlords, earning the title “father of the poor.” He established numerous neighbouring parishes and was known for his simple lifestyle and deep compassion. A comprehensive historical investigation (2011–2017) confirmed that he was killed by Japanese deserters, in odium fidei.

IV. Witness of Charity

The first memorial Mass was organised in 1979 with only about thirty people. But word spread of favours received through Father Diep’s intercession. Today, tens of thousands come each year. In 1997, the Bishop of Cần Thơ formally established the Francis Xavier Mission Center at Tắc Sậy.

“The number of pilgrims on his death anniversary grew larger and larger, reaching tens of thousands — and not only on the anniversary day itself, but throughout the year.”

V. The Path to Beatification

The formal cause began with a meticulous investigation (2011–2017). On 25 November 2024, Pope Francis declared that Father Diep was killed “out of hatred for the faith”, allowing beatification without a miracle. On 3 December 2025, the Holy See approved the ceremony for 2 July 2026, presided by Cardinal Luis Antonio G. Tagle as Special Envoy of Pope Leo XIV.

VI. Significance

The complex includes a three‑tier sanctuary, the solemn marble tomb of Father Diep, prayer gardens, and a five‑storey building that can accommodate around 600 pilgrims. The tomb’s architecture reflects East Asian style, with a curved roof reminiscent of Vietnamese pagodas.
