Introduction
In the case of Priest Francis Truong Buu Diep (Fr. Francis), who is in the process of being declared Beatified on July 2nd, 2026, this essay—drawing from Church documents and personal reflection—seeks to examine his holy life and offer theological insights on the meaning of beatification.
This study is organized into three main sections: (1) a brief biography of Fr. Francis Truong Buu Diep; (2) an exploration of the Beatitude tradition in the Old Testament and the Eighth Beatitude in the New Testament; and (3) key theological insights drawn from the Beatification of a martyr.
1. Priest Francis Truong Buu Diep - A Brief Biography
On August 15th, 2025, Bishop Peter Le Tan Loi of the Can Tho diocese presented documents for the beatification of Francis Diep, detailing his life, character, career, and the significance of his death.
Fr. Francis was born in 1897 in An Giang, Vietnam. He entered sub-seminary in 1909 at age 12, then advanced to major seminary, studying a total of 15 years before his 1924 ordination. He served at Ho Tru parish (1924–1928), as a seminary professor (1928–1930), and at Tac Say parish (1930–1946).
Fr. Francis was killed while protecting his parishioners on March 12, 1946. At this time, North Vietnam had declared independence, while the South remained politically divided and in conflict. French forces, with British support, retook the main cities and moved into the Mekong Delta. The Viet Minh lacked sufficient weapons and training for effective resistance. New movements like Cao Dai and Hoa Hao Buddhism also challenged authorities.
Fr. Francis was remembered as "a good and devoted priest, diligent in religious duties, serious in preserving family values (including his younger sister, brother-in-law, and their two children), and notably generous. He cared for the poor, children, the sick, and those suffering from war or disaster."(a) His presence mattered to all his parishioners as he represented the poor and marginalized, advocating for justice and humanity.
In March 1946, despite warnings to leave Tac Say due to growing conflict, he stayed with his parishioners. On March 12, he was accused and killed. Days later, his decapitated body was found. He was buried at Khuc Treo parish near Tac Say. His death stemmed from disputes with landowners linked to the warring parties, as above.
After his death, Fr. Francis's example inspired many across Vietnam. Some laypeople reported miracles after visiting his tomb and praying for his intercession. These claims spread quickly and drew attention to his legacy. As Vietnamese Catholics migrated, they shared his story, and devotion to Fr. Francis grew up popularly.
In 1969, Fr. Francis’s remains were reinterred at Tac Say Church, where he served 16 years. On January 21, 1997, Bishop Emmanuel Le Phong Thuan designated Tac Say Parish as the Francis Truong Buu Diep Mission Center, making it a Pilgrimage Center.
The Diocese of Can Tho opened the diocesan inquiry in 2013 and sent the completed dossier to Rome in 2017. In 2019, the Dicastery confirmed its validity. On November 25, 2024, the Holy Father recognized Fr. Francis Truong Buu Diep’s martyrdom.
A Vatican letter dated December 3, 2025, announced that his Beatification will be celebrated on July 2, 2026, at the Tac Say Pilgrimage Center, Ca Mau Province, Vietnam.
2. The Beatitude in the Old Testament and in the Eighth Beatitude of the New Testament
The word "Beatitude" in Latin (beātitūdō) derives from "beātus," meaning blessed, happy, or fortunate. In the New Testament, the Greek term μακάριοι (makarioi) conveys a profound joy that originates from God; it describes people who live in the grace and happiness of God's kingdom. Furthermore, this word highlights the special favor and blessing God's bestowed.
In the Old Testament, Beatitude is expressed as blessing, most clearly seen in the covenants God established with Abraham, Moses, and David. In the Abrahamic Covenant, God promised Abram: "Go from your country and your kindred and your father’s house to the land that I will show you. I will make of you a great nation, and I will bless you, and make your name great, so that you will be a blessing." (Gen 12:1-2)
God continued to bless and transform Israel through His laws and commandments: "Come up to me on the mountain, and wait there; and I will give you the tablets of stone, with the law and the commandment, which I have written for their instruction." (Exod 24:12) By giving these laws and commandments, God blessed His people and kept them aligned with His Will.
In the New Testament, Beatitude is reflected in the Song of Mary—the Magnificat—where she proclaims, "he has looked with favor on the lowliness of his servant. Surely, from now on all generations will call me blessed" (Luke 1:48). Yet, the culmination of Beatitude is found in the Sermon on the Mount, where Jesus "teach[es] us much about those who belong to that Kingdom, and upon whom Christ pronounced its highest forms of blessing."(b). As the "New Moses" and Savior, Jesus declared, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matt 5:17). In this way, He presented Himself as the fulfillment of the Law revealed in the Old Testament.
Jesus Christ taught the Beatitudes in Matthew 5:3–12, culminating in the eighth Beatitude.
"Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven. Blessed are you when people revile you and persecute you and utter all kinds of evil against you falsely on my account. Rejoice and be glad, for your reward is great in heaven, for in the same way they persecuted the prophets who were before you." (v.10-12)
Why must it be persecution? Catholics do not seek persecution, but "the observation is that true godliness is usually attended with persecution."(c) Christ reminded His disciples: "Do not think that I have come to bring peace to the earth; I have not come to bring peace, but a sword" (Matt 10:34). The "sword" here signifies the inevitable conflict and division that can arise from following Christ, often resulting in persecution. Recognizing this paradox is essential to Christian life, for it "teaches us much about those who belong to that Kingdom, and upon whom Christ pronounced its highest forms of blessing."(d) At another time, Jesus told Peter: "Simon, Simon, listen! Satan has demanded to sift all of you like wheat, but I have prayed for you that your own faith may not fail; and you, when once you have turned back, strengthen your brothers" (Lk 22:31–32). The author of Acts also emphasized: "It is through many persecutions that we must enter the kingdom of God" (Acts 14:22).
What distinguishes the eighth beatitude from the others? A.W. Pink explains:
"It pronounces a double blessing upon a double line of conduct [...] means being opposed because of right living. Those who perform their Christian duty condemn those who live to please self, and therefore evoke their hatred. This persecution assumes various forms, from annoying and taunting to oppressing and tormenting."(e)
Jesus Christ, who walked this path according to the Father's will before us, taught Christians to embrace joy even amid danger: "though Christ died to take away the curse from us, yet not to take away the cross from us."(f) Therefore, Christians do not seek any path other than Christ's way. In summary, Christians are called not only to follow Jesus Christ but also to reflect Him. The more suffering they endure for their faith in this world, the greater happiness they possess in the Kingdom of God. The examples of Saints and Blesseds discussed here, particularly the situation of Fr. Francis, illustrate this truth.
3. Key Theological Insights from the Beatification of a Martyr
This section aims to explore the theological significance of the beatification of a martyr, using Fr. Francis as a representative example. Accordingly, the explanations may also reference other Vietnamese martyrs.
First of all, Sanctorum Mater Instruction generalizes the meaning of a beatification that:
§ 1. The cause of beatification and canonization regards a Catholic who in life, in death and after death has enjoyed a reputation of holiness by living all the Christian virtues in an heroic manner; or enjoys a reputation of martyrdom because, having followed Christ more closely, he has sacrificed his life in the act of martyrdom. (Part I, Title II, Art.4)
The Church considers three key phases in evaluating a Catholic for beatification or canonization: "in life," "in death," and "after death." For this reason, the Church meticulously investigates and documents every detail of a blessed or saint through historical writings, eyewitness accounts, and reports of miracles (cf. Sanctorum Mater Instruction, Part V, Title VIII). The requirements for beatification or canonization are that the individual "enjoyed a reputation of holiness" or "enjoys a reputation of martyrdom," alongside fully lived Christian virtues. In the case of Fr. Francis, his pastoral role was a testament to his zealous and fervent care, as he willingly chose to remain with his parishioners even in danger. While historical records may not definitively answer whether he was killed specifically for his parishioners, his willingness to risk his life for their sake powerfully illustrates his commitment as a shepherd.
Next, the reputation of holiness or martyrdom is understood as "the opinion that has spread among the faithful about the purity and integrity of life" or "about the death" (Part I, Title II, Art. 5), making such individuals radiant examples for all Christians. Additionally, another aspect of the reputation required for beatification and canonization is the "reputation of intercessory power," which refers to the graces received through the prayers of the blessed or saint (Part I, Title II, Art. 6 & 7). This dimension highlights the reality of the "communion of the Church," as emphasized in the Catholic Catechism:
"The intercession of the saints. "Being more closely united to Christ, those who dwell in heaven fix the whole Church more firmly in holiness.... They do not cease to intercede with the Father for us, as they proffer the merits which they acquired on earth through the one mediator between God and men, Christ Jesus.... So by their fraternal concern is our weakness greatly helped"." (Part I, Section Two, The Creed, Chapter Three, Article 9, Paragraph 5, Number 956)
After Fr. Francis's death, his parishioners, having buried him, prayed and experienced numerous miracles attributed to their beloved pastor. However, the true significance lies not in the pursuit of miracles, but in the enduring impact of his life and death. People—both Catholic and non-Catholic—recognize his radiant example as a faithful disciple of the Divine Master, inspiring genuine interior conversion in many hearts. Today, the Tac Say Pilgrimage Center continues to welcome pilgrims from various religions within and beyond Vietnam. The gathering of so many people to pray with God through Fr. Francis stands as a powerful sign of peace.
Third, an important question arises regarding Fr. Francis: "Was he truly a martyr?" This question is valid because Fr. Francis was not killed by those who were explicitly anti-Catholic; rather, his death resulted from a local conflict, making him a victim of circumstance. As a result, many people interpret the word "martyr" only in its narrow sense—as someone killed specifically for their faith.
However, according to the Sanctorum Mater Instruction (Part II, Title 3), it is essential to clarify that "martyr" encompasses two meanings: (1) "Heroic Virtues" and (2) "Martyrdom." The document emphasizes:
§ 1. If one intends to prove the heroicity of the virtues of the Servant of God, the Inquiry must be instructed "on the ljfe, the heroic virtues and the reputation of holiness and of intercessory power."
§ 2. If one intends to prove the martyrdom of the Servant of God, the Inquiry must be instructed "on the life, the martyrdom and the reputation of martyrdom and of intercessory power."(g)
Therefore, the circumstances of Fr. Francis's death exemplify the first meaning—heroic virtue—which culminates in martyrdom. Like Saint Mary Goretti (1890–1902) and Maximilian Kolbe (1894–1941), Fr. Francis is also regarded as a "martyr" in the sense of having demonstrated heroic virtues.
Fourth, the Church consistently emphasizes that God is the true center of every Beatification and Canonization celebration.
"The Divine Teacher and Model of Perfection, Christ Jesus, who together with the Father and the Holy Spirit is proclaimed as "alone holy", loved the Church as His bride and delivered Himself up for her so that He might sanctify her and make her glorious in His sight."(h)
The Church, therefore, presents the rites, criteria, and practical guidelines for beatification and canonization as "an expression of the 'wonderful things' the Lord works in the life of his People," and notes that "the Church has paid special attention to the liturgical forms and procedures in which praise to the Most High is expressed and new life is given to the faith and piety of the faithful."(i) This balanced approach encourages Christians to "promote the true and authentic veneration" (j) of a blessed or saint, always directing praise and worship to God alone.
Fifth, it is crucial to understand that the Church does not make someone a saint; rather, the Church simply declares that a person is a saint. This distinction is made explicit in the Canonization formula:
"Ad honorem Sanctae et Individuae Trnitatis... auctoritate Domini Nostri Jesu Christi, beatorum Apostolorum Petri et Pauli ac Nostra... Beatum N. N. Sanctum esse decernimus ac definimus, ac Sanctorum Catalogo adscribimus, statuentes eum in universa Ecclesia inter Sanctos pia devotione recoli debere."
(Temporary Translation: For the honor of the Holy and Undivided Trinity… by the authority of our Lord Jesus Christ, of the blessed Apostles Peter and Paul, and of our own… we declare and define that Blessed N. N. is a Saint, and we enroll him/her in the Catalogue of the Saints, decreeing that in the whole Church he/she is to be devoutly venerated among the Saints.)
Similarly, in the Beatification formula, the Church, exercising her authority, declares the heroicity of virtues or martyrdom of the Servant of God and grants permission for public veneration at the local level through a specific formula:
"...facultatem facimus ut Venerabilis Servus Dei N. N. Beati nomine in posterum appelletur, eiusque festum... in locis ac modis iure statutis quotannis celebrari possit."
(Temporary Translation: …we grant the faculty that the Venerable Servant of God N. N. may henceforth be called Blessed, and that his/her feast… may be celebrated annually in the places and in the manner established by law.)
Even when presented with exemplary lives, the Church remains aware that only God has the authority to make someone holy. Thus, in the case of Fr. Francis, the Church acknowledges his reputation for holiness, demonstrated by his heroic practice of all Christian virtues, offering him as a model for all believers.
Conclusion
This study has three parts: a brief biography of Fr. Francis Truong Buu Diep, an examination of Beatitudes in both Testaments with emphasis on the Eighth Beatitude, and a theological reflection on the meaning of a martyr’s Beatification.
The meaning of Beatification and Canonization does not focus solely on the blessed or saint; the Church also desires that all her members be transformed and grow in holiness in their daily lives. Rather than emphasizing miracles, extraordinary phenomena, or superstition, Christians are called to ongoing personal and communal renewal. As Lumen Gentium declares:
"The Church is a 'communion of saints': this expression refers first to the 'holy things' (sancta), above all the Eucharist, by which 'the unity of believers, who form one body in Christ, is both represented and brought about'" (LG 3).
