Fun Facts about Holy Trinity Church, Ulaanbaatar: The First Catholic Church in Mongolia

The Catholic Church has, for centuries, ventured into various parts of the world, establishing its presence even in the remotest corners. One such marvel is the establishment of the Holy Trinity Church in Ulaanbaatar, the capital city of Mongolia. As the first Catholic Church in Mongolia, its foundation and growth symbolize the seeds of faith sown in this vast land. Let us delve into some intriguing facts about this fascinating Church.

1. A Recent Foundation

Fact: The Holy Trinity Church was officially inaugurated on November 30, 2003.

Theological Significance: The Catholic Church’s foundation in Mongolia is relatively recent, emphasizing the timeless nature of the Church’s missionary spirit. Jesus said, “Go, therefore, and make disciples of all nations” (Matthew 28:19). Despite being centuries after the early apostolic missions, the Church’s establishment in Mongolia is a testament to this ongoing call.

2. Apostolic Prefecture of Ulaanbaatar

Fact: The Holy Trinity Church’s establishment coincided with the foundation of the Apostolic Prefecture of Ulaanbaatar in 2002.

Historical Context: An apostolic prefecture is a territorial jurisdiction of the Catholic Church that is not yet a diocese. The establishment of such a prefecture indicates a region where the Catholic Church is still in its infancy.

Theological Significance: The Catechism reminds us, “The missionary mandate accompanies us always” (CCC 863). The foundation of the Apostolic Prefecture of Ulaanbaatar reflects the Church’s attentive care to shepherd the fledgling Catholic community in Mongolia.

3. The Pioneer: Bishop Wenceslao Padilla

Fact: The foundation of the Holy Trinity Church and the Apostolic Prefecture of Ulaanbaatar is largely attributed to Bishop Wenceslao Padilla, a Filipino missionary from the Congregation of the Immaculate Heart of Mary.

Historical Context: Bishop Padilla, along with two other priests, arrived in Mongolia in 1992, marking the re-introduction of Catholicism in Mongolia after decades of religious restrictions.

Theological Significance: Paul’s letters highlight the vital role of apostles and missionaries in the early Church. Bishop Padilla’s mission in Mongolia is reminiscent of St. Paul’s journeys, embodying the words, “How beautiful are the feet of those who bring the good news!” (Romans 10:15).

4. A Beacon of Social Work

Fact: Besides being a place of worship, Holy Trinity Church in Ulaanbaatar actively engages in social services, notably assisting children with special needs and running orphanages.

Theological Significance: Catholic social teachings emphasize the importance of helping the marginalized. Jesus said, “Whatever you did for one of the least of these brothers and sisters of mine, you did for me” (Matthew 25:40). The Church in Mongolia embodies this teaching through its dedicated social outreach.

5. Localized Liturgy

Fact: While the Holy Trinity Church celebrates Mass in Mongolian, it also retains elements of the universal Latin liturgy.

Theological Interpretation: The use of local languages in the liturgy was encouraged by the Second Vatican Council to make the mysteries of faith more accessible (cf. Sacrosanctum Concilium, 36). Yet, the retention of Latin elements connects the Mongolian Catholic community to the universal Church.

6. A Growing Community

Fact: Although the Catholic community in Mongolia remains small compared to other religious groups, it has seen consistent growth since the establishment of Holy Trinity Church.

Theological Significance: Jesus used the parable of the mustard seed to describe the Kingdom of God, stating, “It is the smallest of all seeds, but when it has grown it is the greatest of shrubs and becomes a tree” (Matthew 13:31-32). The growing Catholic community in Mongolia is a living testament to this parable.


The Holy Trinity Church in Ulaanbaatar is more than a building; it’s a beacon of faith in a land where Catholicism is relatively new. Its foundation, growth, and the stories interwoven with its existence highlight the Catholic Church’s universality, echoing the words of St. John Paul II, “The Church breathes with both her lungs!” — emphasizing the Church’s mission to reach every corner of the globe. In the vast landscapes of Mongolia, the Holy Trinity Church stands as a testament to the Church’s age-old mission and the timeless message of Christ’s love.
