On Sunday, 18 October 2026, the Church celebrated the hundredth World Mission Day. For this centenary, Pope Leo XIV chose the theme “One in Christ, united in mission.”
At 8:30 a.m., the participants in the FIAC International Conference “Catholic Action: Synodality and Mission” left the Domus Mariae and made their way to the Pontifical Urban College of Propaganda Fide. After a quiet time of preparation, the community gathered at 9:30 in the College chapel for the Eucharistic celebration.
The Mass was presided over by Monsignor Salvator Niciteretse, Bishop of Bururi in Burundi and coordinator of FIAC Africa.
After the liturgy, there was time for meeting and conversation. Fr Dinh Anh Nhue Nguyen, Secretary-General of the Pontifical Missionary Union, joined the group, along with Fr Riccardo Scorsone, Vice-Rector of the College, and Fr Joseph Buhagiar, its Spiritual Director. It was a moment of fraternal exchange between those who serve the missions in different ways.
Then the group set out for St Peter’s Square, arriving by 11:15. At noon, together with pilgrims from around the world, they joined Pope Leo XIV for the Angelus.
