World Mission Day, marked for the 100th time on 18 October 2026, was instituted by Pius XI in 1926.
Verifiable fact The message says the same
Leo XIV’s message is headed for the 100th World Mission Day, 18 October 2026, and says that “following a proposal from the Society of the Propagation of the Faith, Pius XI established World Mission Day in 1926.” It is signed “From the Vatican, 25 January 2026 … Feast of the Conversion of Saint Paul”, as InfoVaticana reports. Its points on unity not being “uniformity”, on 1 Corinthians 1:10-12, on the Pontifical Mission Societies the Pope came to know in Peru, and on the 110th anniversary of Blessed Paolo Manna’s Pontifical Missionary Union (founded 1916) are also in the text.

TradWatch analysis A faithful summary
The report stays close to the message and adds no commentary of its own beyond the Spanish centenary slogans, which come from the national DOMUND campaign.
