The Missionary Pope Who Reached the World
When Mauro Cappellari, O.S.B. Cam., became Pope Gregory XVI, the Catholic Church faced political revolutions in Europe while simultaneously encountering unprecedented opportunities for evangelization across the globe. Having previously directed the Church’s missionary efforts through Propaganda Fide, Gregory made worldwide evangelization the hallmark of his pontificate. He established new missionary jurisdictions, encouraged the formation of indigenous clergy, strengthened seminaries, and supported missionaries from Africa to Oceania. At the same time, his apostolic letter In Supremo Apostolatus forcefully condemned the slave trade and the unjust enslavement of human beings, while Mirari Vos and Singulari Nos defended Catholic doctrine amid the intellectual challenges of the nineteenth century. Gregory XVI’s vision helped transform the Church into an increasingly global communion, laying foundations that would bear abundant fruit throughout the modern missionary era.
