Inscrutabili Divinae (June 22, 1622)

On June 22, 1622, Pope Gregory XV issued the bull Inscrutabili Divinae, urging renewed, orderly evangelism among peoples newly encountered in the Americas and across the widening world. The decree came in an era when ships, trade, and armies often arrived before pastors, and when the line between conquest and Christian witness could be dangerously blurred. By calling for disciplined oversight, the bull aimed to keep mission work tethered to prayer, sound teaching, and accountable leadership rather than political ambition.

The charge echoed the enduring command of Christ: “Therefore go and make disciples of all nations… teaching them to obey all that I have commanded you” (Matthew 28:19–20). It pressed the Church to proclaim plainly, to catechize carefully, and to remember that those hearing the gospel are not trophies of empire but neighbors made in God’s image.

Congregation for the Propagation of the Faith (Propaganda Fide)

Inscrutabili Divinae founded the Congregation for the Propagation of the Faith in Rome, seeking to coordinate missions beyond Europe with trained laborers, doctrinal clarity, and practical support. One key figure in its early work was Francesco Ingoli, appointed the first secretary, who helped organize reports from distant fields and encouraged strategies that included language study, translations, and local instruction.

This effort also addressed tensions created by European patronage systems that sometimes treated mission territories as extensions of state power. By centralizing oversight, the congregation sought to strengthen pastoral care, improve the sending of missionaries, and promote a more consistent gospel witness—especially in places such as New Spain and Peru, coastal West Africa, India, and East Asia.

Witness, Sacrifice, and Hope

The year 1622 also bore sober reminders of the cost of discipleship. In Japan, persecution intensified; the “Great Martyrdom” at Nagasaki (1622) displayed steadfast faith under threat, as believers chose Christ over safety. Such courage magnifies the truth that the gospel advances not by the sword, but by testimony and endurance.

Inscrutabili Divinae stands as a summons to holy boldness and compassionate integrity: to preach Christ crucified and risen, to guard the flock, and to honor the dignity of those evangelized. “For I am not ashamed of the gospel, because it is the power of God for salvation to everyone who believes” (Romans 1:16).
