Gregory I
540 — 604 · Feast day: September 3
A monk-turned-pope who held Rome together as the empire crumbled, Gregory converted his family mansion into a monastery before being dragged from contemplative life to the Chair of Peter in 590. He organized famine relief, negotiated with Lombard commanders, dispatched Augustine to evangelize England, and reshaped the Roman liturgy — signing his letters 'Servant of the servants of God.'
