In short: Born Mark Rey in 1577, Fidelis of Sigmaringen traded a successful legal career for the Capuchin order. His life, marked by extreme asceticism and missionary zeal, culminated in a violent death in 1622. Today, he remains a symbol of unwavering conviction, canonized for his commitment to the Catholic Counter-Reformation.

Born into a prominent family in Sigmaringen, Mark Rey initially pursued a path in philosophy and law at the University of Freiburg. Even as a student, he was noted for his severe self-discipline, wearing a hair-shirt and abstaining from wine. His early professional life as a lawyer in Colmar earned him the reputation of the 'poor man's lawyer' for his ethical approach to advocacy, where he strictly avoided disparaging adversaries. However, disenchanted with the moral compromises of his profession, he joined the Capuchin friars, taking the name Fidelis—meaning 'faithful'—in reference to a promise of a crown of life for those who remain steadfast.

Fidelis became a central figure in the Catholic Counter-Reformation, particularly in the Graubünden region of Switzerland. His missionary work was highly effective, leading to numerous conversions that incensed local Calvinists. By 1622, tensions had escalated significantly. Fidelis, seemingly aware of his impending fate, began signing his correspondence with a grim Latin phrase predicting he would soon become 'food for worms.' His premonitions were matched by his actions; during a mission in Seewis, he refused to flee despite threats to his life, declaring that death was his joy and gain in the service of his faith.

On 24 April 1622, while traveling between Grüsch and Seewis, Fidelis was confronted by twenty Calvinist soldiers. When he refused to renounce his beliefs, he was struck down. According to accounts, he died while praying for his executioners. Following his death, his body was reportedly found incorrupt six months later. His influence persisted beyond his martyrdom; the Protestant minister who had led the attack on him eventually converted to Catholicism, and Fidelis was officially canonized by Pope Benedict XIV in 1746.
