Born Mark Roy in 1577 in Sigmaringen, Germany, he was renowned for his deep faith, commitment to the poor, and zealous preaching against heresy.

For families, this feast day offers an opportunity to reflect on the virtues of courage, charity, and steadfastness in faith. Saint Fidelis' life serves as a beacon, encouraging us to live our beliefs with integrity and to serve others selflessly, especially those in need.
The Life and Martyrdom of Saint Fidelis
Saint Fidelis, originally named Mark Roy, was born in 1577 in Sigmaringen, Germany. After studying law and philosophy, he became known as the 'poor man's lawyer' for his dedication to defending the oppressed. In 1612, he joined the Capuchin Order, adopting the name Fidelis, and was ordained a priest. His missionary work took him to Switzerland, where he fervently preached against Calvinism, aiming to bring souls back to the Catholic Church. On April 24, 1622, while preaching in Seewis, he was attacked and killed by Calvinist soldiers, becoming the first martyr of the Congregation for the Propagation of the Faith.
His canonization in 1746 and his status as the patron saint of Sigmaringen and the Hohenzollern region highlight his enduring legacy. The annual celebration of his feast day serves as a reminder of the sacrifices made for the faith and the importance of standing firm in one's beliefs.
I came to refute your errors, not to embrace them; I will never renounce Catholic doctrine, which is the truth of all ages, and I fear not death.
