St. Fidelis was born in 1577 at Sigmaringen, a town in the principality of Hohenzollern. In 1612, he received Holy Orders and soon afterward entered the Capuchin Order at Fribourg, changing his baptismal name, Mark, to Fidelis.At the request of the Congregation of Propaganda the Saint undertook, with eight Fathers of his Order, the mission among the Calvinists in the Canton of the Grisons in Switzerland, although his life was threatened. In spite of opposition he gained many converts. He spent much time at the foot of the altar or before crucifix, preparing himself for the martyrdom of which he had a premonition.
On April 24, 1622, Fidelis made his confession, celebrated Mass, and preached at Gruch. At the end of sermon he seemed in an ecstasy and foretold his death to several persons. From Gruch he went to Sewis where he was fired upon by a Calvinist, though without effect.
On his way back to Gruch, the Saint was attacked by an angry mob. He died praying for his attackers and with Names of Jesus and Mary on his lips.
PRAYER: God, You were leased to adorn St. Fidelis, burning with love for You, with the palm of martyrdom in the propagation of the Faith. By his intercession grant that we may be grounded in love, and experience together with him the power of Christ’s Resurrection. Amen.
