Fidelis was born in Sigmaringen Germany in 1578. After working as a lawyer he joined the Order of Friars Minor Capuchins and led an austere life of penance, vigils and prayer. Continuously engaged in preaching the word of God, he was commissioned by the Sacred Congregation for the Propagation of the Faith to preach to the Swiss Protestants in the Grisons. On 24 Apr 1622 he was stabbed to death after preaching at the church in Seewis in Switzerland. – CTS New Daily Roman Missal 2012, p 2648; Christian Prayer 1990, p 1117.
