St. Andrew Bobola, to his persecutors whom he was Evangelizing: “I am a Catholic priest; I was born in the Catholic faith; in that faith I wish to die. My faith is true; it leads to salvation. Do you rather repent; give place to sorrow for sin, else you will be unable, in your errors, to win salvation. By embracing my faith, you will acknowledge the true God, and will save your souls.” (Litt. decr. Pii Xl "Ex aperto Christi latere": AAS XXX, 1938, p. 359.)
