Desiderius of Langers, Bishop, Martyr

Today we commemorate Desiderius. According to Butler:

WHEN Queen Brunehaut governed the courts of her two sons, Theodebert, king of Austrasia, and Theodoric of Burgundy, this zealous pastor boldly reproved her for her incests and cruelties; but a sermon which he preached before her and Theodoric on chastity, chiefly in the words of St. Paul, procured him the crown of martyrdom; for, in his return home, he was by their order and contrivance murdered by three assassins in a village now called St. Didier de Chalaraine, near the brook of that name in the principality of Dombes, in 612.
