In 1548, Bishop Franz promised to suppress the Reformation in Osnabrück and to execute the Augsburg Interim, but fulfilled his promise very indifferently; on his deathbed he received Lutheran communions.
Aastal 1548 lubas piiskop Franz maha suruda reformatsiooni Osnabrückis ja täide viia Augsburgi interim, kuid täitis oma lubadust väga ükskõikselt; oma surivoodil sai ta luterliku armulaua.
