15 Your leadership called forth the prompt and devoted loyalty of your faithful people, and millions of American Catholics signed the pledge of the " Legion of Decency " binding themselves not to attend any motion picture which was offensive to Catholic moral principles or proper standards of living. We are thus able to proclaim joyfully that few problems of these latter times have so closely united Bishops and people as the one resolved by cooperation in this holy crusade. Not only Catholics but also high-minded Protestants, Jews, and many others accepted your lead and joined their efforts with yours in restoring wise standards, both artistic and moral, to the cinema.
