Document. Article written by Gordon Zahn to the editor of the Catholic Herald in response to an article written re: the proposed revision of schema 13 as it relates to nuclear war. Two original copies of the article. ~ Mr. Zahn states that the total destruction of cities and anyone in them (by use of nuclear weapons) is intolerable. If this is tolerated it will negate and ~ repudiate "the insistent protests of all our recent Popes." Mr. Zahn's second objection is that he finds it "unseemly for any spiritual leader. . . to speak in terms of 'the enemy'. The Christian should know no enemy." ~ Catholic Herald
