When the word "law" is juxtaposed with the word "religion," an American lawyer today is apt to think immediately of the First Amendment to the United States Constitution with its double protection against any governmental interference in "the free exercise" of religion on the one hand and against any governmental "establishment" of religion on the other. From the standpoint of contemporary American constitutional law, religion has become the personal and private affair of individual citizens or groups of citizens. Indeed, in recent decades our courts, in interpreting the "free exercise" clause, have gone far toward immunizing individual and group activities from governmental control, whether federal or state, whenever they are considered by the persons engaging in them to be of a religious character; and at the same time, under the "establishment" clause the courts have struck down most forms even of indirect governmental support of religion, whether federal or state.
