In their "Declaration on Conscientious Objection and Selective Conscientious Objection" of October 21, 1971, 1 the Catholic bishops of the United States acknowledged that their proposal of accommodation for selective conscientious objectors required translation from moral into appropriately jurisprudential terms before it could be enacted as law. In the bishops' words, a prerequisite to enactment is "a policy which can reconcile the demands of the moral and civic order concerning this issue." Professor Greenawalt's chapter, "Accommodation to Selective Conscientious Objection: How and Why," makes a significant contribution to rephrasing the problem in the required jurisprudential terms.
