Abstract

This paper focuses on the possibility of sin as intellectual evil as operative in the contemporaneous culture in the debate over the essential nature of marriage and the accomplishment of the ends of marriage. It presents an account of theology as a science and the application of this understanding and its canons of operation to the issues presented in two recent documents—the Statement of the Wijngaards Institute for Catholic Research and the Affirmation of the Church’s Teaching on the Gift of Sexuality, each of which addresses the encyclical Humanae vitae on the occasion of its 50th anniversary. The paper concludes with an examination of the essential nature of marriage to guide the fulfillment of its ends now described as intrinsic/essential and intrinsic/contingent.
