I am not the slightest bit hesitant to say that I believe with the Church that we humans live in a world characterized by a spiritual war, and thus as baptized Catholics we are called to “put on the armor of God.” In an Augustinian sense we must decide where our allegiance lies: are we citizens of God’s kingdom, who happen temporarily to reside in a civil society, or are we full-fledged citizens of the city of men, making room for God when we are able? Catholic teaching on original sin continues to shed light on man’s position in the world. As a result of the Fall, Satan has acquired “a certain domination over man” in spite of our free will. Widespread ignorance of this teaching is the root cause of the crisis of faith facing The Church today. The Catechism teaches the reality of this spiritual combat:
The whole of man's history has been the story of dour combat with the powers of evil, stretching, so our Lord tells us, from the very dawn of history until the last day. Finding himself in the midst of the battlefield man has to struggle to do what is right, and it is at great cost to himself, and aided by God's grace, that he succeeds in achieving his own inner integrity.
Contraception, like all sin, like the original sin, amounts to a revolt against God and his rights as Creator of all that is. Prideful man wills to become like God, deciding subjectively what is moral and immoral for himself. Keep this in mind when viewing the recent debate over Paul VI's Encyclical in this video, where Fr. Iggy compares Humanae Vitae to an embarrassing uncle who sits in the corner during weddings that everybody ignores….
