Most Catholic physicians work with the comfortable assumption that we can practice our profession and our faith, fully assimilated into modern American culture and society. Increasingly, we have come to realize that to be a Catholic Christian is by nature to be countercultural. American culture, ordered by the founding fathers in concepts of liberty and freedom, has been profoundly affected by the introduction and reliance on a contraceptive pill. This has changed the mores and sexual behaviors of society in ways that are antithetical to Catholic values. The consequences of contraception have directly led to an acceptance of a broad number of behaviors and attitudes that society insists must be tolerated. This challenges the commitments of Catholic physicians both personally and professionally.
