Birth Control

Sign of Contradiction: Contraception, Family Planning, and Catholicism

The Book

The Presentation

Sign of Contradiction: Contraception, Family Planning and Catholicism, is the most comprehensive Catholic resource on family planning available. Current, yet rooted in tradition, it considers this teaching in light of feminism, Theology of the Body, ecology, abortion, Catholic Social Teaching, overpopulation, ecumenism, and more. Anthony Digmann’s book is of inestimable value for thoroughly conceiving the beauty of God’s vision for marital sexuality and the consequences of thwarting it. Learn more about the book.

The presentation draws upon the highlights of Anthony's book of the same title and presents the Church's teaching on "birth control" in light of what experience and data have demonstrated over the last several decades. It offers a fresh, thorough treatment of this unpopular teaching to invite faithful to reconsider this teaching or learn about it for the first time. This presentation is available on DVD, CD, and mp3 Download.

Sign of Contradiction is another valuable contribution to a wholesome Catholic understanding of family, sexuality and the consequences of contraception. This is an important resource written in the voice of the lay faithful.

-Most Rev. Charles J. Chaput, O.F.M. Cap., D.D., Archbishop of Philadelphia


A thoughtful, respectful invitation to those interested in learning (more) about the Catholic position on contraception and family planning. Seminarians, among many others, will greatly benefit from a book that masterfully marshals the evidence and makes the case for the wisdom of this teaching. It answers the questions that seminarians inevitably will encounter in their priestly ministry. Engaged and married couples seem to be increasingly interested in Natural Family Planning; this book will help them too as well as those who minister to them better understand and embrace the Church’s teaching in this area.

–Most Rev. Thomas Zinkula, J.D., J.C.L., Bishop of Davenport


As a physician, many of the problems I see in clinic would be greatly mitigated by following Church teaching as explained in Sign of Contradiction. I will highly recommend this work to all my patients, because it clearly and thoroughly shares a universal truth that unlocks graces, insight, and authentic happiness.

-Alejandro Curiel, M.D., Family Practice Physician


Sign of Contradiction offers an inviting vision into the background and depth of the Church’s life-teaching on Natural Family Planning which, at same time, also exposes the falsehoods of the contraceptive culture. As a former seminary rector and now parish pastor, I could easily recommend this book to seminarians, our future pastors, as well as any Catholic who desires a comprehensive summary of our Church’s teaching. This book is a great service to our Church!

-Fr. Scott Bullock, J.C.L., Judicial Vicar of the Archdiocese of Dubuque


Most people today haven’t rejected Catholic teaching on contraception, they haven’t even considered it. In Sign of Contradiction, Digmann explains how there is no better time than the present to proclaim to the world Catholic teaching on sexuality. He draws on scientific research on natural family planning and contraception done since Paul VI’s encyclical Humanae Vitae and the testimony of users of both NFP and contraception, and masterfully provides an overview of the theological debate that will be useful to teachers, catechists, and Catholics of all stripes.

-Matthew Shadle, Ph.D., Associate Professor of Theology and Religious Studies at Marymount University


A well-researched, thoughtful examination of the contemporary conversation about the Catholic Church’s teaching on and understanding of family planning and contraception. Digmann writes with an accessible, pastoral voice that will help the reader gain a deeper understanding of the doctrinal meaning and experiential implications of the Church’s teachings in these areas as they touch the lives of the twenty-first century Catholic faithful.

-Fr. Douglas Wathier, S.T.D., Professor of Theology at Loras College
