Theology for the Unwanted is a bold, compassionate, and faithful exploration of what it means to belong to the Catholic Church―especially when you've been made to feel like you don't. Drawing on the depth of Catholic theology, scripture, and lived experience, Daniel C. Tillson speaks directly to those who have felt pushed to the margins: LGBTQ Catholics, divorced and remarried individuals, single adults, and others who wonder if there is still room for them in the pews. His answer is clear and heartfelt: Yes, there is.

Writing with pastoral warmth and theological clarity, Tillson shows how Catholic teaching can―and must―engage with the complexity of modern life while remaining rooted in truth. He brings the reader into conversation with scripture, natural law, and contemporary moral theology, illuminating how the Church has developed over time and how it continues to grow. Without campaigning for doctrinal change, this book opens space for discernment, healing, and authentic spiritual maturity―encouraging each person to live fully into the dignity with which God created them.

From Bishop Felix Gmür, Diocese of Basel

“At a time when the Catholic Church is balancing its rich traditions with the demands of modernity, Daniel Tillson offers an insightful word of encouragement. With great sensitivity, he sheds light on the challenges of living as a queer Christian. This book can accompany anyone who wants to reconcile their faith and their identity and is looking for a home and acceptance in the church.

It is my conviction, that every person who is searching for God - even if they may not yet have the courage to talk about certain parts of their life - is a valuable gift for the Catholic community. It is a moment of joy. No one needs to be afraid of the tension that arises when one begins to seek Jesus Christ in his or her life. Those who strive for holiness sometimes take a great personal risk, and the Church is slowly learning to support this search and accompany people on this lifelong journey.”

Dr. Andrea Grillo, Professor of Sacramental Theology

"Theology for the Unwanted" seeks to think about the difference in behavior and sexual orientation in an open society. Charles Taylor distinguished between "honor society" and "dignity society." The honor society "discriminates" according to difference, also thought of as sin. With the society of dignity, differences are thought of as riches. Here is the challenge toward a recomprehension of homosexuality as a difference to be recognized, integrated and assumed. Daniel Tillson's book contributes to an act of recognition grounded in scripture, discernment, and a finally balanced moral theology.

Dr. Michael Lawler, Professor of Systematic Theology

"This excellent and easily readable book lays out a life plan for both LGBTQ and heterosexual individuals: live authentically as our God has created you. This requires establishing a deep spirituality, a seeking of God's will in the life reality in which God has placed us. I have written extensively on the topics treated in this little book, but I still learned a lot. You will too."
