Particles of Faith: A Catholic Guide to Navigating Science

How can Catholics explain what the Church teaches about the relationship between science and faith? Scientist, writer, and scholar Stacy Trasancos gives us ways we can talk about how science and our Catholic faith work together to reveal the truth of Christ through the beauty of his creation.  

As a scientist who was led to Catholicism through her work, Stacy Trasancos has confronted some of the basic questions we all face. In Particles of Faith, she teaches us how to explain the symbiotic beauty between our curiosity expressed through science and our love of Christ and his Church.

Trasancos uses her own story, as well as encyclicals such as Pope Francis’s Lumen Fidei, the deep reflections of theologians such as St. Thomas Aquinas, and the exacting work of Catholic scientists like Rev. Georges Lemaître (who proposed the game-changing Big Bang theory), to show how science and faith are interwoven and meant to guide us on the path to truth. 

By the time you finish reading Particles of Faith, you’ll be able to answer questions about, generate discussion on, and explain why science helps deepen your faith.

"Particles of Faith is the perfect book for our time. Stacy Trasancos explains the most fascinating concepts of science in terms that anyone can understand. She cracks open the treasure chest of wonders we encounter as we examine science through the lens of faith." —Jennifer Fulwiler, Catholic radio host and author of Something Other than God

"Many believers today feel caught between two seemingly contradictory worlds: that of their Christian faith and that of rational science. Stacy Trasancos precisely and methodically presents the harmony she has found. Particles of Faith will no doubt be a gift to the more scientifically minded who mistakenly think they must check their brain at the door of the church." —Rev. Dave Dwyer, Executive Director of Busted Halo Ministries

"Among many people today, it's presumed that faith and science are at odds. We are encouraged to choose between the objective facts of biology or physics and the comforting pieties of religion. But, in Particles of Faith, Stacy Trasancos shows why this is a false choice through her own personal story as a scientist and a Catholic. She navigates many controversial touch-points between faith and religion such as cosmology, evolution, and quantum mechanics to reveal how science is supportive of the Catholic faith. Give this book to an atheist friend or any Catholic curious about whether faith can stand alongside science." —Brandon Vogt, Catholic author, blogger, speaker, and content director of Word on Fire Catholic Ministries
