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.

Features & Benefits

Stacy Trasancos has a Ph.D. in chemistry from Penn State University and worked as a senior research chemist for DuPont before converting to Catholicism. She left her career to stay home with her highly complex composite systems who call her Mommy. In those years, she earned a M.A. in dogmatic theology while keeping a large family together and published five books on the integration of science and theology. In 2018, Dr. Trasancos became the Executive Director of Bishop Strickland’s St. Philip Institute in Tyler, Texas but, once again, returned home in 2022 to work with her husband, Jose. Together they operate Children of God for Life, an organization that fights to end the use of aborted children in research. Dr. Trasancos teaches online science and theology courses for Seton Hall University and Holy Apostles College and Seminary, is a Fellow of the Word on Fire Institute, and frequently appears on Catholic radio, podcasts, and television. After the publication of her book, Particles of Faith, John Farrell at Forbes wrote, “Trasancos represents a very rare bird, the scientist who did not cease to be a geek even after she got religion.”
