“Science is the study of the handiwork of God.”

Science

Theology

Philosophy

Hello! I have advanced degrees in chemistry, dogmatic theology, and systematic philosophy because I want to see how it all fits together. I am an educator, speaker, author, and mother committed to the intellectual tradition of the Catholic Church.

Author and Speaker

Stacy Trasancos

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. She and her husband, Jose, 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.” She is, at last, pursuing a second doctorate in philosophy. 

By Stacy Trasancos, PhD and Fr. George Elliott

Behold, It is I

Scripture, Tradition, and Science on the Real Presence

Foreword by Bishop Joseph E. Strickland

Christ is really present in the Holy Eucharist! And therefore, the Holy Eucharist is the greatest gift in this world. But many have lost faith in Christ’s presence at every Mass. This compelling book provides the most convincing proofs for the Real Presence of Christ in the Eucharist from Scripture, Tradition, and scientific investigations of Eucharistic miracles. Accompanied by Church Fathers Ignatius of Antioch, Justin Martyr, Irenaeus of Lyons and Cyril of Jerusalem, Fr. George Elliott leads the reader to an encounter with our Lord like a first century Christian. Dr. Stacy Transacos analyzes the popular Eucharistic miracles reported in Bolsena and Lanciano, Italy, and Buenos Aires, Argentina, with a twenty-first-century chemist’s objectivity. Together, Fr. Elliott and Dr. Trasancos lead you from the burning faith of the saints to the light of the Gospels, to modern science, and right back to the Word. With well researched details and thought provoking questions at the end of each chapter, this book will convict and empower you to evangelize to the world that the Holy Eucharist is not a symbol but truly flesh, bone, hands, and feet. “Behold,” Christ said, “It is I.”

Stacy A. Trasancos, Ph.D.

I earned a doctorate in chemistry from Penn State University and then, after converting to Catholicism, a master’s in dogmatic theology (summa cum laude) from Holy Apostles College and Seminary. I am currently also pursuing a second master’s in systematic philosophy. I have seven children and nine grandchildren (so far). Before I converted, I worked as a senior research chemist for DuPont, but I left my career to stay home with my kids, from there becoming a writer, educator, and speaker. My husband, José, and I live with our family in Hideaway, Texas. With over three decades of scholarly pursuit and parenting experience, I am passionate about leading souls to Christ while keeping it real.
