Behold, It is I: Scripture, Tradition, and Science on the Real Presence

(12 reviews) Write a Review

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."

Editorial Reviews

Joseph Heschmeyer (Apologist, Catholic Answers)

“Three things help to distinguish Behold, It Is I from other (good) books on the Eucharist: its sheer scope, looking at the evidence from Scripture, the Church Fathers, and the scientific evidence (particularly in regard to Eucharistic miracles); its measured approach, in terms of what we can (and can’t) prove; and the helpful summaries (and starter questions) at the end of each chapter. A great resource for someone trying to grow in understanding and devotion for the Holy Eucharist.”

Fr. Robert J. Spitzer SJ, PhD (President of Magis Center of Reason and Faith and author of For God So Loved the World )

“Dr. Stacy Trasancos and Fr. George Elliott present an informative, inspiring, and confirmatory volume showing the complementarity of faith and reason in assenting to the real presence of Christ in the Eucharist. Built on the foundation of faith given in the scriptures as well as the testimony of four early Church Fathers, they then consider the scientific investigation of three Eucharistic miracles, one of which occurred in 1996 in Buenos Aires when Pope Francis was archbishop. Though the evidence of the host transformed into part tissue has significant probative value, Trasancos cautions that the evidence is incomplete, meaning that it should be treated as “seeds that affirm our faith more than irrefutable proofs to convince the doubter.” Nevertheless, when these miracles are seen within the context of scripture and church tradition, they constitute what St. John Henry Newman called “an informal inference”—a complementary, mutually corroborative network of evidence that enables us to reasonably assent through faith to the truth that Jesus Christ is really present in the Eucharist. This book will enrich your faith in the source and summit or our religious life.”
