Eucharistic miracles documented by Carlo Acutis worldwide.

A structured study guide to explore Carlo Acutis's exhibition on Eucharistic miracles with reflection and discussion questions.

Introduction

As a young teenager, Carlo Acutis researched and catalogued Eucharistic miracles recognized by the Church. His virtual exhibition has been translated into many languages and displayed in parishes worldwide. This study guide helps groups explore the Real Presence of Christ through Carlo's work.

Official exhibition: miracolieucaristici.org

Session 1 — What Is a Eucharistic Miracle?

A Eucharistic miracle is a supernatural event in which the consecrated Host shows signs that point to the Real Presence of Jesus Christ — for example, bleeding, transformation into visible flesh, or preservation over centuries.

Key Terms

  • Eucharist — Body, Blood, Soul, and Divinity of Christ under the appearances of bread and wine.
  • Real Presence — Catholic belief that Jesus is truly present after consecration.
  • Adoration — Prayer before the Blessed Sacrament exposed or reserved in the tabernacle.

Reflection Questions

  1. Why did Carlo believe Eucharistic miracles could strengthen people's faith?
  2. How is faith different from scientific proof?
  3. Have you ever spent time in adoration? What was it like?

Session 2 — Famous Cases in Carlo's Exhibition

Explore three well-known miracles from the exhibition:

  • Lanciano (Italy, 8th century) — Host became visible flesh; wine became blood. Scientific studies found human heart tissue and AB blood type.
  • Buenos Aires (1990s) — Host left on the corporal appeared to bleed; tissue identified as heart muscle.
  • Sokółka (Poland, 2008) — Fragment of Host showed tissue consistent with heart muscle under microscopic analysis.

Group Activity

Assign each miracle to a small group. Summarize the story, location, and Church response. Present one lesson each group learned about trust in the Eucharist.

Session 3 — Carlo's Eucharistic Spirituality

"When we face the sun, we become tan. When we face Jesus in the Eucharist, we become saints."

Carlo called the Eucharist his "highway to Heaven." He went to Mass daily and encouraged others to discover Christ in the tabernacle.

Discussion

  1. How can Eucharistic miracles lead people back to regular Mass and adoration?
  2. What obstacles keep young people from believing in the Real Presence?
  3. How could your parish share Carlo's exhibition locally?

Session 4 — Faith and Science

Several Eucharistic miracles have been studied by physicians and scientists. The Church investigates carefully before recognizing miracles. Faith and reason are not enemies — Carlo used both his logical mind as a programmer and his heart devoted to Christ.

Closing Prayer

Lord Jesus, present in the Most Blessed Sacrament, thank You for the witness of Saint Carlo Acutis. Open our hearts to adore You and to proclaim Your Real Presence with courage and joy. Amen.
