One of the most remarkable and scientifically examined Eucharistic miracles in Church history continues in Siena, Italy. On the night of August 14, 1730, during the vigil of the Assumption, thieves broke into the Basilica of San Francesco (St. Francis) in Siena. They stole the golden ciborium containing 351 consecrated Hosts. Three days later, on August 17, the Hosts were found inside the alms box (poor box) at the nearby Sanctuary of St. Mary of Provenzano. The thieves had thrown them there carelessly. The Hosts were covered in dust, dirt, and cobwebs, some even stuck together. What should have happened is obvious — the Hosts should have quickly deteriorated, become moldy, or turned to dust. Instead, something extraordinary occurred. Despite being exposed to air, humidity, temperature changes, dust, and rough handling, these Hosts have remained perfectly fresh, soft, and incorrupt for nearly 300 years. They still look and smell exactly like freshly baked altar bread. Over the centuries, multiple scientific investigations were conducted. In 1914 and again in 1922, teams of doctors, chemists, and biologists examined the Hosts. Their findings were astonishing: No trace of mold, bacteria, or decomposition The Hosts showed no signs of aging or corruption They retained their natural color, texture, and even taste Chemical analysis confirmed they consist of pure unleavened wheat bread with no preservatives To this day, more than 220 of these miraculous Hosts are still preserved in the Basilica of San Francesco in Siena and are available for public veneration. ------------- This miracle stands as a powerful, ongoing testimony to the Real Presence of Jesus Christ in the Eucharist — that what appears to be simple bread is truly His living Body. As Jesus said in the Gospel of John: “I am the living bread that came down from heaven. Whoever eats this bread will live forever.” (John 6:51)
