Holy Body and Blood of Christ

Feast of Corpus Christi: Overview and Significance

Date and Celebration:
- The Feast of Corpus Christi celebrates the real presence of Jesus Christ in the Eucharist, honoring His Body and Blood. It is observed on the Thursday after Trinity Sunday. In some regions, including the U.S., it is celebrated on the following Sunday. This feast highlights the central role of the Eucharist in Christian worship.

Origins and History:
- The feast originated in the 13th century, inspired by the visions of St. Juliana of Liège, an Augustinian nun. She saw a vision of the Church under a full moon with a dark spot, symbolizing the absence of a dedicated feast for the Eucharist.
- Bishop Robert de Thorete of Liège, persuaded by Juliana, established the feast in his diocese in 1247. The first celebration was held by the Canons of St. Martin in Liège. Pope Urban IV later endorsed the feast with the papal bull "Transiturus" on September 8, 1264, setting the date as the Thursday after Trinity Sunday.

Significance and Doctrine:
- Corpus Christi underscores the doctrine of Transubstantiation, which teaches that during the Eucharist, bread and wine become the actual Body and Blood of Jesus Christ. This belief reflects the deep reverence for the Eucharist as Christ's true presence.
- The feast serves as a way to express gratitude for the Eucharist, which was instituted by Jesus at the Last Supper. Unlike Maundy Thursday, which focuses on Jesus' Passion, Corpus Christi celebrates the joy and significance of the Eucharist.

Liturgy and Traditions:
- The liturgical celebration includes a solemn Mass with processions, hymns, and prayers that honor the Eucharist. St. Thomas Aquinas composed the hymn "Pange Lingua Gloriosi Corporis Mysterium," which is sung during the Corpus Christi procession and on Maundy Thursday, emphasizing the profound mystery and glory of Christ's presence in the Eucharist.

Eucharist as a Sacrament:
- The Eucharist is viewed as a sacrament of life, love, unity, and faith. Jesus' words at the Last Supper, "This is My Body given up for you, this is My Blood shed for you," highlight the sacrificial and loving nature of the Eucharist, central to Christian worship and devotion.
