The Feast of Corpus Christi: Celebrating the Mystery of Divinity Transforming Humanity
Corpus Christi Procession
Known as the solemnity of The Most Holy Body and Blood of Christ and celebrated on the Sunday following Trinity Sunday, the Feast of Corpus Christi has been officially celebrated in the Roman Catholic Church since the mid-thirteenth century. The feast is the result of a series of visions of St. Juliana of Liege, a Belgian canoness regular (a member of an Augustinian order) and a mystic. The visions occurred over a period of more than 20years before she began to understand their meaning. In the vision, she saw a full moon with a dark spot in it. Eventually she came to believe that the dark spot represented the lack of a solemn feast dedicated specifically and exclusively to the Body and Blood of Christ. Working with her confessor and a group of theologians and Dominicans living and working in Liege, she arranged for the feast to be instituted as a local feast of the diocese of Liege in 1246. She and her confessor, Canon John of Lausanne, composed the first music and prayers for the feast. Later, Pope Urban IV commissioned the composition of an office (a ritual of music and prayers) for the feast by St. Thomas Aquinas. Aquinas’ hymn, Pange Lingua, composed for this feast, expresses the idea of transubstantiation— the doctrine that the substance of the bread and wine offered in the Mass are transformed into the substance of the body and blood of Christ without changing in outer appearance.
The Church’s belief in the Eucharistic transformation of bread and wine into Jesus’ body and blood dates to the earliest days of the Christian community. Christians have always gathered to celebrate The Lord’s Supper. The disciples on the road to Emmaus described recognizing Jesus in the breaking of the bread. Understanding of the implications of this great gift, however, has developed and deepened over the centuries.
Like many of the mysteries of the life, death and resurrection of Jesus, the mystery of the Eucharist defies easy explanation. That’s part of the nature of mystery: part of the wonder and awe we experience in the face of the great love God has poured out into all of creation and each of us through the life of Jesus and the gifts of their Holy Spirit. As St. Augustine explained it in his Confessions, Christ says to us, “You will not change me into you, but you will be changed into me.” In the Eucharist, the divine takes over and transforms the profane — the everyday reality we experience. We see and experience no obvious change, yet when we eat the bread and drink the wine that have been transformed into the Body and Blood of Christ, we are ourselves transformed into his mystical Body and Blood. Our bodies don’t absorb his; rather his transforms ours and we are strengthened and pulled into his mission of transforming our world into God’s Kingdom.
