This feast calls us to focus on two manifestations of the Body of Christ, the Holy Eucharist and the Church. The primary purpose of this feast is to focus our attention on the Eucharist. The opening prayer at Mass calls our attention to Jesus’ suffering and death and our worship of Him, especially in the Eucharist.
At every Mass our attention is called to the Eucharist and the Real Presence of Christ in it. The secondary focus of this feast is upon the Body of Christ as it is present in the Church. The Church is called the Body of Christ because of the intimate communion which Jesus shares with his disciples. He expresses this in the gospels by using the metaphor of a body in which He is the head. This image helps keep in focus both the unity and the diversity of the Church.
The Feast of Corpus Christi is commonly used as an opportunity for public Eucharistic processions, which serves as a sign of common faith and adoration. Our worship of Jesus in His Body and Blood calls us to offer to God our Father a pledge of undivided love and an offering of ourselves to the service of others.
