The Eucharist is the “sign” and “cause” of our communion with God and our unity as the People of God. In the Eucharist, we “unite ourselves with the heavenly liturgy” and with one another. Together transformed, we are then sent forth to fulfill God’s will in our daily lives (Catechism of the Catholic Church [CCC], nos. 1325-26, 1332). In this way, the Eucharistic Liturgy is social in nature. It is the celebration through which God draws us into communion with himself and with others, forming and transforming us to live as the Body of Christ in the world.
Students in second grade celebrate First Eucharist in the spring. Preparation takes place at home, separately from the Wednesday evening faith formation classes. Parents are actively involved in this preparation, attending several catechetical meetings and working at home with their child using family-friendly materials. Generally the family must be registered, practicing members of the parish, and participating in the faith formation program, for at least a year before preparing to celebrate this sacrament.
For adults, because Catholics believe that the celebration of the Eucharist is a sign of the reality of the oneness of faith, life, and worship, members of those churches with whom we are not yet fully united are ordinarily not admitted to Holy Communion.
