Liturgy is a sacred work of worship and service by the People of God. All the faithful, summoned by the Holy Spirit, are called to full, active and conscious participation at the Mass. By virtue of baptism, members of the parish, called and sustained in their ministry by Christ himself, assume roles in the liturgy. Proclaiming the Word of God, Choral singing and instrumental music, hospitality, altar serving and bringing the Precious Body and Blood of Christ to others are all vital dimensions to the Liturgy of the Eucharist. Every liturgical minister strives to serve so that others might better encounter Christ.
The liturgy moves the faithful, filled with the paschal sacraments, to be one in holiness; it prays that they may hold fast in their lives to what they have grasped by their faith; the renewal in the eucharist of the covenant between the Lord and his people draws the faithful into the compelling love of Christ and sets them on fire. From the liturgy, therefore, particularly the eucharist, grace is poured forth upon us as from a fountain; the liturgy is the source for achieving in the most effective way possible human sanctification and God’s glorification, the end to which all the Church’s other activities are directed (Sacrosanctum Concilium #10). Psalm 100 and the Road to Emmaus in the twenty-fourth chapter of the Gospel according to Luke are helpful scripture versus for discerning a call to liturgical ministry.
