Liturgy is a special form of prayer that is intended for a community to gather together for prayer and worship.  There are three Liturgies in the Catholic Church: Liturgy of the Word, Liturgy of the Eucharist, and Liturgy of the Hours.  The Liturgy of the Word and Eucharist happen at Mass.  As Mass is a complex spiritual event and the Church asks us for full and active participation, we need many people to help with Mass.  The following ministries all deal with assisting the liturgies in some way.
