"The liturgy is the summit toward which the activity of the Church is directed; it is also the fount from which all her power flows” (Sacrosanctum concilium, 10). “For it is the liturgy through which, especially in the divine sacrifice of the Eucharist, the work of our redemption is accomplished, and it is through the liturgy, especially, that the faithful are enabled to express in their lives and manifest to others the mystery of Christ and the real nature of the Church” (Sacrosanctum concilium, 2).
The word "liturgy" comes from the Greek leitourgia, which means a public service rendered by an individual to the community. It was first used among the ancient churches of the East in reference to the Eucharistic celebration so central to the Christian faith. Over time, the term has come to be used in the West to refer to the public prayers of the Church centered on the Eucharistic celebration (the Mass). Liturgy, simply put, is public worship given to God the Father through Christ, Who is present in and through the priest, with whom all the faithful are joined in a solemn act of worship. All liturgy has as its center the celebration of the Eucharist and is an act of thanksgiving to God by His children, adopted through Baptism. As Pope Emeritus Benedict XVI wrote, liturgy is "a kind of anticipation, a rehearsal, a prelude for the life to come, for eternal life" (The Spirit of the Liturgy).
