WHAT IS LITURGY?
Liturgy- a form or formulary according to which public religious worship, especially Christian worship, is conducted.
The American Heritage Dictionary defines liturgy as: "1) The rite of the Eucharist. 2) The prescribed form for a public religious service; ritual." In Scripture, it says that there is not a "prescribed form for a public religious service set up."
MASS AS SACRIFICE
In the Catholic Church, the Eucharist is a true sacrifice, not just a small meal, as many people say. The first Christians knew that it was a sacrifice and proclaimed this in writing. They noticed the sacrificial meaning of Jesus’ instruction, "Do this in remembrance of me". In other words Jesus said, "Offer this as my memorial offering."
LITURGY AND COMMUNITY
Liturgy and Community are help each other in a way because a community can help form or spread the liturgy out in the world. The liturgy can also, not only bring many people together in unity, but bring them together to Christ.
LITURGICAL DIVERSITY IN THE CHURCH
In different churches all over the world, there is a variety of traditions that are present. For example, in the Church I attend, everyone kneels during the Eucharist Liturgy, but in another church I have visited no one kneels.
The liturgy can be both unified and diverse because every church as a liturgy that brings many people together, but different ways of celebrating in it.
