Catechism Paragraph 1069
Part 2:
THE CELEBRATION OF THE CHRISTIAN MYSTERY
The word "liturgy" originally meant a "public work" or a "service in the name of/on behalf of the people."
In Christian tradition it means the participation of the People of God in "the work of God."[5]
Through the liturgy Christ, our redeemer and high priest, continues the work of our redemption in, with, and through his Church.
