In the Roman Catholic Church (and also in some other Christian traditions like Anglican and Orthodox), the Mass is the central act of worship. It commemorates and makes present the sacrifice of Jesus Christ, especially through the celebration of the Eucharist (Holy Communion). The word Mass comes from the Latin phrase Ite, missa est (“Go, it is the dismissal”), which was said at the end of the service in early Christianity.
