Mass is the form of worship taken in Catholic services, centering on the remembrance of the sacrifice of Christ on Calvary. Mass is an integral part of life experience as a practicing Catholic within the Catholic Church.
Mass is a central practice within the Catholic faith because it satisfies two central Biblical commands, one from God and the other from Christ. The Catholic Education Resource Center explains that Catholic mass is meant to follow the Old Testament command to honor the Sabbath as well as the New Testament command of Christ to commemorate the Last Supper.
According to the official website of Pope Benedict XVI, there are four basic rites of mass, each equally important to the practice of faith. The Introductory Rite begins with a priestly procession, followed by a communal hymn and the chance for members of the church to confess. The Liturgy of the Word follows, involving a communal reading of the Old Testament. The third part is known as the Eucharist, during which time the entire congregation partakes in the Holy Communion. The final part of mass allows the congregation to reflect upon the Eucharist, followed by a brief reading and prayer from the priest before dismissal.
