There are 5 main parts to the Catholic mass: 1) Introductory Rites which include entrance hymns, greetings, and opening prayers; 2) Liturgy of the Word involving scripture readings and a homily; 3) Liturgy of the Eucharist where the bread and wine are consecrated and become the body and blood of Christ; 4) Communion Rite during which communion is received; and 5) Concluding Rite with final blessings and dismissal. Each part involves traditional rituals and prayers that make up the overall structure and meaning of the mass.
