The two principal parts of the Holy Sacrifice of the Mass are: (1) the Liturgy of the Word and (2) the Liturgy of the Eucharist.
The Liturgy of the Word includes the Scripture readings together with the homily, the Profession of Faith, and the Prayer of the Faithful.
The Liturgy of the Eucharist has three stages: (1) the Offertory rite; (2) the Eucharistic prayer and; (3) the Communion rite. In the Offertory rite, the gifts of bread and wine are brought to the altar and are offered to the Lord. In the Eucharistic Prayer, the saving mysteries of the Lord’s Passion and Resurrection are recalled by a sacramental action which makes these mysteries present again in the midst of the people. In the Communion rite, the Body and Blood of Christ are received in a sacred meal, to gather in closest unity with Christ those who have received life through Him.
