The Mass is the center of our Christian life and the offering of thanks to God for His great love toward us. It is not another sacrifice, it is not a reptition. It is the same sacrifice of Jesus that is present. It is a re-presentation of Calvary, memorial, and application of the merits of Christ.
The Mass has two parts: the Liturgy of The Word (after asking for forgiveness of sins) and the Liturgy of The Eucharist, which is an offering to the Father by Jesus the Son and by us, because we are also sons of God. To take advantage of the great spiritual fruits that God gives us through the Eucharistic Celebration, we should know the Mass, understand the gestures and symbols and participate in the Mass with reverence.
