We should always have an attitude of openness so that we might strive to deepen, by means of catechesis, our understanding of what we have celebrated and so that it might become something Alive in our lives. We should do this so that we might be adequately informed in order to be able to have a full, conscious and active participation in the Eucharistic Celebration. We should have a purity of conscience: only the person who is at peace with God and with his brothers and sisters is able to live the Holy Mass fully. The Eucharist is the Sacrament of those who are reconciled, in that it is the high point of the journey to reconciliation with God and with the Church through the Sacrament of Penance. Jesus himself, after he rose from the dead, appeared to the Apostles and told them: “Those whose sins you forgive, they are forgiven. Those whose sins you retain, they are retained” (Jn 20, 22). Only the priest can absolve a person who is contrite from their sins if they approach him in the Sacrament of Penance. A complete, conscious, pious, active, joyful and communal participation. This means: That we should be punctual so that we arrive in Church in time for the beginning of the Mass. We should participate and listen attentively to the Word of God. Share in the Body of Christ with our brothers and sisters: “Take this all of you…”. 191
