I will not surprise anyone if I say that some Christians have a very poor concept of the holy Mass. For them it is a purely external rite, if not a mere social convention. This is because our poor hearts are capable of treating the greatest gift of God to man as routine. In the Mass, in this Mass that we are now celebrating, the most Holy Trinity intervenes, I repeat, in a very special way. To correspond to such great love, we must give ourselves completely, in body and in soul. We hear God, we talk to him, we see him, we taste him. And when words are not enough, we sing, urging our tongue — Pange, lingua! — to proclaim to all mankind the greatness of the Lord.
To “live" the holy Mass means to pray continually, and to be convinced that, for each one of us, this is a personal meeting with God. We adore him, we praise him, we give thanks to him, we atone for our sins, we are purified, we experience a unity with Christ and with all Christians. (Christ is passing by, nn. 87-88)
