The principal expression of our worship to God is that of the Mass. From the Introductory Rites, to the Liturgy of the Word, to the Liturgy of the Eucharist and ending with the Concluding Rite are all part of our praise and thanksgiving offering.
Mass was instituted by Christ himself at the Last Supper and by participating we confer the graces needed from God’s mercy to expiate the sins of the past and the graces needed from God’s bounty to obtain His blessings for the future.
But it is not this way among you, but whoever wishes to become great among you shall be your servant; and whoever wishes to be first among you shall be slave of all.

As the living Father sent Me, and I live because of the Father, so he who eats Me, he also will live because of Me.
This is the bread which came down out of heaven; not as the fathers ate and died; he who eats this bread will live forever.
Enter through the narrow gate; for the gate is wide and the road is easy that leads to destruction, and there are many who take it. For the gate is narrow and the road is hard that leads to life, and there are few who find it.
