The Mass: the central act of worship
As far back as the Acts of the Apostles and Saint Paul's epistles, one finds descriptions of the Christian community gathering to celebrate the Lord's Supper, the Eucharist. In the catacombs in Rome, the tombs of martyrs were used as altars for the celebration of the earliest forms of the Mass, making the tie between the sacrifice of Christ on the Cross, its representation in the Mass, and the strengthening of the faith of Christians explicit.
The Mass is the Church's way of fulfilling Christ's command at the Last Supper to, "Do this in remembrance of Me." As a celebration of the Last Supper, the Mass is a sacred banquet, in which the faithful at Holy Family and throughout the world participate actively through their presence and their role in the liturgy; and through the reception of Holy Communion, the Body and Blood of Christ.

Keeping the Sabbath together
In the Third Commandment, God tells us to "Remember to keep holy the Sabbath day." For the Jews, the Sabbath was Saturday; Christians, however, transferred the Sabbath to Sunday, the day of Christ's Resurrection from the dead. By participating in the Mass, the central form of worship for Christians, the obligation to keep the Sabbath is honored, fulfilling the Third Commandment
Being a Christian isn't a private matter; Christians are called to be Christians together. While one can and should engage in the private worship of God throughout the week, the primary form of Christian worship is public and communal, which renders weekend Mass most important to each and everyone of the faithful.
