The obligation to attend Mass on Sundays and Holy Days, is meant to highlight, set apart, and show the extraordinary importance of the Holy Sacrifice of the Mass as "the source and summit of the Christian life" (CCC 1324). "Creation was fashioned with a view to the sabbath and therefore for the worship and adoration of God. Worship is inscribed in the order of creation. As the rule of St. Benedict says, nothing should take precedence over "the work of God", that is, solemn worship" (CCC 347). God doesn't need us to be at Mass, He wants us to be there, not because of what we can offer Him, but because of what He offers to us, most especially the Body and Blood of His only beloved Son.
We look forward to seeing you and celebrating Mass with you and your family!
