Receiving Holy Communion is not the only reason to go to Mass. It is not even the primary reason to go to Mass. While I waited to be formally received into the Church as a protestant convert, I attended daily Mass for nearly 9 months
, but was unable to receive Communion.
Remember that until recently (in “Church time”), daily Communion was not permitted - but plenty of devout Catholics went to daily Mass anyway. The purpose of attending Mass is to be present at Christ’s Sacrifice on the Cross made present on the altar, and to offer him, through the priest’s oblation, in propitiation to the Father.
The purpose is to offer God our contrition, petitions, worship, praise, and thanks, together with Christ’s Mystical Body the Church. :bowdown:
From a selfish perspective, a reason to participate is also that one receives grace through all of the actions of the Mass (just not as fully and efficaciusly as one would with Communion). :getholy: One receives grace through the prayers of the priest and the people, one receives grace and truth through listening to the proclamation and explanation of God’s word among His people. :bible1: Etc., etc.
Remember above all that, because of the priest’s sacrificial offering of Christ’s true, real and substantial presence in the Blessed Sacrament, each Mass is an act of **supreme and infinite value ** - even if one does not receive Communion.
