In reply to the original post, there is something that many know (or have been taught) but which gets clouded over. It is also something many non-Catholics (and likely a majority of poorly catechized Catholics) often believe about the Holy Eucharist within the Holy Sacrifice of the Mass. A very thoughtful priest I have had the pleasure to know has spoken on this seminal topic: what is the purpose, the central reason, for a Catholic having to participate in the Mass every LORD’s day and Holy Day of Obligation?
The most commonly heard answer is to partake of Holy Communion/Eucharist so as to receive the Real Presence of Jesus in the sacrament. Although that is the height of the Liturgy of the Eucharist, that is NOT the correct answer–canonically or theologically. Eucharist means “thanksgiving” in the Greek and that is the main purpose of participating in the Mass–to give thanks, as well as praise, to the Almighty for all He has done for us. It is one of the reasons why actually partaking of the Eucharist a Catholic is only obliged to do ONCE A YEAR (and, if that is the case, it must be during Easter)!!! When one thinks on that, one will hopefully see that going to mass is not solely about receiving the Eucharist during the Communion rite–it is foremost about giving thanks to our LORD.
When I hear about how divorced and remarried Catholics (assuming no decree of nullity) feel that they can not or should not attend mass, I feel so bad for them. The Holy Sacrifice of the Mass still has value for them; indeed, one could argue that it is still more needed than ever. As the Sacred Writ reflects Jesus said: Nothing is impossible with God. So, all are welcome and even though have some special impediments that may appear to be permanent in nature, the LORD is still worth thanking and praising in the Mass.
