Hello,
we’re writing a paper on this topic for class at Seminary right now, so I’ll have a response soon, hahaha, as soon as we get our essays back…
right now, as far as I know, yes, as according to the much quoted canon 917, one may receive Communion twice a day.
Why not more? Especially because it’s a good thing?
Well part of it has to do with bringing something to every Mass. You bring a sacrifice with you (which is also your disposition to receive grace) to Mass and so if you go once a day, you have something to bring and an openness to receive.
If you want to receive Communion more than once, it is likely that you will not have anything new to bring to Mass, although you may have sinned and so can ‘top up’ on grace. However, this is probably why the Church allows you to receive twice per day. Theoretically, I suppose it is possible that one could receive Holy Eucharist many (3+) times per day, each time bringing a new sacrifice, but I suppose the Church in her wisdom knows this is unlikely and so forbids it to save us from falling into abusing this Sweet Sacrament.
Also, our state of life can determine the reasonableness of doing so, for it is unlikely that one would be able to do their proper duties - work, housewife, etc. - and attend numerous Masses per day.
Lastly, I’ve also heard the analogy given (though analogies are always more dissimilar than they are similar), that the Holy Eucharist is the greatest gift, and to receive Him more than once, is like saying, “Thanks for the gift God, can I have another one?”
I hope this helps…
Pax Christi vobiscum, Nic Carvalho
