Does an illicit (or at least what the person in question regards as illicit) Mass fulfil your Sunday obligation? If it's the only one on offer should you go to it? What if there's no Gospel or the Liturgy of the Word is done illicitly?
I was talking with an SSPX person who would stay at home on Sunday rather than go to the local Church because there were certain things which she regarded as liturgical abuses in the Mass. It sounded like a pretty bad Mass (sorry, that might not be the best way to describe a Sacrament whatever the case!) but as long as it actually happened (transubstantiation takes place) should one go to it if it's the only one available?
An "illicit" Mass does not mean an invalid Mass, and doing something "illicit" does not render the whole Mass illicit. As to if things in the Mass were illicitly done, you only have her word for it, and remember, the SSPX are not in full communion with Rome and their priests are illicitly saying Mass, although their Eucharist is valid. So it seems rather ironic for her to make any statements about the Mass at the local church being illicit.
Missing Mass on Sunday is a grave sin, and one's personal perception of Mass does not affect that obligation. The only person who can determine the Mass itself to be illicit is the local Bishop or the Pope, who can then ask people to not attend those Masses. Otherwise, you are obliged to go Mass even if you don't like the Mass that is available. God is what is important here, not oneself.
