"According to the evening prayers in my Saint Andrew Daily Missal (Tridentine), irreverence at mass is a sin against the First Commandment. Therefore, I don't think you are allowed to worship at those masses."
Yes, I understand MY irreverence at Mass would be sinful. My question is: is one allowed to attend a Mass that is irreverent? I ask this because I so often see people talking about the reverence of the Traditional Latin Mass as opposed to the NO. Where do we draw the line? Liturgical dancers in tights?
In my diocese, there are three churches I know of that have reverent masses so they would be okay. However, these masses do not qualify because of the immodest dress of many women who attend there, so they get dropped because of that reason. That leaves me with the Traditional Latin Mass as the only acceptable choice.
In regard to irreverent masses, here is where I would draw the line: if you KNOW based on your Catholic training/spiritual formation, that the masses in a particular church are irreverent or invalid, you certainly hav no business attending them, as would be willingly participating in blasphemy, which is a mortal sin. since we can all read and write, no one can really be excused on account of "ignorance of the law". But, I will go ya one further: let's say your parish has such irreverent masses. Should you support the parish financially? MO! If you do, you are at best a fool, and at worst, complicitous in the blashphemy being purportrated. To dontribute (or still worse to raise funds) for such a parish, makes you as guilty as the apostate priest who is conducting the irreverence. And I will guarantee that the priest is not just and unwitting fool - such irreverence is connived at, and quite well planned!
