No. The Vigil Mass on Saturday fulfills the Sunday obligation only. It will be for the 2nd Sunday of Advent, not the Immaculate Conception. You can attend a Vigil tonight for tomorrow or go tomorrow during the day.
You are incorrect. Please see
this thread for more info.
A professional canon lawyer who personally advises the Curia has definitively asserted that the vigil Mass on Saturday evening can fulfill
either obligation (though not both).
If you wish to discuss this matter further, I encourage you to join in the discussion in that thread.
I think the clincher in Jimmy’s argument is canon 14, which he cites here:
jimmyakin.com/2004/07/more_on_friday_.html
So, if an obligation is ambiguous, it can’t oblige under penalty of sin. I think the complexity of the question and the positions of Akin, Fr. Z, and EWTN are sufficient, at the very least, to make the obligation ambiguous. Therefore it can’t bind under penalty of sin. Am I wrong here?
No, your argument is quite solid.
I think canon 14 only applies if Akin can show ambiguity.
Friend, you’re not looking at the whole picture here. Think about what you’re saying: Akin, Father Z, and EWTN all say there is no binding-under-pain-of-sin obligation to substitute another penance if one doesn’t abstain on Fridays.
These people may indeed all be wrong, but none of them is stupid, and - as you’ll see if you read below - they’ve already thought thoroughly about every point you raise. Furthermore, none of them is in favor of laxity:
Akin specifically says (see Transformer’s links just above) that he
wishes Friday penance were still canonically binding, and
Father Z directly expresses his desire that the bishops simply reinstate mandatory Friday abstinence from meat.
Yet these and other sources confidently assert that no binding-under-pain-of-sin obligation to do some sort of penance on each individual Friday exists in the United States.
At worst, their argument is ambiguous. Canon 14 self-evidently applies.
The problem for Akin is that Paul VI’s document he cites suggests that the Vatican already had a notion of what powers it was giving to the Conference. So the Conference doesn’t have the authority to change it beyond that.
Read the links Transformer gave. Akin considers and addresses this argument.
Akin then suggests using the fact that Rome confirming the 1966 document as validation for existence of such an authority. But here Akin is mistaken. It might well be that Rome agreed with the 1966 document because it saw what it permitted in it i.e Rome interpreted it the way contrary to Akin’s.
He addresses that one, too.
The fact that Paul VI’ths documents lacks any such authority further strengthens that. So the law is honestly clear if Akin reads it in context rather than tries to read back his interpretation to it.
Now if as Akin suggests, the local law is not clear. It still will not allow someone to simply ignore the Canon Law that is binding on the entire church. He/She will have to fall back to the Canon Law of the Church. What Akin suggests to do seems even more worse in this sense. Rome HAS spoken through its Canons. So when it doubt, the faithful should fall back to that. Not do their own thing.
Your arguments are at best convoluted and most of the time already addressed by Akin’s analysis in those two links.
Look: please, please,
please - in the privacy of your own mind and heart - ask yourself this question, and I
beg you to be as honest with yourself as you are capable:
Do you
really think it is likely that you are right while Akin, Father Z, and EWTN are wrong, even knowing that Akin and Father Z admit that they’re
biased against the very position they have been forced to take on this subject, and do you really think that their arguments -
all of them - are
so self-evidently invalid that canon 14 doesn’t kick in automatically?
Just out of curiousity, how is this ambiguous?
That the faithful are obliged to do penance and that Friday remains a special day of penance does not logically necessitate the conclusion that the proper authorities have formally legislated a clear and therefore binding-under-pain-of-sin obligation to do some form of penance on every Friday except solemnities.
