Yes. If anyone needs the reference:
Can. 1248 §1. A person who assists at a Mass celebrated anywhere in a Catholic rite either on the feast day itself or in the evening of the preceding day satisfies the obligation of participating in the Mass.
Gabriel wrote:I understand the Mass assigned to the Sunday as the texts given for that celebration in the liturgical books. Therefore Pentecost Sunday has two sets of texts assigned: Vigil and Day Masses. Therefore the Vigil Mass fulfills the OBligation.
I would be happy to accept that interpretation if Eucharisticum Mysterium didn't seem to be saying something else, or at least to be ambiguous.
Gabriel wrote:However there is a link between obligation and the texts used - it is not enough to go to Mass at the right time it has to be the right Mass.
There I think we are in complete agreement.
BTW, I have looked in the reponses published in Notitiae to dubia submitted to the Congregation between 1969 and 1998, but no joy there, alas.
