“Simultaneous Fulfillment” of Mass Obligation?

Jeff Ostrowski · November 24, 2017

3830 Calendar CCORDING to current USA law, a Catholic may fulfill the Sunday obligation by attending Mass on Saturday evening, sometimes called an “anticipated” or “vigil” Mass. The readings and propers chosen for Saturday night make no difference. (The same holds true for any Holy Day of Obligation.)

Christmas falls on a Monday in 2017.

Can you “double dip” the fulfillment of your Mass obligation? In other words, does attending Mass on Sunday evening fulfill both the Sunday and Monday obligations? Reading the Code of Canon Law, we might erroneously believe this:

Can 1248 • 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.

For years, this has caused tremendous confusion online. Many authors feel we must attend Mass twice but struggle to provide documentation. Some appeal to “the common and constant opinion of learned persons” argument. But the Congregation for the Clergy has already clarified the matter of simultaneous fulfillment by the faithful:

328 simulatneous-fulfillment-mass-obligation DOUBLE DIPPING

I’m not a canon lawyer, but this document seems to leave no room for “double dipping” (as Andrew Motyka dubbed it several years ago). Therefore, you must attend Mass twice—once for Sunday, once for Christmas—but there are many ways this can lawfully be done. You could go Saturday night and Monday night. Or you could go Sunday evening and Christmas morning. My personal preference is to go Sunday morning and Monday morning.

For the record, rules like these apply to the Extraordinary Form as well. (Similar to how EF Catholics are bound by the current laws on fasting and not, say, the 1950s regulations.)

HIS DUBIUM was answered at the precise moment we would expect. After all, “anticipated fulfillment” of Mass obligation was a new concept, and (to be brutally honest) ruptured the traditional practice of the Church, which had always celebrated vigils on the preceding morning. It should be noted—and cannot be repeated enough—that the choice of formularies makes no difference when it comes to fulfilling one’s obligation to attend Mass. As the above document points out:

On the evening of the Fourth Sunday of Advent, when this falls on December 24, it is possible to have both the evening Mass of the Sunday and the vigil Mass of Christmas. In the same way, when Christmas occurs on a Saturday, the evening Mass might be either that of Christmas or the anticipated Mass for the Feast of the Holy Family.

That is why one can attend a Wedding (“Nuptial Mass”) on Saturday evening and fulfill one’s Sunday obligation, although I believe such a Mass cannot begin too early in the afternoon.


Fun fact : Archbishop Bugnini, in that 1974 document, clearly says nobody can be forced to receive Holy Communion in the hand:

Furthermore, even when an Episcopal Conference petitions the Holy See for the faculty to distribute communion in the hand (see Memoriale Domini, May 29, 1969), this manner of reception can in no way be imposed on the faithful. Rather, the freedom and possibility of receiving communion in the traditional manner must always be granted.

It was recently clarified by the USCCB that kneeling of Communion cannot be denied.

Quick Thoughts

19 January 2021 • Confusion over feasts

For several months, we have discussed the complicated history of the various Christmas feasts: the Baptism of the Lord, the feast of the Holy Family, the Epiphany, and so forth. During a discussion, someone questioned my assertion that in some places Christmas had been part of the Epiphany. As time went on, of course, the Epiphany came to represent only three “manifestations” (Magi, Cana, Baptism), but this is not something rigid. For example, if you look at this “Capital E” from the feast of the Epiphany circa 1350AD, you can see it portrays not three mysteries but four—including PHAGIPHANIA when Our Lord fed the 5,000. In any event, anyone who wants proof the Epiphany used to include Christmas can read this passage from Dom Prosper Guéranger.

6 January 2021 • Anglicans on Plainsong

A book published by Anglicans in 1965 has this to say about Abbat Pothier’s Editio Vaticana, the musical edition reproduced by books such as the LIBER USUALIS (Solesmes Abbey): “No performing edition of the music of the Eucharistic Psalmody can afford to ignore the evidence of the current official edition of the Latin Graduale, which is no mere reproduction of a local or partial tradition, but a CENTO resulting from an extended study and comparison of a host of manuscripts gathered from many places. Thus the musical text of the Graduale possesses a measure of authority which cannot lightly be disregarded.” They are absolutely correct.

2 January 2021 • Temptation

When I see idiotic statements made on the internet, I go nuts. When I see heretics promoted by people who should know better, I get angry. Learning to ignore such items is difficult—very difficult. I try to remember the words of Fr. Valentine Young: “Do what God places in front of you each day.” When I am honest, I don’t believe God wants me to dwell on errors and idiocy; there’s nothing I can do about that. During 2021, I will strive to do a better job following the advice of Fr. Valentine.

Random Quote

At the Council of Trent, the subject was raised whether it was correct to refer to the unconsecrated elements of bread and wine as “immaculata hostia” (spotless victim) and “calix salutaris” (chalice of salvation) in the offertory prayers. Likewise the legitimacy of the making the sign of the cross over the elements after the Eucharistic consecration was discussed.
