ASK FATHER: “Private Mass”… Mass “without people”

From a reader…

I hope your’e doing well and that you’re able to answer my question.
Is a private mass simply any mass not listed in a parish’s bulletin/website?
On one side, I hear/read that a Missa Sin Populo or “private mass” is a mass
with no people in attendance or in the congregation, save an altar server.
Others say that traditionally, the term “private mass” meant any mass not
publicized or announced in a church bulletin/website. I’m part of a lay
faithful group trying to bring the TLM to our diocese and would like to
invite people to go to the priest’s private masses, but I wasn’t sure if
doing so would then change it from a private to a public mass. Please
forgive my use of such clumsy terms; I know that essentially any mass
offered by a priest is public. I hope my point comes across, nonetheless.


I suppose the writer meant “sine populo” though I could speculate that a Missa Sin Populo would be a Mass for people named Sin, like the late, lamented Filipino Cardinal.

As you say, the terms “private Mass” and “public Mass” are not precise. At every Mass that is offered, the Church is present, and therefore, the Holy Mass is always a public matter. Article 2 of the great motu proprio Summorum Pontificum, notes that a priest may use either Missal (the Extraordinary Form or the Ordinary Form) in offering a Holy Mass “sine populo,” and Article 4 adds that the Christian faithful who freely ask may be admitted to such a Mass. This would make such a celebration, technically speaking, a Mass without people with people. Or a Mass with people without people. Or with people, a Mass without people. You get the point.

When I was in my freewheeling days as a college seminarian, there was a rule in our “Guidelines for Community Living” that stated that “No parties may be held in individual rooms. However, spontaneous gatherings are permitted.” Certain members of the seminary would occasional post notices on the bulletin board to the effect that “A spontaneous gathering will be held in room 210 at 8:00 p.m. this coming Friday.”

We can play with language and find ourselves ending up in some interesting places. It seems to me that the clear intention of the Holy Father with this motu proprio is to make celebrations of the Holy Mass using the 1962 Missal a normal part of the life of the Church. I think it can be a helpful rule of thumb to make the distinction between public Masses being those widely advertised on a parish sign, bulletin, website; and private Masses being those not advertised, even if they are well known.

Otherwise, I suppose one could end up putting something in the bulletin stating, “People are invited to a Mass Without People offered on Tuesday at 7:30 a.m.”

    Thank you for the information on the Private Mass. I have been at the FSSP church in Rome, Chiesa della Santissima Trinità dei Pellegrin, asssiting at the main Mass, when at the same time, two other Private EF Masses were underway on side altars. My question is, if there was only a Private Mass and I did assist at this Mass, would the priest offer me Communion?
    Thank you,


    [In Rome, in general, if you are at a priest’s daily (private) Mass at St. Peter’s or some other Church in Rome, the priest will usually ask at the beginning or at the offertory before he offers the host if there are any people who want Communion. He will then put small hosts on his paten for those people.]

    I suppose the Missa pro populo that a pastor is required to offer on behalf of his people on Sundays and Holy Days should generally be expected to be a public Mass. Otherwise if the faithful requested to be there one could have a Missa pro populo sine populo cum populo.

    one of those rare cases where Wikipedia is helpful. It introduces the term “missa solitaria” for Mass without even a server.
    I get the impression that the Church is not saying “these are various forms of Mass you can celebrate” but rather “here’s how you do it if you have one, none, or more than one. “

    What if it were a Mass for People who need People? I hear tell they’re the luckiest people of all!

    When I was attending summer school at a Catholic university we boarded at the adjoining seminary. We knew that every morning at 7 a.m. one of the resident priests celebrated Mass in a side chapel. We were free to attend if we wished. I always assumed that that was the type of Mass referred to by the S.P. He could have celebrated the EF if he wished because it was a private Mass, celebrated whether he was alone or had a gaggle of students in attendance.
