Can a couple get married on a holy day of obligation?
What about (more generally) on a Sunday (which, in a certain sense, is a holy day of obligation)?
The Rite of Marriage may be used anytime except during the Triduum.
A marriage that is celebrated on Sunday or a Solemnity, utilizes the prayers and the readings of the day. One of the readings from the wedding liturgy can be substituted, except on Christmas, Epiphany, Ascension, Pentecost, Corpus Christi, or any Holy Day of Obligation. Such weddings would necessarily include the Gloria and the Creed, and, I would argue, a collection! (Just to make it truly Catholic.)
That’s the universal law.
A local parish may have (a wise) rule against weddings on Sundays or Holy Days. Father may, moreover, refuse to permit them for legitimate reasons (e.g., he will already be celebrating two Masses that day, or it would put an undue burden on the organist, servers, custodian, etc.).
If a couple reeeeeeeally wants to be married on Sunday or a Holy Day of Obligation, they are welcome to do so at, I suggest, a regular scheduled parish Mass for that day, in the context of the parish Mass. This would mean no dramatic “look-at-me” entrance, no outrageous floral displays, no special seating for family members or the bridal “court,” and the music must be suited for the feast being celebrated.
I can hear the little shrieks of protest even now. “We’ll do it at 3:00 p.m. on Sunday afternoon, we’ll supply our own priest, we’ll supply our own musicians!” Fine. If the pastor is willing to accommodate this, God bless his little pastoral heart. If not, he is perfectly within his rights to refuse to do so.
As an aside, regardless of all the promises solemnly sworn on stacks of Bibles and cross-my-hearts, situations like this – “We’ll provide everything for the wedding!” – nearly always result in problems… from the visiting priest who accidentally leaves the key in the tabernacle, to the guest organist who spills Mountain Dew on the console, to the headaches from phone messages like “SHE got to have HER wedding on Sunday, why can’t I?”
People have the right to the sacraments. They should not be impeded from receiving the sacraments. However, they must be reasonable about the time and the place for the reception of the sacraments.
