Prudence and the Sunday Obligation
As we’re surviving and digging out of the “snow apocalypse” of 2026, there’s been some confusion about the obligation to go to Mass on Sunday in the midst of a snowstorm. Something to clarify is that your pastor has no power to dispense you from Sunday Mass. Neither can the archbishop. Even if has a really impressive mitre.
Why? Because Sunday Mass isn’t just another part of the formative and pedagogical aspects of Catholic Life: from major things like Holy Days of Obligation; to lesser, meatless Fridays; to minor, genuflecting on your right knee. Sunday Mass is constitutive. It makes the Church the Church (cf. 1Cor 11:26; Heb 10:24-25). It’s not a Catholic thing we do. It’s the thing that makes us Catholic in the first place.
Think of it like breathing. You breathe because you’re alive, and you stay alive because you breathe. Stop breathing, and you’ve got bigger problems than missing your favorite pew.
St. John Paul II wrote: “Given its many meanings and implications for Christian and human life, the observance of the Lord’s Day is at the heart of the Church’s life” (Dies Domini, 47). The heart. Not the appendix. Not even a kidney, which you can technically live without if you’re careful.
The Church determines the practical things of worship: Saturday evening vigils count (thank you, Vatican II), various time slots available, winter coats and questionable Christmas sweaters permitted. But Sunday worship “is based on the will of the Lord and on the apostolic tradition that goes back to Easter morning” (Cardinal Ratzinger, The Spirit of the Liturgy, 67). The Catechism teaches this: “The Sunday Eucharist is the foundation and confirmation of all Christian practice” (CCC 2181).
Prudence: because Sunday Mass constitutes our identity as Christians, our default question should always be “How can I get there?” not “How can I get out of this?” We should be planning to make it to Mass the way teenagers plan to attend concerts their parents think are sketchy
Saturday evening vigil before the real snow hits? Brilliant reasoning. Earlier Sunday morning Mass when roads are less traveled? Strategic thinking. Ride with that neighbor who has four-wheel drive and actually knows how to use it? Excellent planning. Mass at the parish three blocks away where you can actually walk safely on shoveled sidewalks instead of driving ten miles to your preferred parish (obviously St. Stanislaus) on unplowed back roads? Swallow your pride and your parish preference.
The question is always first: “How can I get there?” But this question entails prudential judgement, judging whether getting there is actually safe. Not just inconvenient. Not just annoying. Actually dangerous.
Can you walk safely? If your parish is close and sidewalks are cleared, walking might be safer than driving. But if walking means navigating unshoveled paths where one slip could mean a broken hip, or crossing busy streets with poor visibility, then walking isn’t capacity—it’s foolishness. Grandma Geraldine should not be ice-skating to church under the guise of “fulfilling her obligation.”
Can you drive safely? Here’s where honesty gets uncomfortable. “Safely” doesn’t just mean “I technically won’t die.” It means: Are the roads plowed? Can you see lane markings? If you started sliding, could you control your vehicle? Are you confident enough in snow driving that you won’t be that person going 15 mph in the middle lane causing a 12-car pileup? Because endangering yourself is bad; endangering others because you’re determined to make Mass is worse. If your driving skill level in snow hovers somewhere between “terrified” and “pretty sure this is fine” while your car fishtails like a freshly caught minnow, you lack the capacity.
Note that these are subjective questions; each person can answer them differently.
In extreme and on rare circumstances, bishops have declared Sunday Masses suspended (plague, persecution, natural disasters). Even then, it’s not “dispensation” (assumes you can do something but releases you anyway for good reason) but a declaration recognizes that the obligation cannot bind because fulfillment is physically or morally impossible at a particular time and place, in particular circumstances. You’re not being excused; you’re being recognized as someone for whom the obligation cannot physically bind.
Uncle Uther laid up in the hospital lacks the capacity to attend Mass. The ancient principle ad impossibilia nemo tenetur (cf. Aquinas, Summa Teologia, II, Q. 94, Art. 5) —nobody’s obligated to do the impossible. No text to the Archbishop needed. Same goes for anyone without functioning transportation, anyone with mobility issues, anyone recovering from surgery, anyone who’d be risking life and limb in genuinely dangerous conditions. No dispensation needed. You’re already excused. God is not checking to see if you filed the proper paperwork.
Here’s are the questions for prudential discernment: Can I walk safely? Can I get a ride with someone who can drive safely? Can I drive safely without endangering myself or others? If any answer is yes, that’s your answer. If all answers are genuinely no—not “I don’t really want to put on pants”—then you lack capacity. You’re already excused. Stay home, stay safe, pray, reflect on the scriptures of the Mass, give the day to God, and we’ll see you when the plows arrive and civilization resumes.
