What are holy days of obligation?

• A. Days when the church is closed
• B. Feast days when Catholics are obligated to participate in the Eucharist
• C. Weekdays of fasting
• D. Feast days in the liturgical year on which, in addition to Sundays, Catholics are obligated to participate in the Eucharist

Answer: (D)

Holy days of obligation are special feast days when Catholics are required to attend Mass and participate in the Eucharist. On these days, just like on Sundays, attending Mass is an obligation, adding to the regular Sunday duty. They aren’t about church closures or fasting; they mark specific days in the liturgical year when the Eucharist is celebrated as a central part of worship. Examples often include Christmas and other major feast days, though the exact list can vary by country. The idea matches the statement that these are feast days in the liturgical year on which, in addition to Sundays, Catholics are obligated to participate in the Eucharist.
