Hi Fr Francis, I recently heard that if we attend midnight mass on Dec 24th, we do not need to attend Christmas Day mass on December 25 to fulfill “Christmas obligation”. This year is different as Christmas day is a Sunday. We need to go to mass on Christmas Day to our Sunday mass “duty”. But if neither Christmas eve nor Christmas Day falls on Sunday, we only need to attend either midnight mass or Christmas Day mass. Is this correct. What about Easter Vigil and Easter Day masses?
