OK, so I know a Sat vigil mass satisfies the Sunday obligation. Does a mass on the evening prior to a holy day likewise satisfy that obligation? In particular, would attending a mass on Christmas Eve satisfy the requirement to attend mass on Christmas Day?
BTW, I realize that attending only one mass when Sundays and holy days are consecutive to one another would not satisfy both obligations. For example, one cannot attend a Sat eve vigil mass to satisfy both (a) a Saturday holy day of obligation, and (b) the Sunday obligation. I’m asking strictly about whether a vigil mass the night before a holy day can be used to satisfy just the requirement to attend mass on the holy day of obligation.
Thanks in advance.
