We left the vigil mass early today (after the homily) because both kids were just meltdown mania.
We intend to go back tomorrow morning, but I’m wondering; Do we need to go back at the 8AM mass time? Or would we do alright to show up around 8:20, and '“pick up where we left off”, so to speak?
Your question brought a smile to the face of an old priest.
I remember the days when I was young and we were under the
vetus ordo – which meant, of course, we operated with the
manuals.
I remember one manualist who held that one who arrived late to Mass would repair the delict by remaining for the next Mass – this was in the days when there was typically a Mass every hour on the hour – and promptly walking out at the corresponding instant in which one had walked in during the preceding Mass.
In the 21st century, I would counsel you to do your best to attend the entire Mass. If you do end up arriving late because the children are again in meltdown, I am confident a choir of manualists will be looking benignly upon you and nodding smilingly.
In all seriousness…the obligation binds in so far as it is reasonably possible. Our beloved Holy Father, in these very days, said we must not be more papist than the Pope, which has become my new favourite expression of this Pope, who is truly God’s gift to the Church.
In the Catechism of the Catholic Church, we read about the obligation:
2181 The Sunday Eucharist is the foundation and confirmation of all Christian practice. For this reason the faithful are obliged to participate in the Eucharist on days of obligation,
unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor. Those who deliberately fail in this obligation commit a grave sin.
What exactly does the Church mean by the word infant? The Code of Canon Law tells us how the word is to be understood:
*Can. 97 §1. A person who has completed the eighteenth year of age has reached majority; below this age, a person is a minor.
§2.
A minor before the completion of the seventh year is called an infant and is considered not responsible for oneself (non sui compos). With the completion of the seventh year, however, a minor is presumed to have the use of reason.*
