While I was going thru RCIA I was told that mass readings the same everywhere in the world, with few exceptions for parishes having specific celebrations. But on a few occasions that I’ve checked the iPhone iBreviary app which is endorsed by Rome, the readings were NOT the same.
Are the readings the same or not?
I was also told that if I was to go for mass everyday for 3 years, I’d complete the whole bible. Anybody checked this?
Here is what happens on those days when we see different readings from different sources:
On the one hand, readings at Mass will be according to the lectionary cycle: That means that if it’s Friday of the 14th week of Ordinal time (for example July 3) the readings would be week 14 Friday, and would be “the same everywhere”.
However, July 3 is also the feast of St. Thomas the Apostle, and so the readings might be those specifically for St. Thomas, or for “an Apostle”
July 3 was also First Friday, so any of the 3 sets of readings for First Friday (years A, B, or C) might have been read.
Sometimes these celebrations are obligatory (they must be done) and sometimes they are optional. Sometimes also, there is more than one saint on any particular day.
For weekday Masses (unless they are major feast days) the priest has the option of choosing either the readings proper to that day (St Thomas), or those from the lectionary for the appropriate day of the week (Friday, week 14 to keep the example).
Sometimes there is value in reading the Scripture appropriate to the saint or feast of the day. But there is also a value in keeping the “weekly” readings because these are very often a continuation of yesterday’s readings, and of course, the prelude to tomorrow’s readings (the
Lectio Continuo or continuous readings). It’s up to the priest celebtating that particular Mass to decide which is the more important value under the circumstances, as they are both legitimate.
On days like these, many printed sources will either list the various options, or will simply choose only one of the options to publish. The fact that 2 sources might be “in conflict” doesn’t realy mean anything beyond an expression of the choices made by the publishers.
