ORIGINAL NOTES: Today is Monday in the Octave of Pentecost, or at least it ought to be in in the Novus Ordo as it is in the older, Traditional Roman Calendar.
I dig in to what a liturgical Octave, is adding my own comments.
The we hear from the great St. Augustine (+430) on the feast of Pentecost, preaching on 12 June 412. He has interesting wine imagery and talks about what it means to be a living member of the Body of Christ.
