The saddest part for me is when he leaves his common law wife, described with the words avulsa a latere meo (torn from my side), which I think is a deliberately violent version of Gen 2:21-24. https://twitter.com/BrVinMary/status/1299422004597207040

And the correct description of the woman in question is common law wife, not concubine.

And Monica and her ambition for her son is probably a large part of the reason why she has to go. Don’t get me wrong. I have a great devotion to St Monica, but in Augustine’s own telling of it, this is something she is (subtly) being criticised for.

Peter Leithart comments on how Augustine has a gift for miniaturising sin, which he does both with himself with the pears, and his mother with the wine-stealing, but in neither is meant to downplay the lust of the flesh, the lust of the eyes, or the ambition of life in both.
