I had more or less assumed that I wasn't going to find a quotation for today.
Then this came up;
"in necessary things unity; in uncertain things freedom; in everything charity"
once again attributed to St Augustine of Hippo, and once again, (thanks, wikipedia), re-attributed to someone else, in this case
the Archbishop of Split (Spalato), Marco Antonio de Dominus in his anti-Papal "De Repubblica Ecclesiastica"
by which you will see that the phrase originates in a theological context. Here's the wikipedia link:
Well, it might originate from a Christian theological source, but the words have a lot going for them in any context...
starting with which things are to be considered necessary... and that is where everything begins to tumble
No, much better to start at the end and work backwards... "in everything, charity (caritas)"
