" The nicest people .. are usually very tough on those who would exploit .. the most vulnerable .."

This makes the Pope's exceedingly stern rebuke of the Nigerian priests in question, including references both to mortal sin in not following the Pope and to the danger of scandal arising from this all the more intriguing. And troubling.

I have no problem with a pope who alludes to mortal sin or who calls Catholics to obedience or who wishes to avoid scandal. How could I ?

But, it is hard to ignore that this unprecedented (for Francis) rebuke is directed at priests on an impoverished continent over what even in the internet age counts as "a quarrel in a far away country between people of whom we know nothing."

Would Francis have reacted similarly in say a German diocese?
Might C Kasper's very low opinion of the African church have been important?
Is this the only, or the most serious, scandal facing Catholicism?
How come mortal sin figures here but never in 200+ pages of Amoris L ?
