I gather that the Holy Father wore a stole of Pope Leo XIII on his visit to England; and that some Clever People see this as a Cunning Sign of the Pope's devotion to that all-important document, for some papists the very heart and centre of their Catholic Faith, Apostolicae curae.
I find it very hard to believe that Dr Ratzinger shares the sort of sniggering adolescent nastiness exemplified in such a hermeneutic. I consider it much more likely that the nice old Bavarian gentleman had heard a rumour somewhere, which has evidently not reached his Subtle Interpreters, that it was Papa Pecci who raised Blessed John Henry to the dignity of Cardinal.
He, too, may be aware of Newman's fond sense that Leo's gesture was that of one Christian who had been out of favour during the previous pontificate towards another such. He may even have heard that Leo XIII, at his first consistory, honoured with the Cardinal's Hat two others who had been on the losing side at Vatican I: Haynald and Fuerstenberg (and later Meignan and Foulon). Indeed, at the Council Cardinal Pecci had himself at times taken a rather independent line.
Most striking was Pope Leo's strong and vigorously expressed admiration for Kenrick, Archbishop of S Louis, who at the Council had been not merely an inopportunist but had positively believed that the doctrine of Papal Infallibility was not part of the depositum fidei.
If I were impertinent enough to thrust upon an expectant world my own decoding of the current Sovereign Pontiff's Leonine gesture, I'd explain it as being an expression of all that.
It must be trying for some people that so many popes are insufficiently rabid in their papalism.
