Today we will see something that, we can truly say, has never happened before. A sitting Pope meeting his predecessor over lunch. At noon, Pope Francis will take his first papal helicopter flight and make his first visit to Castel Gandolfo where he will meet with emeritus Pope Benedict XVI. What the two will discuss will undoubtedly remain a guess for now (we may hope for some report on the meeting, as well as some remarkable photo opportunities, but that is by no means certain).
In a way, we may see this as the final act of the true “handover”, although the meeting has no canonical weight whatsoever. Befitting Pope Francis, he will first and foremost visit Benedict out of courtesy, friendship and love. That, it would seem after ten days, is a very strong driving force behind his actions.
In a few months, Benedict XVI will return to the Vatican to take up his final residence in the Vatican gardens monastery. Will we see or hear anything about that, except for helicopter sightings and a media release? I personally doubt it it very much.

It’s a ‘unique’ event sure, but one can’t say it never happened as there were at least 4 earlier occasions in history where an emiritus pope was alive during the pontificate of another pope, surely they had lunches in the previous millennia and weren’t all envious enemies. Perhaps easier for a pope to visit his living predecessor nowadays… but it’s all speculative.

The first details have emerged, with a photo expected imminently. Pope emeritus now wears just the simple white cassock, without mantella (cape) or fascia (sash). They met as brothers. God bless them both.
