The resignation of the Pope is extraordinary. Likely right, deeply perplexing for my Catholic friends.
It is, however, a rather interesting modern precedent.
Canada’s Queen, (PBUH), is getting on. In fact she is older than the Pope. However, to date, the Queen has shown no sign of abdicating in favour of Charles. It is just possible that the Pope’s retirement might open the way for our Queen to gracefully retire.
I am not saying she should; rather, the Papal precedent might allow her to consider the option.
