I thought that all the speculation was about why the Pope is leaving office.
“This way, leading positions in the Church may be held by people suffering from deep internal wounds, hardly displaying the spiritual level expected of their office; people who have given themselves away to hypocrisy and are especially prone to blackmailing by the enemies of Christianity.”

This Pope recognizes the problem and he wants it dealt with ASAP. He also recognizes his geriatric condition is another situation that has serious implications.
