I read it that he believes he has lost the 'mental agility' to keep up with the flood of crap the modern anti-theistic world is throwing up. He may be much more seriously ill than he appears.
The Vatican is denying illness this afternoon.
If that is true...this raises even more concerns
We went through a number of magnificent rooms, and we finally reached the Pope. He was sitting in the dark and slept in a large arm chair. He was very ill and weak; he could no longer walk. The ecclesiastics in the inner circle looked insincere and lacking in zeal; I did not like them. I told the Pope of the bishops who are to be appointed soon. I told him also that he must not leave Rome. If he did so, it would be chaos. He thought that the evil was inevitable and he should leave in order to save many things beside himself. He was very much inclined to leave Rome, and he was insistently urged to do so.”
