Benedict was in his mid-80s when he resigned. Give the guy a break. He also never wanted the job because he saw what the demonic forces could do a righteous Pope like JPII who was a vigorous man to begin with. Benedict knew his physical limitations and preferred to live a contemplative life in his later years.
“....Benedict knew his physical limitations and preferred to live a contemplative life in his later years.”
Perhaps you should revisit the parable of the three servants and tell me which one was Benedict.
