“The Pope who resigned in 2013 for reasons of age Pope also confirms rumours of a homosexual old boy network in the Vatican. Such had been there during his pontificate, and he had smashed it.”
So that is why he left; reasons of age my aunt fanny! He was probably pushed out by this network. JMHO
IOW, he caved.
Not sure why he left, but I do believe he thought they needed a younger, stronger pope....which didn’t happen.
