This pope is a communist. He supports the globalists agenda.

Papal resignation linked to inquiry into 'Vatican gay officials', says paper
Pope Benedict's resignation linked to gay conclave: report
"A 300-page dossier compiled by three cardinals investigating the theft of Vatican documents was reportedly given to the Pope the day he decided to resign. The investigation is said to have uncovered a number of factions within the Vatican of gay men who have engaged in sexual activity with male prostitutes and at organized sex romps....Male prostitutes who had pictures of the priests dressed in drag and others performing gay sex acts were behind the extortion, The Daily Beast reported."
I find it almost impossible that Benedict was not involved in gay sex, directly, himself. Many of the reports focus on other "gay Vatican priests and officials" but do not implicate Benedict himself. If he was clean, and without sin, all he had to do was punish the guilty and wash the house.
But he didn't do that. He resigned. Quickly.
