There is no need of a "fifth column" to destroy the Church. The bishops and cardinals who refuse to do anything substantive to remove and punish those who protect sick men, and those who refuse to see that the system must change from the root up in order to truly fix the problem--those are already harming the Church and causing it to "lose the trust of our people." Those do-nothing bishops and cardinals who protect their own are your fifth column. They claim to be members and yet serve only themselves.
