...”Any deacons or elders are likely to be people he hand-picked and there is no real oversight.” Sorta like Francis picking Cardinals & Bishops who think like him....
It’s not quite that simple. The Pope has a lot of power but there are institutional checks. It’s not like, “Hi, I’m your new pastor. From now on, we’ll call it ‘Frank’s Church’ - I think that’s a catchy name. Here are the new deacons I chose. Oh, I decided to change several church doctrines. You will find the changes in today’s bulletin.”
