Pope Francis himself has taken steps in the right direction, mandating that the Congregation for Doctrine of the Faith take charge of such accusations and then, after the CDF said it couldn’t do it, transferring responsibility to the four Vatican offices charged with overseeing bishops and other ecclesiastical superiors. In 2016, his apostolic letter “As a Loving Mother” lowered the bar for removing bishops from office, from malice in stewardship to inability or incapacity to do the right thing.
For all that, the Vatican officials in these offices have dragged their feet in establishing procedures for removing a bishop and making these known and available.
Pope Francis is doing the right thing, but Vatican officials are dragging their feet. They do not understand that times have changed and that, if they will not be part of the solution, they are problem.
