In commentary relevant to "ecclesial institutions" from the upper echelon of the Catholic hierarchy down to the parish level:
When the Church does not come out of herself to evangelize, she becomes self-referent and then she gets sick. (cf. The hunchback woman of the Gospel). The evils that over the course of time happen in ecclesial institutions have their root in a self-reference and a sort of theological narcissism. In Revelation, Jesus says that he is at the door and knocks. Evidently the text refers to his knocking from outside in order to enter but I think of the times in which Jesus knocks from within so that we will let him come out. The self-referent Church keeps Jesus Christ within herself and does not let him come out.
