There are many reasons I am not a Roman Catholic, but one certainly is the pervasive, historic, and systemic secrecy. Many examples could be offered. For example, the secrecy of the curia coupled with the condescending clericalism I’ve seen firsthand from priests in spite of what Vatican II says about learning from the laity are just a few.
It stretches credulity to think the Roman Catholic church can properly handle such things given its long and problematic history.
And for the record, I taught in Poland and know many dynamic Christians who are in the Roman Catholic church. I just think the overall system is badly broken, but lacks the proper theology in doctrine, leadership, and praxis to make things right.
