I know nothing about Catholicism? Apparently you are unaware of the  pronouncements in MIRARI VOS, IMMORTALE DEI, QUANTA CURA ( to name just a few} re "religious liberty". Perhaps just as striking, you are apparently even less cognizant of the dogmatic pronouncements in QUANTA CURA and VATICAN I {Pastor Aeternus} directly condemning the notion that dogma can be changed or "reversed", even under the ruse of some "deeper understanding". Bad enough to reject or disregard dogmatic teaching, perhaps even worse to not know what the teaching is.
