that was no ex cathedra statement. Besides, Francis revisited the issue, and wouldn't have done so if the statement by Paul 2 had precluded it. The statement by Paul2 is not binding on the church. He made a declaration but that is not an infallible statement and you know it, unless you think Francis violated an infallible teaching when he agreed to look into it again. I wasn't aware that you are now in the position of determining what is or is not fallible.
