He is a human being. He doesn't have the power to take away your hope, or at least I would try to gently suggest that you not give him that power. 

More to the point,  I read his comments in the context of the Petrine ministry he is exercising: either the absurdity of JP2 and Ratzinger's 1994 documents on the subject are going to become so obvious in the context of the way people actually live their lives that a future Peter or Council will correct them, or it won't. I personally believe that it will and I don't know that Pope Francis in any way foreclosed either possibility. Or even if he could had he wanted to.
