Thankfully, one pope cannot undo 2,000 years of Ordinary Magisterium...or even 200+ years of Magisterium on social issues. Of course, there are a whole lot of people who don't understand that.
What truly frightens me, though, is how the leftist publishers of Religious Ed texts will blow this completely out of proportion. It will take decades to undo the damage this has done with our own children and grandchildren.
