I  have no trouble with there being theological engagement with the magisterium. I believe it is good "for the soul," both individual and collective.  What has amazed me about the traditionalists is that they have not hesitated to confront Francis in ways that JPII and B16 would never have tolerated, and didn't.  This crowd were the cheerleaders of the magisterium when it went after "dissenting " theologians. That's why the article's last reference to a quote from R.C. is so delicious.
