"The lust for certainty is troubling to many"?  Speak for yourself.  That statement is utterly nonsensical, since the Church was founded by Jesus Christ Himself (I assume you concur) and He called Himself the way, the TRUTH, and the life.  How can anyone who honestly follows Him think the TRUTH is irrelevant?  What if only four Cardinals sought clarification of some elements of Amoris Laetitiae?  They raised valid questions which need to be settled.  You suggest their concerns should be treated as if they were involved in a popularity contest.  To suggest that their expert concerns be disregarded because they are only four in number ["a tiny number"] is a logically baffling non-sequitur.  It dismisses their concerns without addressing their validity and crucial importance.  MAYBE ok in a political election;  dangerous and inadmissible when what is at state is settling what IS and IS NOT Catholic doctrine.  You call for less study, less thinking, less clarity.  That really scares me.
