I wonder if Francis is following the old Roman tradition of making haste slowly.  I would not be surprised if he sees his pontificate as being trying to accomplish the most he can in his limited time before death or possibly having to resign for health issues.  The priestly ordination of women is something that will not and should not happen over night.  It will need careful planning and  preparation.   Ordination to the diaconate, give the people time adjust, then slowly bring most of them to see that it can work.  He also needs time to replace or neutralize a majority of the JPII and Benedict era bishops, otherwise they would do all they can to sabotage his work.  I am sure many would love to have a reason for an auto de Fe, as popes can be tried for heresy and deposed, even if they can no longer burn them at the state.
