Now that we are in the implementation phase of Amoris Laetitia, we can look back on the entire process of the Synod on the family with greater clarity. It is now clear that Pope Francis does not believe that the pastoral discipline regarding the inadmissibility of the divorced and civilly remarried to the sacraments is correct and wishes to overturn it.Yet while he has gone to great lengths to make his mind clear on the subject, he has gone to equally great lengths not to formally teach it.There are two reasons for that. The first is that the tradition is clear, rooted in teaching of Jesus in the Gospel, and it is not possible for even the Pope to change it. Hence Pope Francis has had recourse to ambiguities, hints, private phone calls, and leaked letters to let the Church know that he thinks what he cannot teach.The second reason is that Pope Francis encountered surprising resistance to the Amoris Laetitia agenda, first outlined by Cardinal Walter Kasper in February 2014. The key moment in that resistance took place a year ago, on the opening day of the second family Synod in 2015.
