"We must trust the Spirit, trust this journey and most of all trust ourselves"
This I believe is the essence of Francis' contribution. Did you notice what the "most of all" refers to?
The "ourselves".  "Ourselves" is not only the supremely educated, the finely "formed", the "directors" who lay conclusions on us that are irrelevant to our questions or are irrespective to our conditions. The "ourselves" is the we who are trying to do the best with what we have and clerics, dogmatists, canon lawyers are only elements of what we have, they are not the be all and end all. 
And...while we are putting the didacts in proper perspective we must shed ourselves of the guilt and "dis-memberment" that dissipated our good faith.
