The Holy Father appears to have deliberately left the question unresolved:

 - Francis avoided addressing the question directly in his apostolic exhortation, left evidence of his intention in an obscure footnote, and then later told reporters that he didn’t remember that footnote.
 - He endorsed the Argentine bishops’ interpretation in a private letter, and the Schönborn interpretation in an airplane interview. Neither was a formal statement of the teaching magisterium.
 - He declined to answer the Dubia submitted by four Cardinals.
 - The Italian Archbishop Bruno Forte reported that Pope Francis had cautioned against clarity, saying: “If we speak explicitly Communion for the divorced and remarried, you do not know what a terrible mess we will make.”

It is clear the Pope wants a "mess" and is happy to create confusion. Why?
