When popes are fallible and when infallible
The Catholic philosopher, Edward Feser, has, I think, written an excellent blog on the current controversy in the Church regarding Amoris Laetita and the dubia publicly submitted to the Successor of Peter, our Holy Father.
The piece is long, but it is really well worth reading. From my own limited brain capacity this seems to present a very logical and respectful case and explains the background very well. He goes in to the history of errors promoted by popes (giving the examples of three) and how this does not contradict papal infallibility. He gives some very clear analysis but without being disrespectful to our Pope. He makes a case for the dubia being made public, and he suggests what are the possible ways forward (he gives three basic possibilities).
It is a long piece but it is the best I have read and its tone I think is also very good. I commend it to you.
