He has not written an encyclical by himself since he became pope. He essentially cowrote one with Benedict. When his encyclicals come I will pay more attention to his words.
It’s coming, alas. And I doubt that anybody except the UN and the URI will like what it says.
Pope Francis won’t be writing it, since he is not very well spoken in either of his two languages (Italian and Spanish). Argentinians from his region speak a non-standard Spanish that is basically an Italianized conglomerate language, even including its pronunciation.
He’s also not a very educated or cultivated person, meaning he doesn’t give a darn about the intellectual or artistic tradition that is the expression of the Faith everywhere (except in Argentina, apparently).
Just rely on the words of Our Lord and those of 2,000 years of Christian thinkers and saints.
