Just as a note, his English is terrible. My guess is that he doesn’t understand it based on his difficulty reading it and sounding out the syllables. It was awful.
That said, Pope Francis is a Jesuit, and to blur that fact, he assumed the name of another more benign order, the Franciscans, stealing St Francis’ name rather than Ignatius’. Nor do I think that those who elected him and permitted his pathway to election were unaware of what they were doing.
And an environmentalist-movement parody of St. Francis at that.
It is notable that in quoting St. Francis' "Canticle of the Sun" in his encyclical, "Laudato Si'", Pope Francis redacted the Saint's lines concerning mortal sin and death.
