In truth, Francis is neither a political conservative nor a liberal, which are Western categories that arose during the French Revolution. If you asked, he’d probably tell you he comes out of the moderate wing of Argentina’s Peronist movement. (I have yet to meet anyone, however, including any of the Argentines I know, who can clearly define what exactly that means.)
Basically, Francis appears to sees himself as a Latin American pastor who takes Church teaching and tradition for granted, and who tries to bring it to bear on situations of suffering he’s seen with his own eyes.
Attempting to read his agenda, including Laudato Sii, as a boost for any political alignment thus is destined to get him wrong.
