Francis is still dabbling in Manichaeism, playing with light and dark. Still dualism, binary thinking.  Life is both light and dark. Are we not energized by the darkness of sleep and fatigued by the drain of light? Not either/or but both/and = life.
Francis again promotes the devil in giving him prominence in his preaching, the baptized "proclaim their renunciation of Satan facing West and their profession of faith in God facing East."
Francis still believes in a personal devil!  Sancta excreta!
