Pope Francis' approach to LGBTQ issues marked a major, if mixed, shift in tone for the Catholic Church -- from scorn to tolerance and acceptance.

ROME (AP) — Pope Francis suffered two new acute respiratory crises Monday and was put back on noninvasive mechanical ventilation, in another setback to his battle to fight pneumonia, the Vatican said.
