Pristinely dressed in the black robes and scarlet sash of the princes of the Roman Catholic Church, Wisconsin-born Cardinal Raymond Burke sat in his elaborately upholstered armchair and appeared to issue a warning to Pope Francis.

A staunch conservative and Vatican bureaucrat, Burke had been demoted by the pope a few months earlier, but it did not take the fight out of him. Francis had been backing a more inclusive era, giving space to progressive voices on divorced Catholics as well as gays and lesbians. In front of the camera, Burke said he would "resist" liberal changes — and seemed to caution Francis about the limits of his authority. "One must be very attentive regarding the power of the pope," Burke told the French news crew.
