Criticism of Pope Francis intensified on Saturday after his intervention in the Order of Malta order, with posters appearing around Rome asking: "Where's your mercy?"

The posters appeared on the same day that Francis named a top Vatican archbishop, Angelo Becciu, to be his special delegate to the ancient aristocratic order.

Francis gave Archibshop Becciu, the second most senior official in the Vatican secretariat of state, "all necessary powers" to help lay the groundwork for a new constitution for the order, lead the spiritual renewal of its professed knights and prepare for the election of a new grand master, expected in three months.
