On September 11, 2013, Pope Francis hosted Gutiérrez in his residence, where he concelebrated Mass with Gutiérrez and Gerhard Müller, then Prefect of the Congregation for the Doctrine of the Faith. Some saw this meeting as a sign of warming relations between the hierarchy and liberation theologians. The same month, "L'Osservatore Romano" published an article by Archbishop Müller praising Gutiérrez. On January 18, 2014, Pope Francis met with Arturo Paoli, an Italian priest whom the Pope knew from Paoli's long service in Argentina. Paoli is recognized as an exponent of liberation theology before the term arose and the meeting was seen as a sign of "reconciliation" between the Vatican and the liberationists.
