He participated in congresses and conferences and founded new houses but was noted for having heard confessions for long hours at a time. He began the construction of the Basilica del Sacro Cuore di Cristo Re in Rome (18.05.1920). Pius X had said of Dehon in 1906: "We are looking for saints. Here is one that is being born". Pius XI granted his order definitive papal approval in 1923.
