Here is an excellent definition of ressourcement by the French poet and Catholic essayist Charles Péguy (1873–1914): it is a movement “from a less perfect tradition to a more perfect tradition, a call from a shallower tradition to a deeper tradition, an overtaking of depth, an investigation into deeper sources, a return to the source in the literal sense.” Cited Nicholas J. Healy, Jr., “Evangelical Ressourcement”, First Things 213 (May 2011), 56.
