Remember that grace is not added to nature like a roof or a façade on a monument; it grafts divine life on to nature, penetrates and superelevates the soul in its very essence as well as in its faculties, enabling it to perform divine works proceeding wholly from grace and wholly from our natural powers, but not superelevated by grace… This is not possible without a radical dispossession… Nothing more completely strips humanity and empties it of self, nothing exacts more radical purification and suffering.
Jacques Maritain (1882–1973)
