If one wants to come to terms with Roman Catholic theology, sooner than later one needs to address the “nature-grace interdependence.” Roman Catholicism is pervaded by an attitude that is confident in the capacity of nature and matter to objectify grace (the bread that becomes Christ’s body, the wine that becomes Christ’s blood, the water of baptism that regenerates, and the oil of anointing that conveys grace), in the person’s ability to cooperate and contribute to salvation with his/her own works, in the capacity of the conscience to be the point of reference for truth. In theological terms, according to this view, grace intervenes to “elevate” nature to its supernatural end, relying on it and presupposing its untainted capacity to be elevated.
