201. “Gratia Supponit Naturam”? A Historical Sketch of the Nature-Grace Interdependance (Part I)

The 1992 Catechism of the Catholic Church begins with a section interestingly entitled “Man’s Capacity for God” and deals with the foundational issue of whether or not men and women are naturally open to God and recipients of His grace. The answer of the Catechism is “yes,” and this affirmative answer is the backdrop of the Roman Catholic way of relating nature and grace. Indeed, one of the axes of the Roman Catholic system is the “nature-grace interdependance.” Briefly put, here is a way to introduce it:
 
“[T]he spheres of nature and grace are in irreversible theological continuity, as ‘nature’ in Roman Catholicism incorporates both creation and sin, in contrast to the Reformed distinction between creation, sin, and redemption. This differing understanding of sin’s impact means grace finds in nature a receptive attitude (enabling Roman Catholicism’s humanistic optimism), as against a biblical doctrine whereby entrenched sin leaves us unaware of our reprobate state. Nature is seen as ‘open’ to grace. Although nature has been touched by sin, it is still programmatically open to be infused, elevated, supplemented by grace. The Roman Catholic “mild” view of the Fall and of sin makes it possible for Rome to hold a view of nature that is tainted by sin but not depraved, obscured but not blinded, wounded but not alienated, morally disordered but not spiritually dead, inclined to evil but still holding on to what is true, good and beautiful. There is always a residual good in nature that grace can and must work with. After Vatican II, more recent interpretations of the nature-grace interdependence go as far as arguing that nature is always graced from within. If traditional Roman Catholicism maintained that grace was added to nature, present-day Rome prefers to talk about grace as being an infrastructure of nature. In spite of the differences between the two versions, the interdependence is nonetheless underlined.”[1]
 
This brief description highlights the fact that Rome has historically built its theological system along the lines provided by the nature-grace interdependence. It is therefore useful to better grasp the historical trajectory of the Roman appropriation and elaboration of that relationship. An old but still significant article by Johannes Beumer (1901-1989), a Jesuit theologian at the Gregorian University of Rome, covers much ground in sketching such a history up to the first half of the 20th century[2] and can be the starting point for some further comments and evaluations.
 
Gratia supponit naturam” (grace supposes nature) is the traditional expression that encapsulates the nature-grace interdependence as it is envisioned by Roman Catholic theology. It conveys the idea that man is capable of receiving grace as a natural desire and disposition. As nature is open to grace, so grace is in continuity with nature. The two are distinct but intertwined.
 
Where does this understanding come from? From the patristic age, there are several interwoven threads, but the contours of the motif are still loose and undefined. Both in the West (e.g. Ireneaus and Athanasius) and in the East (e.g. Gregory of Nazianzus and Basil the Great), there is a talk of grace “perfecting” nature as well as the recognition of the pervasive consequences of sin which have marred that disposition of nature to be elevated by grace. These two elements somehow co-exist. While the Fathers contain some ambiguities in this respect, their main focus is to underline the power of grace to perfect the Christian life, i.e. the life of someone who has already received God’s grace, not natural life per se. Theirs is not an abstract reference to nature as such but to the kind of nature that has already been touched by grace and continues to be impacted by it.
 
In the East, however, the stress is increasingly put on the participation of nature to grace as an inherent capacity that is maintained regardless of sin. In Maximus the Confessor, John of Damascus and the Pseudo-Dyonisius, there is a growing insistence that grace cannot work apart from the assumption that nature is disposed to receive grace, welcome it, and be perfected by it. In their view, there is a harmony between nature and grace. Obviously, in this theological understanding, the impact of sin recedes from the fore and becomes less relevant than in a Church father like Augustine. What is prominent is the continuity between nature and grace and their interdependence.
 
In the Medieval period, it is Albert the Great (1200-1280) who teaches that we are by nature disposed to receive grace and that grace presupposes what is natural in us. His famous sentence is “what is in nature is also in grace” (“sicut est in naturis, sic et in gratia”). In his view, grace does not distance oneself from nature nor does it modify nature; rather, grace perfects nature. Along this line, Bonaventure of Bagnoregio (1221-1274) coins the phrase “grace presupposes nature” (“gratia praesupponit naturam”). At this point, sin has disappeared from the forefront of the discussion and its impact is no longer seen as having involved a radical breach or a tragic disruption.
 
According to Beumer, Thomas Aquinas (1225-1274) is the one who has theologized the relationship more forcefully, giving it its mainstream Roman Catholic outlook in the Second Millennium. Building on what had already been envisaged by the preceding Medieval theologians, Aquinas believes that grace needs nature as its substrate, as its logical presupposition, and as the substance that could receive it. Between nature and grace there is concordance. Grace fits nature and vice versa. Sin, though formally acknowledged, is swallowed in nature and considered a weakness or a sickness of nature which nonetheless maintains its original openness to it and capacity for it.
 
It is in the subsequent development of the Thomist tradition (e.g. Bellarmine and Suarez) that one finds an account of the relationship that stresses the distinction between nature and grace, while maintaining their organic link. In Scholastic Thomism grace is seen as the added gift to nature, which can function even without grace. Grace is super-natural, placed on top of nature, as if it were an added layer. In this scholastic view, nature can exist without grace but grace cannot exist without or apart from nature. One consequence of this Thomist account is that the difference between “natura pura” (pure nature) and “natura lapsa” (fallen nature) is even more blurred than in previous versions of the relationship. Sin is always formally acknowledged, but its effects are considered as not having entailed the breaking of a covenant and therefore having brought about spiritual death. Nature is still intact as it has always been since its beginning. Grace is supernaturally added to a nature that has never lost its openness to it. The addition is aimed at elevating nature to a supernatural end, i.e. a higher and superior status. Only secondarily and incidentally, grace deals with the problem of sin. The latter is a kind of road accident that has not stopped the elevation journey; it has only made it more difficult. Ultimately, there is no tension between nature and grace, but harmony and coordination.
 
Beumer’s historical sketch ends here, but the Roman Catholic development of the “nature-grace interdependence” does not stop there. The 20th century saw a significant theological debate over the exact interpretation of the Thomistic understanding of the relationship.
 
Before entering the contemporary Roman Catholic discussions on nature and grace, some provisional conclusions can be drawn from this bird’s eye view of the issue. In all its variations up to the 20th century, the “nature-grace interdependence” has shown how impactful it is on the Roman Catholic view of the (lack of) gravity of sin. Without a tragic view of sin, Roman Catholic anthropology tends to be optimistic in man’s natural possibility to cooperate with salvation, and salvation itself looks like an addition wrought by grace rather than a regenerating miracle of God who brings about life where death reigns. As the opening section of the 1992 Catechism of the Catholic Church indicates with its reference to “man’s capacity for God”, the whole theological system of Rome is shaped around it and away from the gospel.
