By now you know that our second Evangelical Calvinism book was just released, the full title being: Evangelical Calvinism: Volume 2: Dogmatics&Devotion. But as you also know Myk and I had a volume 1 Evangelical Calvinism book published under the title: Evangelical Calvinism: Essays Resourcing the Continuing Reformation of the Church (which this subtitle is also attached to our second volume as well). This post will be referencing one of the chapters found in EC1; a chapter written by Gannon Murphy on knowledge of God in John Calvin’s thought.
What I want to focus on, in regard to Gannon’s chapter is his brief but profound development of how the Latin terms religio and pietas function in Calvin’s theological offering when it comes to knowledge of God. As Murphy points out Calvin’s conception of knowledge of God was never a disembodied one; in fact it was more existential. It was never really a philosophical or abstract engagement with some sort of abstract brute conception of a substance that we could correlate through abstract reasoning to the God disclosed in Holy Scripture and Jesus Christ. No, as Murphy argues, for Calvin, knowledge of God was something more akin to knowledge in God; more particularly in Christ. Gannon up-points how the concepts of religio and pietas functioned in this type of dialogical/existential mode for the Christian knower coram Deo (‘before God’). Gannon writes (at length):
Religio and Pietas
The very beginning of the Institutes commences in a statement concerning that which constitutes true wisdom, to wit, that wisdom “consists almost entirely of two parts: the knowledge of God and of ourselves.” Some theologians have argued that this first statement is actually the entire point of the Institutes, a contestable, but not entirely meritless, claim.
It is perhaps customary in our technological age to think of knowledge as a purely apprehensive or propositional enterprise—we have knowledge of this object, or that thing, or such-and-such a set of data. The key to preserving Calvin’s doctrine of knowledge (cognitione), however, is to see it as something much fuller and more “holistic.” In sum, to truly know God is to love him. Theological knowledge is not merely propositional in nature or a matter of mere intellectual assent (assensus). Rather, it must also be experiential, stemming from love that also manifests itself in adoration, trust, fear, and obedience to God. Edward Dowey, for example, refers to Calvin’s concept of knowledge, as “existential knowledge.” The idea of coming to God merely in mind is an utterly foreign concept throughout the Calvinian corpus. Further, Calvin (like Luther) alludes to the nonsensical nature of conceiving of God as a mere object of knowledge.
Calvin uses the terms religio and pietas which, unfortunately, do not translate well into our English words, religion and piety, both of which tend to connote merely a system of ecclesiology or perfunctory, external religious observance. Both words in the Latin, however, denote something much deeper. Re-ligio derives from re, “again” and ligere, “to literally means “careful,” the opposite of negligens. Religio, then, means something more along the lines of “careful attention to” and to be “rebound.” Pietas, while often suggesting merely “dutifulness,” is better understood as “dutiful kindness,” stemming from the Latin root pius (literally, “kind”). Thus, pietas is friendly obedience toward the things of God. It is the perfect opposite of animosity toward godly things—to find oneself welcoming of, and delighting in, his or her Creator.
Calvin, characteristically never wanting to be misunderstood but always desiring clarity for his readers, defines religio as, “confidence in God coupled with serious fear—fear, which both includes in it willing reverence, and brings along with it such legitimate worship as is prescribed by the law.” On the other hand, pietas is “that union of reverence and love to God which the knowledge of his benefits inspires.” Expounded here is something rather far removed from trajectories that find natural theology as their starting point—the idea of an irrefragable knowledge of God garnered apart from reverence and revelation, that is, a special and specific Word from God. Rather, Calvin speaks of the first step of pietas being, “to acknowledge that God is a Father, to defend, govern, and cherish us, until he brings us to the eternal inheritance of his kingdom.”
That true knowledge of God cannot be torn asunder from pietas and religio means, then, that overly-philosophical speculation about the essence or substance of God is necessarily ruled out. Calvin derides such pursuits as “Epicurean,” as “frigid speculations,” and admonishes us rather to seek out “what things are agreeable to his nature.”
Personally this resonates with me deeply; which is why Murphy’s chapter is so apropos in a book with the title Evangelical Calvinism. It is this embodied way of knowing God, by loving God that represents the proper kind of ‘pure religion’ and piety that Jesus himself claims sums up all of the Law and Prophets:
36 “Teacher, which is the great commandment in the Law?” 37 And He said to him, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ 38 This is the great and foremost commandment. 39 The second is like it, ‘You shall love your neighbor as yourself.’ 40 On these two commandments depend the whole Law and the Prophets.”
What this Calvinian mode towards knowledge of God kicks against, ironically, is any approach that would attempt to know God through discursive reasoning, or philosophical abstraction. What Calvin’s approach admonishes us to is to approach God through God in Christ en concreto (specific); through the realization that genuine knowledge of God is never an abstract academic endeavor, it always entails the particular and scandalous approach to God that only comes through the Lamb slain before the foundations of the world. In other words, genuine religion and piety, relative to the Christian, involves a committed and lively relationship with God; but one that is not initiated by humans in abstraction, instead one that is unilaterally provided for by the initiation and election of God in Christ. Some might consider this relational way for conceiving of knowledge of God as foolish and weak; but so goes the way of the Gospel.
What this all avoids is presenting a knowledge of God that is rooted, again, in philosophical speculation and even what counts today, most, as what it means to do good Christian evangelical theology. What we want to avoid, which Dag Hammarskjöld so eloquently describes is a presentation of a knowledge of the faith that in the end is perceptibly empty by the discerning and reflective human Christian or even non-Christian would-be knower. Note Hammarskjöld: “‘How many have been driven into outer darkness by empty talk about faith as something to be rationally comprehended, something “true”’. If we follow Calvin’s lead, according to Gannon, we won’t be ‘driven into outer darkness’ when coming to know God in Christ; instead because of union and participation in and from life in Christ we will be “irresistibly” drawn deeper and deeper into the winsome and ineffable inner life of God, in Christ, wherein an effervescent and luminous knowledge of God’s life, by experience (properly understood), will be ever increasing and ever inviting.
Leaving on a Personal Note
I honestly do not think this is the approach people in the 21st century evangelical church, particularly in North America and the West, are being provided with. Instead, contra Calvin, what folks are being fed is a pablum of religio and pietas that come in that name only. In other words, people are being encouraged, if they want to press deep into God, to engage with God from a philosophical and ‘natural’ approach to him. What makes this hard for folks to discern is that so much of what they are being fed has been conflated and couched in a Christian (i.e. Reformed) heritage that has this type of heart-warmed-over affectionate “piety” associated with it; but when that person digs deeper into the intellectual framework that is funding this “piety” what in fact they will find is a highly philosophical apparatus for knowing God that has more to do with the classical Philosophers of ancient Greece than it does with God’s Self-revelation in Jesus Christ.
It seriously agitates me that this is what counts as engaging with God for the evangelical Christian today. I blame institutions such as The Gospel Coalition, Together 4 the Gospel, and other associations of evangelicals for much of this; i.e. at least as this is making its way into the broader community of evangelical Christians in North America. We need to return to the sources, ad fontes, truly; but may that be understood to be genuinely rooted in God’s Self-revelation in Jesus Christ alone. May that be understood to be grounded in an actual framework that genuinely is relational and personal, and works from the “foundation” that the Triune God is indeed ‘the ground and grammar’ of all things; particularly and mostly of knowledge of Godself.
