Contemporary Evangelical Rahnerianism
Theological views on the Trinity greatly affect most aspects of Christian faith and life. For example, in terms of basic Christian belief, the current trinitarian debate about the subordination of God the Son to God the Father has great significance for Christology. In terms of Christian life, the inner life of God the Trinity has been argued to be the basis for various social, familial, and ecclesial relationships and practice. Much of this theology and its implications revolve around the methodological use of Rahnerâs Rule (RR). This axiom, RR, is defined as follows in Karl Rahnerâs classic work The Trinity: âThe âeconomicâ Trinity is the âimmanentâ Trinity and the âimmanentâ Trinity is the âeconomicâ Trinity.â
The positive aspect of this maxim is that it reconnects the human experience of God in history with the immanent Trinity, thus narrowing any perceived gap between the Trinity and faith. A second positive outcome is that if all theology is carried out with RR in view then all branches of theology will necessarily be in close relationship to trinitarian theology. RR has become so significant that Vanhoozer recently stated, âOne of the most important present-day litmus tests for theologians pertains to how far one accepts (or understands!) Rahnerâs Rule.â Evangelicals are no exception to this need to deal with RR, and in fact many Evangelicals with a high view of Scripture do employ RR as a key theological norm. However, amongst Evangelical theologians RR is employed in different ways in order to support their various proposals. For example, despite the fact that Lethamâs The Trinity, and Ericksonâs God in Three Persons, are regarded as two of the most significant conservative Evangelical works on the Trinity, these works come to opposite conclusions on various issues based upon different interpretations of RR. This is not an isolated phenomenon. Rather, this highlights two reasons for the difficulty that RR poses. The first is that it contains an âinherent instability.â As Sanders notes: âRahnerâs Rule . . . lean[s] sometimes toward a more strict and total identification of economic and immanent Trinity, and sometimes toward a more carefully circumscribed account of the relationship between them.â Secondly, RR is âdifficult to falsify and . . . difficult to confirm.â Struggles with RR and its attendant issues are not limited to the English-speaking world. In German-speaking scholarship, Stolinaâs 2008 work â»Ăkonomische« und »immanente« TrinitĂ€t?â called for a re-conception of the relationship between the economic Trinity and the immanent Trinity. A representative of French scholarship is Dunard, who argues that Rahner never expected his rule to be interpreted as a univocal norm.
Our current context, in which RR has been interpreted in varying ways, demonstrates the need for a decisive Evangelical methodology which a view to assessing the validity of RR, and any particular use of it. Evangelicals with a high view of Scripture tend to choose either of two approaches to RR. These can be usefully described with the application of Rauserâs designations. There is firstly the âstrict realist readingâ (SRR) of RR, secondly, a âloose realist readingâ (LRR) of RR. Other designators for these two approaches include Sandersâ designations: the âradicalizersâ and the ârestrictivists.â The approach known as the ârestrictivistâ approach has also been called the âmethodologicalâ and âepistemologicalâ reading of Rahnerâs Rule. Coppedge employs the language of âmethodologicalâ and âontologicalâ to differentiate two approaches to the Rule. He favors the âmethodologicalâ approach, which is the one taken by those whom Sanders would designate as ârestricters.â Coppedge writes: âIt is probably best to see Rahnerâs insight as a methodological one, so the economic Trinity is understood as revealing the ontological Trinity. To take his rule in an ontological way might blur the distinction between the being of God and the doing of God. If that should happen the focus is on what God does in relation to creation and leads to a functional understanding of the Trinity. The result would be not enough attention given to the relationship of the triune God within himself.â
What Coppedge designates as âmethodologicalâ is equivalent to what others have called the âepistemologicalâ interpretation of RR. A representative of the epistemological approach to RR states this view as: âThe ontological Trinity is the ground of being for the economic Trinity and the economic Trinity is the ground of cognition for the ontological Trinity.â The rationale underlying this statement is that âone needs to acknowledge the ontological Trinity as the ground of being for the economic Trinity. If it were not for the ontological Trinity, there would not be the economic Trinity. The ontological Trinity that might be completed by the economic Trinity is not the ontological Trinity in sensu strictu. Only when there is the ontological Trinity is there the economic Trinity through which we can recognize and understand God.â
There has been confusion about how to interpret the Rule within Roman Catholic circles since Rahner penned it, and Evangelical theology has not been exempt from this phenomenon. Evangelical theology has not ignored the role of RR within the âtrinitarian renaissanceâ of the twentieth century. On this topic KĂ€rkkĂ€inen (who is a contemporary Evangelical theologian working on the Trinity) states that, âwhat is exciting about the current trinitarian renaissance is that questions and issues old and new are being re-visited and re-examined. Far from being an archaic doctrine, the Trinity has proven itself to be a source of vital debate and spiritual renewal.â In the context of explicitly speaking about RR, KĂ€rkkĂ€inen makes clear the priority of the correct understanding of RR when he says, âWhile a number of issues are being debated in contemporary trinitarian theology . . . at the heart of the discussion stands the question of the relationship between the economic and the immanent Trinity.â For KĂ€rkkĂ€inen, the importance of the interpretation of RR is not limited to the economic/immanent question alone: âThe centrality of the issue is accentuated by the fact that the way one attempts to resolve this question is based on and has implications for several other key topics such as how to establish the oneness of God and how to defend the freedom of God.â
Rauserâs three possible readings of RR, and the two possible readings by Sanders (above), point out the fact that a neat division of the readings of RR into either an epistemological or an ontological reading is insufficient for Evangelicals because their foundations have not been demonstrated by Scripture. Rauserâs LRR is equivalent to Sanderâs ârestrictivistâ view, which affirms a strong epistemological connection between the economic and immanent Trinity. However, what Sanders labels as the âradicalizing viewâ ...
