Theological Symbiosis
As I was walking to work this morning, it occurred to me to conjecture that “liberal” theologies err to the extent that they neglect their symbiotic relationship with ordinary, historic, “orthodox” (by which I don’t necessarily mean “what contemporary soi-disant orthodox Anglicans mean, but something more like “broadly-agreed-upon”) theology. I’d say “liberal” theology is parasitic on historic orthodoxy, but there’s no way to do that without giving the impression that I mean it pejoratively, which I don’t.
That is, I conjecture that “liberal” theology flourishes to the extent that it provides an alternative articulation of theological points alongside what non-“liberal” theologies assert. When “liberal” theology begins to elbow aside or suppress non-“liberal” theology — when it asserts a sort of Whiggish triumphalism over the allegedly obsolete, irrelevant formulations of hidebound blah blah blah — it cuts off the vitality of the partner without whose continuing strength, the “liberal” alternative loses its coherence. Thus, if I’m on the right track, it’s positively in the interests of “liberal” theologians to support strong education in the basics of historic theology; that’s the juniper that supports their mistletoe, or the anemone that shelters their clownfish.
On this account, “conservative” theologies likewise depend symbiotically on historic orthodoxy. And by the same token, the more narrowly one defines the “one true and eternal faith” of a “conservative” theology, the less wholesome that theology becomes; dry rot sets in, and (once again) the tree collapses under the weight of its symbiont. The leading difference in these two cases derives from the rationale given for choking off the host: in the case of the “conservative” symbiont, the main trunk has become too tolerant, has deviated fatally from the correct doctrinal formulae.
When I propose this, I do not mean to refer to a particular present case, e.g. sexuality. All the specifics of cases would require argument relative to their specifics, and although I disagree with many “conservative” arguments regarding sexuality, I don’t posit that they err simply by drawing a line and not “tolerating” disagreement on this topic. Rather, the more precise way to conduct the “conservative” argument (according to me, to whom no one is obliged to listen) would be to begin by allowing that breadth and diversity and flexion characterize the church through history, and that theological positions such as that which I advocate nonetheless fall outside the bounds of what the church can permit. Now, some theologians do couch their arguments that way (generally), and I respect the care that reflects. I still disagree, but it’s an argument within which we’re really disagreeing about a real thing. A considerable number of theologians, on the other hand, espouse a perspective on the church’s teaching that unduly throttles the circulation of nourishing theological ideas — let us say, by making one particular doctrine of the atonement an essential hallmark of sound theology — such that the church’s growth and strength suffer. “We only need Vitamin D! All those other vitamins are a snare and a delusion!” One need not adopt an absolutism of one source of nourishment in order to dispel claims that other diets are unbalanced (if indeed they are).
It’s harder to explain to “liberal” theologians that I disagree with them, because often (as in the case of sexuality) we seem to be agreeing. Still, where a modernised church proclaims its triumph over its own past’s ignorance, I politely step out of lockstep and return to converse with less up-to-date colleagues. The fact that the church’s mind changes in various ways over time (how could it not?) doesn’t mean that its former outlook is benighted, foolish, uncritical, anachronistic, or “fundamentalist” (a word that tends to function overwhelmingly as a term of abuse, not as a clearly-defined explanation of a basis for disagreeing). Most “liberals” take some things literally and they ignore or rationalize other things; most “conservatives” likewise take some things literally and soft-pedal or rationalize others. Most “liberals” and “conservatives” both construe certain theological premises as “fundamental.” Almost all of those definitions obscure the possibility that the definer in question might, possibly, be wrong — might indeed need fellowship with, communion with, a broader range of alternatives than she or he is willing for his/her definition to permit. (Again, there will be boundaries — the problem arises not from drawing boundaries, but from refusing to draw boundaries humbly, charitably, and subject to change or correction.)
The strength of good theology draws on more than simply partisan teaching. If any version of “liberal” or “conservative” theology is sound, it will be able to draw strength from the historic breadth and variety and consistent emphases of the church’s teaching. At the very least, the distinct “l”/“c” theology will benefit from its adherents and exponents being able clearly and specifically to explain the pattern of continuities and exclusions that they propose. And new believers will be very much better served by learning sympathetically the church’s historic basics first, before they learn ways that their contemporaries have characterized topics more narrowly.
