The discussion following last week's post (concerning when to bring up the trinity) revealed that some might object to the premise of the question. The question seemed to presuppose that one should bring up doctrinal topics one-by-one. However, this is not the only way to think, write and teach theologically. So, let me step back and raise the prior question: how should organize doctrines?
Note that I am restricting this question to doctrinal theology, recognizing that there are many other aspects to the theological task (exegetical, historical, practical, etc.). However, I am narrowing our attention to the question of doctrinal organization not only for the sake of time and space but also because doctrinal theology is especially interested in the question of the organization of topics. This is one reason why doctrinal theology is also called "systematic" theology. This concern arises from the fact that organizational decisions can have material consequences. So this is not only an aesthetic or pedagogical question (though it includes these concerns).
A few organizational options come immediately to mind. Note that these may be overlapping, and so it is no surprise that some of the greatest minds in Christian history transcend the boundaries of these categories. But thinking about the basic alternatives is a good exercise.
(1) Topical. A long-standing way of organizing doctrines for teaching and writing is to move one-by-one through the main topics of doctrinal theology. This is also known as the Loci method (most likely traceable to Philip Melanchthon's Loci Communes). The strength of this approach is its clarity of presentation and balanced focus on numerous theological questions. The risk is that one may disconnect the various topics from one another and thereby fall short of a robustly systematic theology.
(2) Foundational. Another approach is to take either a specific doctrine or a particular perspective (philosophical, contextual, etc.) as one's starting point. This starting point might be located at the beginning of a theological text or course, and/or may be reiterated throughout. The point is that every doctrine is at least controlled by if not derived from this starting point. The strength of this approach is the consistency that tends to flow from it. The danger is that one may choose the starting point point poorly. In fact, even a good starting point can spoil doctrines by exercising tyrannical control over one's thought.
(3) Architectonic. One more way to organize doctrines is to interrelate them to one another in a larger superstructure. This could be done by means of broad categories which include doctrines, perhaps placing doctrinal topics in parallel sequences. Such an architectonic organization could perhaps be drawn by a diagram with major categories and sub-categories within each category. The advantage here is all the doctrines would be interrelated without one doctrine or perspective controlling every detail. The disadvantage is that some important topics might slip through the cracks because they do not fit neatly into the architecture. Furthermore, one might become intoxicated by the aesthetic appeal of certain organizational decisions to the point of distraction from the main task of expositing Christian doctrine.
