Do you remember your last science class? One of my favorite insights of science was the concept of "significant digits". For example, if you have a digital thermometer, and it tells you that the temperature outside is 82.1 degrees F and it seems to be rising 1 degree per hour, you can't necessarily project a temperature of 85.301247 at a certain future point in time. Why not? Because our measurements aren't that accurate. Sure, our calculators are that accurate; the formulas we're testing are (possibly) that accurate. But our measurements aren't. You started out with precision to 1/10th of a degree. By the time you run past your original level of precision, any further precision is unwarranted and probably misleading. It's a figment of your calculator's imagination. It's not a matter of whether your calculation is right; it's that you can't get out more precision than you had when you started.
Some of my difficulty with theological hair-splitting stems from the same reasoning. If we trust Christ, there are things we do know with certainty -- for example, we can know he will raise us up at the last day, because we have that plain and straight from a trusted source. It's much like knowing that it's 82.1 degrees outside, if we trust the thermometer.
My objection comes with things we are not directly taught. We have a curiosity that generally serves us well. We take what we are given and we start calculating. We get further than we ever would have if we had not started. So we calculate. And we keep calculating. Is God rightly understood as omnipotent, omniscient, and omnipresent? Well, that may be so, but that leaves out his love. How about one essence in three persons? I haven't heard a better explanation, but that's not quite the same thing as conclusive. Is Christ two natures in one person (Chalcedonian) or one new nature in one person (Coptic)? Are we really sure we have enough information directly about that to tell the difference?
I am willing to trust Christ to know God. But when we begin calculating things where we have no direct way to know, we should realize our limitations.
