Only a handful of critics go beyond merely asserting the charge of incoherence of the Trinity and provide logical arguments to support their claim of incoherence.
In general, a logical demonstration of incoherence may include the following steps: Given propositions P and Q, one may demonstrate a contradiction between these two propositions by positing another proposition R (which is presumably true) such that Q and R taken together will lead to a fresh proposition S which clearly contradicts P. Conversely, one may claim that P and Q are coherent if S is evidently coherent with P. For examples of such an exercise, I refer to my earlier articles
In any case, the task of logical demonstration is not so straightforward. Note that we assume that the propositions are clear and unambiguous. For example, we assume that the particular statement P or Q adequately and accurately and precisely represents essential aspects of God. But the fact is, we do not have any clear account of human nature that has gained consensus, let alone an account of divine nature. In reality, propositions P and Q are read differently (though implicitly) by different protagonists in logical debates. Continue reading “Limits to Logical Analysis in Doctrinal Debates”
