Starting a new series, on the Trinity.
No man can fully explain the Trinity, though in every age scholars have propounded theories and advanced hypotheses to explore this mysterious Biblical teaching. But despite the worthy efforts of these scholars, the Trinity is still largely incomprehensible to the mind of man.
Perhaps the chief reason for this is that the Trinity is a-logical, or beyond logic. It, therefore, cannot be made subject to human reason or logic. Because of this, opponents of the doctrine argue that the idea of the Trinity must be rejected as untenable. Such thinking, however, makes man’s corrupted human reason the sole criterion for determining the truth of divine revelation.
I think that last phrase is an interesting point to make; that if we assume that all things must fit our logical paradigms, then we are setting up ourselves as the final authority on everything. But what of things that are bigger than us?
