James Chastek, Integral truth
Mr. Chastek compares theological truth with food and relates both to multiple ends. G-L is making a point though about the epistemology of those supporting the development of a new, up-to-date theology. If theology is not true, then how can it benefit or aid modern man and his vexations? Do we know God via things? Or do we know God through our ideas?
We could also ask the question of whether theology is more speculative or practical in nature.
