“For with thee is the fountain of life: in thy light shall we see light” is the voice of what I’d call integral faith.
“God said it, I believe it, that settles it” is the voice of what I’d call accessory faith.
The former seeks to know reality. The latter seeks to know the rules.
This is entangled in my mind with my notional rejection of divine command ethics in the form articulated by Duns Scotus, which sometimes seems pandemic, but articulation of which I have long found jarring. Yet I’m sure better people than me have, after due thought, endorsed divine command ethics, even in the rigorous form that holds that God could reverse every command of the second table of the Decalogue, making murder, adultery and theft mandatory. And I haven’t given it rigorous thought — more like visceral rejection.
