I think we need to refine our language to more explicitly identify what is good with an act or sentiment's being aligned to the nature of God, to 'who God is'. God is, as Adam points out, the source and ground of all ethical thinking; but God is who he is (and defined by no referent). He is triune, of course, and it is only here that his ontological identity as 'love' and existential manifestation of that in all his acts and words can make sense; can be 'grounded' in the only absolute available. An absolute that steps around platonic conceptualizations to sheer demonstration of what is inherent in who God is and thus defines what is truly real. Deflections from this become a degeneration of what is truly real and represent its corruption.
