“It is precisely this refusal of the Cartesian paradigm that characterizes Radical Orthodoxy, which seeks to reanimate the account of knowledge offered by Augustine and Aquinas. On this ancient-medieval-properly-postmodern model, we rightly give up pretensions to absolute knowledge or certainty, but we do not thereby give up on knowledge altogether. Rather, we can properly confess that we know God was in Christ reconciling the world to himself, but such knowledge rests on the gift of (particular, special) revelation, is not universally objective or demonstrable, and remains a matter of interpretation and perspective (with a significant appreciation for the role of the Spirit's regeneration and illumination as a condition for knowledge). We confess knowledge without certainty, truth without objectivity.”

“We confess knowledge without certainty, truth without objectivity.”

“By calling into question the very ideal of a universal, autonomous reason (which was, in the Enlightenment, the basis for rejecting religious thought) and further demonstrating that all knowledge is grounded in narrative or myth, Lyotard relativizes (secular) philosophy's claim to autonomy and so grants the legitimacy of a philosophy that grounds itself in Christian faith. Previously such a distinctly Christian philosophy would have been exiled from the 'pure' arena of philosophy because of its 'infection' with bias and prejudice. Lyotard's critique, however, demonstrates that no philosophy - indeed, no knowledge - is untainted by prejudice or faith commitments. In this way the playing field is leveled, and new opportunities to voice a Christian philosophy are created. Thus Lyotard's postmodern critique of metanarratives, rather than being a formidable foe of Christian faith and thought, can in fact be enlisted as an ally in the construction of a Christian philosophy.”

“Of what use is it that we know the truth, if we lack its spirit? Our knowledge, in this event, becomes a condemnation to us, failing to bear fruit. It is not sufficient that we know the truth, but we must be humble with this knowledge possess the spirit to actuate us to good deeds. Baptism, as well as all other outward ordinances, without the spirit accompanying, is useless. We remain but baptized sinners.”

“Our Christian faith - and correlatively, our account of apologetics - is tainted by modernism when we fail to appreciate the effects of sin on reason. When this is ignored, we adopt an Enlightenment optimism about the role of a supposedly neutral reason in the recognition of truth.”

“Knowlege of God without knowledge of man's wretchedness leads to pride. Knowledge of man's wretchedness without knowledge of God leads to despair. Knowledge of Jesus Christ is the middle course, because by it we discover both God and our wretched state.”

“If in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics...”
