James K.a. Smith said this quote

We have created youth ministry that confuses extroversion with faithfulness. We have effectively communicated to young people that sincerely following Jesus is synonymous with being 'fired up' for Jesus, with being excited for Jesus, as if discipleship were synonymous with fostering an exuberant, perky, cheerful, hurray-for-Jesus disposition like what we might find in the glee club or at a pep rally.

~ James K.a. Smith

It's not that we start with beliefs and doctrine and then come up with worship practices that properly express these (cognitive) beliefs; rather, we begin with worship, and articulated beliefs bubble up from there. Doctrines are the cognitive, theoretical articulation of what we understand when we pray.

~ James K.a. Smith

By using repetition, images, and other strategies - all of which communicate truths in ways that are not cognitively or propositional - marketing forms us into the kind of persons who want to buy beer to have meaningful relationships, or to buy a car to be respected, or buy the latest thing to come along simply to satisfy the desire that has been formed and implanted in us. It is important to appreciate that these disciplinary mechanisms transmit values and truth claims, but not via propositions or cognitive means; rather, the values are transmitted more covertly...This covertness of the operation is also what makes it so powerful: the truths are inscribed in us through the powerful instruments of imagination and ritual.

~ James K.a. Smith

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.
