That's a good question, but I've actually come to see that apologetics in the New Testament, in contradistinction to how it is defined today in a handful of way by various evangelicals, wasn't so much about persuading other people about some specific proposition (or multiples thereof) than it was predominantly about defending one's faith in the face of social and legal prosecution (as a form of persecution).
Being that for the longest time, Christians in the U.S. have enjoyed legal hegemony, I'm kind of thinking (via my education in Social Science) that the certain kinds of evangelical notions have been mixed into various forms of apologetic praxis, with the result being that overall Christian witness suffers from having been formulated without the 'heat' of being a minority view.
Interestingly enough, it has come to my attention that I may have misread and slightly misapplied a small bit of Scripture, and this has come about because of a couple of fuller realizations, part of which got sucked into the vortex of the Hermeneutical Circle that I have constantly whirling around in my own praxis: 1) Julie Rays's use of that same piece of Scripture was misused by her in the OP podcast, and she used it at the beginning and the end to sandwich the podcast contents, and 2) I felt I had to do some further hermeneutical study via not only Penner but a few additional evangelical scholars and refigured the way in which I, too, have been associating the context of the same bit of Scripture and the way in which I had been understanding its meaning.
Y'know, when I first came onto CF years ago, my main goal was to be helpful to others and attempt to help them explore the Christian faith, with a sense of compassion for their pain and struggles. But I see I've kind of fallen off the horse over the past year or so as I've tangled with various pushy skeptics and allowed the political Marxist style vitriol to infect my own more moderate disposition.
And thanks for the tip on Hanlon. Interesting.
