The first three responses reminds me of the title of a thread I made a while back on this forum: "Go Forth, And Make Gyros For All Nations"
Based on my admittedly limited reading of him, I think St. Thomas Aquinas is probably as close as any traditional writer gets to what I'm thinking of, good point. I'm not sure about St. John of Damascus or not, I've read his Exact Exposition of the Orthodox Faith, but that doesn't strike me as being the same as what people like McDowell are doing.
St. John of Damascus > anything you've read
Get his "Fountain of Knowledge" (through CUA Press) and read his book on philosophy and logic, then re-read "An Exact Exposition." Once you get where he's coming from philosophically, you'll see that his arguments are rock solid.
As someone who is a Protestant, let me say that I have noticed an absence of current
Orthodox writers on these big issues; but that's not a slam against Orthodoxy at all. It could be that being secluded in the West has kept me from such authors.
Regardless, I am partial to Swinburne and Engelhardt, or Kreeft and Beckwith (on the Roman side), but still, I don't see any popular level "apologetics" coming from the Orthodox camp.
But in all fairness, I've gotten more out of the Church Fathers, specifically Sts. Cyril of Alexandria, Basil the Great, John of Damascus, John Chrysostom, Gregory of Nazianzus, and Gregory of Nyssa. So it's a trade-off.
