Radical Orthodoxy and Lonergan

I was searching for someone engaging Radical Orthodoxy and Lonergan, and here is one such: Christopher McMahon, "Theology and the Redemptive Mission of the Church: A Catholic Response to Milbank's Challenge." Heythrop Journal 51/5 (2010) 781-94. I have just glanced through the article, but there does not, however, seem to be any reflection on the natural-supernatural distinction.
