A question flowing from Ratzinger’s book

Cardinal Ratzinger also refers to the theological advances which our own country (the U.S.) is “producing”, specifically mentioning the advances in Scripture studies, stating that America “has made new breakthroughs in exegesis, in overcoming the one-sideness of the historical-critical method by so-called canonical exegesis, that is, by reading the Bible as a whole.”

Now, I know that there are efforts being made at getting past an over-emphasis on the historical critical methods, and that canonical exegesis is one of those attempts. But I can’t say that I know specific people and/or schools in the U.S. which have done so much work in this area as to be noticed by the Prefect for the Congregation of the Doctrine of the Faith. So, does anyone know whom the good Cardinal might be referring to in the field of canonical exegesis in the U.S.? Are they Catholics? Protestants? Both?
