Peter Leithart, a fellow at New St. Andrews College, pastor of Trinity Reformed Church in Moscow, Idaho, and contributor to journals such as First Things and Touchstone recently posted an article titled "Too catholic to be Catholic." The article has been widely shared and discussed, provoking both approval and criticism from different groups of persons. Leithart followed up his article with a response to one common criticism; his response is titled "Israel, Idolatry, and Separated Brothers." A good evaluation of Leithart's argument, from a Catholic point of view, can be found here: "“Too catholic to be Catholic?” A Response to Peter Leithart."
