"Hahn is one of a few seminary-trained, apparently well-educated Protestant ministers who have joined the Roman Catholic Church over the last few years."
This statement is wildly inaccurate. There has been a significant movement of ministers, theologians and intellectuals into the Catholic Church from other faith traditions in recent years. This is not the first time this has happened; however, a number of these individuals are making highly significant contributions to the Church. These individuals have brought tremendous gifts from previous faith traditions, and utilized those gifts in the service of the Church.
In the case of Scott Hahn, he was a Presbyterian minister who joined the Catholic Church several years ago. Dr. Hahn works very hard to convey his deep love of Scripture to fellow Christians. His work includes a number of books on Scripture, his online Bible Study Course (
http://www.salvationhistory.com/), a very enjoyable radio program (Scripture Matters,) his work as a Scripture Professor, and weekly Bible studies for college students in his home. There have been a number of other Presbyterian ministers who have joined the Catholic Church in recent years, and many of them have undertaken very fruitful ministries for building up the Body of Christ.
Among other ministers that have joined the Catholic Church, there are several whose writings are routinely posted and enjoyed by a wide range of readers here on FR, including both Evangelical and Catholic Christians.
