Mr. Calhoun was the founder of the Mt. Olive Tape Library, a massive collection of recordings which Mr. Calhoun acquired over the course of some thirty years. The collection reflects the personal quest of Mr. Calhoun for a balanced education in Reformed Theology. The speakers included in the tape library have been scrutinized for their faithfulness to the Bible.
In 2006, the assets of the Mt. Olive Tape Library, Inc. were transferred to the care of Greenville Presbyterian Theological Seminary. They are no longer "tapes" filling an entire room at the seminary but are now digitized electronic files available at the seminary's channel at SermonAudio.com. The messages enable students and others to access some of the best Reformed preachers as they pursue their study of Reformed theology. Much of the digitizing was done by GPTS Media Director Jeff Downs.
The 10-year-old Greenville Seminary & Mt. Olive channel at SermonAudio now has more than 5,100 sermons and lectures (and now our podcasts), and is the most visited channel on the extensive SermonAudio web site.
