In youth he was beset by a number of medical difficulties, the most serious of which was a lifelong platelet problem that made it difficult for him to stop bleeding, a condition similar to hæmophilia.
While attending Westmont College he began writing for the Chalcedon Foundation of Rousas J. Rushdoony and soon came to admire the latter's strong Calvinistic convictions.
In 1975, after receiving ordination in the Orthodox Presbyterian Church, he became an associate professor of Apologetics and Ethics at Reformed Theological Seminary (RTS) in Jackson, Mississippi.
