He was also ordained as a Baptist minister in 1983.
He also founded Patrick Henry College, which opened its doors in 2000, specifically for home-schooled Christian students. He held the positions of president and professor of Government from 2000 to 2006. Farris resigned his position as president of HSLDA to take on these new roles. In March 2006, Farris stepped down from the position of president to become chancellor of the college.
Farris is also the author of several books on homeschooling and family as well as the book From Tyndale to Madison, published in 2007. He has also written a few novels.
Education Week named Farris one of the most significant 100 "Faces of the Century."
In 1993, Farris ran unsuccessfully for lieutenant governor of Virginia and was defeated by Democrat Don Beyer — 54-46 percent. However, fellow Republicans George Allen, Jr., and James Gilmore were elected on the same ballot as governor and attorney general, respectively. Farris' close connection to conservative leaders like Jerry Falwell of the Moral Majority, Pat Robertson of the Christian Coalition, and Phyllis Schlafly of the Eagle Forum, stirred deep-seated feelings about religion and politics. These concerns inflamed by negative ads by Beyer to portray him even more radically, likely caused alienation of enough moderate voters to lose him the election. There was also soreness among Virginia Republicans for U.S. Senator John Warner's lack of support for Farris.
Farris was the founder and chairman of the Madison Project, a political action committee. He is also the founder of Generation Joshua, an organization for the mobilization of Christian youth to participate in politics and get out the vote. In 2007, he founded ParentalRights.org, a parental rights advocacy group.
