Biblical inerrancy
On June 30, 2007, Cook retired, just prior to the official start of Biola's centennial celebration. He was one of California's longest serving university presidents. Cook was noted for his strong defense of Biblical doctrine, including the key doctrine of Biblical inerrancy. Under Cook's leadership, Biola grew tremendously from a small Bible college to one of the largest evangelical universities in the nation, with nearly 6,000 total students.
