LYNCHBURG, Va., May 19 -- Former House Speaker Newt Gingrich decried a "growing culture of radical secularism" Saturday morning as he hailed the life of Liberty University's late founder, the Rev. Jerry Falwell, in an address to the school's 2007 graduating class.

In a speech heavy with religious allusions but devoid of hints about his presidential ambitions, Gingrich drew applause from the graduates and their families in the school's 12,000-seat football stadium when he demanded: "This anti-religious bias must end."

"In hostility to American history, the radical secularists insist that religious belief is inherently divisive," Gingrich said, deriding what he called the "contorted logic" and "false principles" of advocates of secularism in American society.

"Basic fairness demands that religious beliefs deserve a chance to be heard," he said during his 26-minute speech. "It is wrong to single out those who believe in God for discrimination. Yet, today, it is impossible to miss the discrimination against religious believers."
