The Rev. Virgil Brady says radical Islamists aren’t the only ones to blame for terrorism.

Radical Christians are to blame, too.

Brady, retired pastor at First United Methodist Church, 946 Vt., has self-published a new book, “Believe the Believable: Faith in the Face of Diversity.” He argues that terrorists are fueled, in part, by fundamentalist Christians who profess a faith that doesn’t accept diversity.

“The first chapter is probably going to be fairly radical to a lot of people,” Brady says. “It says certain parts of Christianity are contributing to a lot of the dislike and anger toward Americans, because certain Christians profess certain Christians are going to heaven, and everyone else is going to hell.”

It shouldn’t come a surprise, he argues, that those philosophies don’t foster much religious conversation.

“We’re all concerned about terrorism,” Brady says. “But we haven’t adequately addressed at least one aspect of terrorism. There are a lot of political and social causes. But we’re seen as a Christian nation, and when there are people saying their cherished beliefs are wrong, people aren’t going to like us, and they’re even going to hate us.”

That’s why, he says, mainline and liberal Christians need to solidify their faith and talk more about them, so that the rest of the world knows fundamentalist Christians aren’t the only Christian voices in the United States.

The same philosophy, Brady says, could help bring some former church-goers back to sanctuaries.
