CHRISTIANS' PROPER ROLE IN POLITICS DEBATED (St. Paul, Minnesota-AP) -- Syndicated columnist Cal Thomas says Christians should know that the world won't be saved through politics. Thomas debated Focus on the Family vice president Tom Minnery yesterday at Skylight radio's Inspo 2002 conference in St. Paul, Minnesota. Minnery said Christians should be "salt and light" in the culture. And he said rubbing salt in a wounded culture can sting sometimes. But Thomas said that when Christians seek the approval of political leaders, they surrender what should be their first allegiance -- to God.
