KOUNTZE, Tex. — In a barrage of recent e-mails, telephone calls and letters to his office, Kevin Weldon has been called some of the worst things a Christian man in this predominantly Christian town can be called: un-Christian, and even anti-Christian.

“I’ve been in this business a long, long time,” said Mr. Weldon, the superintendent of the 1,300-student school district in Kountze, northeast of Houston. “People that know me know how I am. Even though I got those things, I’m going to be honest with you, this may sound very flippant, but it just went in one ear and out the other.”

Mr. Weldon, 53, is in a position that few superintendents in small-town Texas have found themselves: taking a stand on religious expression that has put him at odds with the majority of his students and his neighbors, not to mention the governor, the attorney general and, some in Kountze believe, his God.
