Some of the best religion reporting in The New York Times appears in the Business Section, under the byline of Diana B. Henriques. Her latest, “Megachurches Add Local Economy to Their Mission” — with Andrew W. Lehren — is hardly news to those who pay attention to American religion, but she reports with attention to financial detail and sensitivity to church history and congregational politics that makes it stand-out journalism. The story, she reveals, is not the usual “gee-whiz, evangelicals are into marketing”; it’s about taxes, and who doesn’t have to pay them.
