The Green Bible, which has been endorsed by secular groups such as the Humane Society and the Sierra Club, shows people that "God is calling us to care for the world around us," said Rusty Pritchard, editor of Creation Care Magazine, a publication for evangelicals.

Other evangelicals are concerned the Green Bible will mislead Christians because it does not interpret Scripture literally, said James Taylor, a founding elder at Living Water Christian Fellowship in Palmetto, Fla.

"These groups don't have a religious focus; they have a desire to spread their environmental message," Taylor said of the essayists who contributed to the Green Bible, which contains a foreword from Anglican Archbishop Desmond Tutu.

An estimated 25,000 copies have been sold by HarperOne since the book's release in October, The Arizona Republic reported Monday.
