NANJING, China — The factory looks like it could be any plant in this export-driven nation. Hundreds of Chinese workers huddle over loud machines churning out large orders for customers at home and abroad.

But what they're making might surprise you: Bibles.

As Tibetan monks grab headlines protesting the lack of religious freedom under Chinese rule, a booming Bible industry is turning the world's biggest atheist nation into the world's largest supplier of the Christian book.

Chairman Mao once said, "Our God is none other than the masses of the Chinese people," but at Nanjing Amity Printing Co., China's only state-sanctioned Bible printer, little time is wasted pondering the metaphysical mismatch.

"We are printers," said Li Chunnong, the general manager of the plant, which has about 500 employees. "As long as somebody legitimate sends us an order, we will print them."

This pragmatic mindset has contributed to the company's staggering growth. Since its first Bible rolled off the presses two decades ago, Amity has printed more than 50 million copies in 75 languages and exported to more than 60 countries.

The company is on its way to becoming the biggest Bible factory in the world, cranking out

12 million copies a year.

"The Bible is probably the best-selling book in the world," Li said. "People need spiritual fulfillment. There is a huge demand for what we do. We have certainly benefited from that phenomenon and will not let the market slip from our hands."

This kind of talk was almost unimaginable just a generation or two ago. During the radical years of the Cultural Revolution, from 1966 to 1976, just about the only reading material the Chinese people had was the Little Red Book of Mao Tse-tung's quotations — certainly not a big black book of Jesus' parables. Demonized as spiritual pollution, copies of the Bible were confiscated and burned.

The dawn of market-oriented reforms in the late 1970s and early 1980s brought a spiritual reawakening, with bustling Buddhist and Taoist temples and the opening of the first state-sanctioned church in a nation where Christianity is a minority faith.

An estimated 30 million Christians worship in government-approved churches that fall under the control of religious "patriotic associations." Tens of millions more are said to pray in underground outlets.

The renewed demand ran into a shortage of teaching material.

The first people who dared to print the Bible again were members of the Chinese People's Liberation Army. But the military press with its outdated facilities was ill-suited for the particular demands of the Bible, which requires lightweight paper to remain easy for people to carry around.

Still, the army press cranked out about 3 million copies before Amity broke into the market.

Today, more than three-quarters of Amity's Bibles are printed for domestic consumption.

Founded in 1988, the company is a joint venture between a Chinese Christian charity and the British-based United Bible Societies. The venture raised $5 million from United Bible Societies chapters around the world and built a factory on the outskirts of this ancient city formerly known as Nanking.

Peter Dean, Amity's production adviser, said the United Bible Societies does not proselytize at the plant, insisting its function in Nanjing is purely business.

"We have the same structure as a Motorola or a Philips," said Dean, a New Zealander who has worked with the company in China since 1991. "They make cell phones and TV tubes, and we're producing Bibles."

Anybody can buy a Bible in China, but only through a state-run church.

Visitors to China caught smuggling in copies face stiff penalties. Last year, the leader of an underground church accused of illegally printing and distributing thousands of Bibles completed a three-year prison term.

Beijing Olympics organizers recommend that spiritually inclined international athletes attending the games in August bring only one Bible for their personal use if they are worried about getting into trouble. Should they forget theirs, a Bible will be provided free, courtesy of Amity.

Because everything at the factory, including the state-of-the-art equipment and the extra-thin printing paper, is donated, Amity has a decided price advantage over potential competitors overseas. Its Bibles sell for as low as $1.35 for a pocket edition and $2.10 for a hardcover.

All proceeds, Dean said, go back to the company's charity arm to fund social programs for the rural poor in China and help local churches. He declined to provide specifics.

About 21 percent of Amity's production is exported — to Africa, Europe, Asia and the Americas. Besides translations in exotic languages, including Swahili and Slovak, it produces a Braille edition (nine blind workers were hired to supervise production).

Manager Li's crowded office brims with all shapes and sizes of the foreign gospel. He says he is too busy to read the book to which he has devoted 20 years of his life.

Instead, he says, he is preoccupied with the quality and variety of the product.

"Here is a Zulu Bible," he said, picking up a bright pink book with a cover that sparkled like broken mirrors. "Some people may want to throw up just looking at this color. Others see it as a potential best-seller, especially if you market it with a pair of pink high-heeled shoes."

All this seemed farfetched two decades ago when Amity opened its plant on farmland donated by the government. As part of the deal, the company had to find jobs for the 320 residents. None had any experience running a printing press or familiarity with the Bible.

"Before I came to work here, I had never heard of the Bible," said Yi Shuhong, 40, a 20-year employee.

Like many co-workers her age, her many years of exposure to the Bible at the factory helped interest her in Christianity.

Those who have converted said they were won over by proselytizers who came to their homes and who perhaps believed that the workers' Bible-related jobs made them more willing to listen.

"No one in my family believes in God," Yi said. "But they are not against me for converting."a
