When Hong Kong's largely peaceful pro-democracy protests turned violent last summer, it drove a wedge through every section of society, dividing friends, families and also worshipers at its more than 1,500 churches.

Most people in Hong Kong follow some form of Buddhist, Taoist or other traditional Chinese religion, but the former British colony has about 900,000 practicing Christians, about 12 percent of the population according to government figures, split almost evenly between Roman Catholic and Protestant faiths. There is no consensus among them about the protests or China's tightening grip on the city.

Canaan Wong, Blesson Chan and Kristy Chan, all in their mid-20s, are part of a group of about 40 people who in late June quit their positions as mentors and teachers at the evangelical Tung Fook Church, because they said they felt pressure from senior church leaders to keep quiet about political matters.
