HONG KONG — A secretive Chinese court sentenced one of the country’s best-known Christian voices and founder of one of its largest underground churches to nine years in prison for subversion of state power and illegal business operations, according to a government statement released on Monday.

Wang Yi, the pastor who founded Early Rain Covenant Church, was detained last December with more than 100 members of his congregation as part of a crackdown on churches, mosques and temples not registered with the state.

While most of Mr. Wang’s parishioners, including his wife, Jiang Rong, were eventually released, Mr. Wang never re-emerged from detention.

As part of his sentence, he will also be stripped of his political rights for three years and have 50,000 renminbi, or almost $7,200, of his assets seized, according to the statement.
