Bob Fu says hundreds of churches continue to be torn down, and that Christians have been beaten up and sent to hospital because they were holding on to crosses that military police were trying to take from their churches.
He added that even state-sanctioned churches, which are monitored by the Chinese authorities and include government messages, are facing persecution.
Bob Fu told Premier: "In the past eight or nine months or so, China is experiencing the worst persecution since the time of the cultural revolution.
"In Chinese church we have a famous saying: one more Christian, one less criminal, one more church, one less prison...But the Chinese Communist Party still regard Christianity and Christians as a threat; as an enemy.
"Several times the government mobilised over 1,000 military police, surrounded a church in the early morning...and started beating up these peaceful brothers and sisters who were just praying over there."
Elsewhere, pro-democracy protests are still being held in the Hong Kong district of China, because China has preselected the candidates they can vote for in their 2017 elections.
Protestors have agreed to hold formal talks with the Hong Kong government after the protest numbers fell from hundreds of thousands of people to just hundreds.
