Religion still has no role to play in communist politics
Freedoms end when one joins the party, but some have become closet believers
While America's "Don't Ask, Don't Tell" policy - used to deter openly gay men from joining the US Army - is a thing of the past, its Chinese political variant remains firmly in place.
"Those who believe in religion shall not join the Chinese Communist Party," said Zhu Weiqun , director of the Committee for Ethnic and Religious Affairs of the Chinese People's Political Consultative Conference, in a recent interview.
He was repeating one of his opinions that was published in a party-backed magazine in 2011 when he was a top official for the United Front Work Department of the Central Committee of the Communist Party.
According to Zhu, Marxism, the lifeblood of the party, is based on dialectical materialism.
Allowing religious followers into its fold will divide the party ideologically and theoretically, as it implies the uneasy coexistence of idealism and materialism and of theism and atheism.
A party that lost its ideological and theoretical vigour would be "unable to promote the great cause of socialism with Chinese characteristics", he added.
