Nikolai Bukharin – a Bolshevik revolutionary – discusses the need for not only economic liberation but also spiritual liberation of the working class and its party. He asserts that religion is a detriment to the workers’ struggle. He calls for a separation of church and state and religion as a private matter. Additionally, he states that schools must free education from capital and religion.

The worship of the souls of the dead rich was the foundation of religion…
The church was an organization of the bourgeois state…
The organs of the local workers’ authority shall have control over the schools, and shall not stint their energies in the matter of popular education, supplying to all the children and young men and young women all the knowledge which they need for a happy life.
