[T]here is the question of the relationship of the revolutionary party to religious workers. Any such party operating in a country where religion remains strong among the mass of the population, which is much of the world, must reckon with, indeed count on, the fact that the revolution will be made by workers of whom many will still be religious. The vast mass of workers will be liberated from their religious illusions not by arguments, pamphlets or books, but by participation in the revolutionary struggle, and beyond, in the building of socialism. In such a situation it is incumbent on the party to ensure that religious differences, or differences between the religious and the non-religious, do not obstruct the unity of working class struggle. Moreover, insofar as the party becomes a truly mass party, leading the class in its workplaces and communities, it will inevitably find in its ranks a layer of workers who remain religious or semi-religious. To reject such workers because of their religious illusions would be sectarian and non-materialist. It would be to share the religious/idealist mistake of regarding religion as the most important element in consciousness and consciousness as more important than practice. At the same time, the party must not become a religious party, or party whose policy, strategy or tactics are shaped by religious considerations. Revolutionary victory requires that the party should be guided by the theory that expresses the collective interests and struggle of the working class, namely Marxism. Therefore the party must ensure that on this matter it educates and influences its religious members rather than vice versa.
