纯洁性是马克思主义政党必须遵循的价值理念,更是无产阶级政党的一贯追求。在保持无产阶级政党思想纯洁性的问题上,马克思恩格斯坚持:用科学社会主义理论武装共产党人;对要求入党的分子在思想上严格要求,使其在思想上入党;批判、揭露和消除各种“冒牌货”。这些观点和实践对我们今天构建马克思主义学习型政党长效机制,巩固马克思主义意识形态的主流阵地,推动党性修养和党性锻炼常态化有着重要的现实意义。 Purity is the value concept that Marxist parties must follow, and it is the consistent pursuit of proletarian parties. On the issue of maintaining the ideological purity of the proletarian political party, Marx and Engels insisted: Arming the Communists with the theory of scientific socialism; demanding strictly the ideological requirements of the elements that are required to join the Party so that they can join the party ideologically; and criticizing, exposing and eliminating various “Counterfeit goods ”. These views and practices are of great practical significance for us to build the long-term mechanism of Marxist learning-type parties today, consolidate the mainstream positions of Marxist ideology, and promote the normalization of the Party spirit and the Party spirit.
