保持党的先进性纯洁性是一个关系马克思主义政党生存、发展、壮大的根本性问题,是“建设一个什么样的党和怎样建设党”的长期任务和永恒课题。早在延安时期,毛泽东就向全党明确指出,我们要建设的是“一个有纪律的、思想上纯洁的、组织上纯洁的党,合乎统一的标准的党”。回顾我们党90多年的奋斗历史,保持先进性纯洁性始终是我们党矢志不渝追求的目标。这方面的历史经验为我们党在新形势下应对各种考验、战胜各种危险,增强自我净化、自我完善、自我革新、自我提高能力提供了重要启示。 Maintaining the advanced nature of the party is a fundamental issue concerning the survival, development and expansion of Marxist political parties and the long-term task and eternal task of “building a party and how to build the party.” As early as the Yan’an period, Mao Zedong clearly pointed out to the entire party that what we want to build is a party that is “disciplined, purely ideologically pure and purely organized, and in conformity with a uniform standard.” Recalling the struggling history of our party for more than 90 years and maintaining its advanced nature, it has always been our party’s unswerving pursuit of goals. Historical experience in this respect provides important inspiration for our party in coping with various tests under the new situation, overcoming various dangers, enhancing self-purification, self-improvement, self-renovation and self-improvement.
