在革命斗争中，党弘扬坚持真理、坚守理想，践行初心、担当使命，不怕牺牲、英勇斗争，对党忠诚、不负人民的伟大建党精神，实施和推进党的建设伟大工程，提出着重从思想上建党的原则，坚持民主集中制，坚持理论联系实际、密切联系群众、批评和自我批评三大优良作风，形成统一战线、武装斗争、党的建设三大法宝，努力建设全国范围的、广大群众性的、思想上政治上组织上完全巩固的马克思主义政党。党从一九四二年开始在全党进行整风，这场马克思主义思想教育运动收到巨大成效。党制定《关于若干历史问题的决议》，使全党对中国革命基本问题的认识达到一致。党的七大为建立新民主主义的新中国制定了正确路线方针政策，使全党在思想上政治上组织上达到空前统一和团结。

In the course of the revolutionary struggle, the Party carried forward its great founding spirit comprised of the following principles: upholding truth and ideals, staying true to its original aspiration and founding mission, fighting bravely without fear of sacrifice, and remaining loyal to the Party and faithful to the people. The Party initiated and advanced the great project of Party building, introduced the principle of focusing on strengthening the Party in ideological terms, and upheld democratic centralism. It stuck to the three fine styles of conduct, namely combining theory with practice, maintaining close ties with the people, and conducting criticism and self-criticism; it developed the three important tools of the united front, armed struggle, and Party building, as it strived to build a national Marxist party of the people, which was fully consolidated in ideological, political, and organizational terms. The rectification movement—a Party-wide Marxist ideological education movement—was launched in 1942 and yielded tremendous results. The Party formulated the Resolution on Certain Questions in the History of Our Party, which helped the entire Party reach a common understanding of the basic questions regarding the Chinese revolution. At the Seventh National Congress, the correct line, principles, and policies were formulated for building a new-democratic China, and as a result the Party became united as never before in ideological, political, and organizational terms.
