保持党的纯洁性是马克思主义政党的一贯追求和优良传统;应对“四大考验”和化解“四大危险’,全面提高中国共产党的执政能力,迫切需要增强党的纯洁性;把中国共产党建设成中国特色社会主义事业的坚强领导核心,必须着力以改革创新精神增强党的纯洁性。 Maintaining the purity of the party is the consistent pursuit and fine tradition of the Marxist political parties; we must deal with the ”four major tests“ and the ”four dangers“ of resolving the ”four major dangers" of the party so as to raise the party’s ability to govern in an all-round way and urgently enhance the purity of the party. As the strong leadership core of building the cause of socialism with Chinese characteristics, the Chinese Communist Party must strive to enhance the purity of the party with the spirit of reform and innovation.
