The course of ideological and political theory plays an important role in ideological publicity work. In order to get the respect of the society, it should establish and construct its authority. With Chinese social and cultural development, people begin to question the authority of the course of ideological and political theory, resulting in the weakening tendency of its function, such as the weakening of the authority of theory, the weakening of the authority of course, the weakening of the authority of discipline, and the weakening of the authority of organization. In the new era, the course should focus on the construction of conscious authority, such as moral authority, knowledge authority, value authority and expression authority etc. At the same time, the course should stick to the unity of mandatory authority and conscious authority to make the course play an significant role in ideological publicity and value guidance.
