“How Does Heaven Come to Speak?”
After the death of emperor Zhenzong, scholar-officials challenged the legitimacy of the Heavenly Text and the cult of the Sacred Ancestor. They argued that because there was no way that Heaven could speak through the proposed revealed text, the Heavenly Text was fabricated. A consensus was reached between Emperor Renzong and officials that Confucian canonical rituals would be the sole orthopraxis of imperial rituals, and the cult of the Sacred Ancestor would be reduced to a private ritual of the royal family. Later, those who advocated increasing the power of the bureaucracy at the expense of the monarch took the lead in deploying the ancient ritual laws as a means to compel compliance by the emperor and also to attack officials of the opposing faction. As “three-year mourning” became a legal obligation for all civil officers, many politically charged allegations were made, which in turn further stimulated the study of the canonical rituals.
