This work, also known as the Canon of King Louis, is a significant ecclesiastical document from 852 that was the result of a synod convened in Mainz under King Louis's command. It emphasizes the importance of unity and peace among Christian leaders, particularly bishops and nobles, as essential for governing the faithful. The document asserts the authority of bishops in ecclesiastical matters and mandates obedience from laypeople. Additionally, it outlines the proper collection and allocation of tithes to ensure the support of the Church and the poor, while also addressing the consequences for those who fail to fulfill their obligations regarding tithes.
