The synod of 922 in Koblenz brought together eight bishops and numerous abbots to address pressing concerns within the Church. Key decisions included prohibitions on incestuous marriages, restrictions on baptism and confirmation, and regulations regarding the management of church properties. The synod emphasized the authority of bishops in ecclesiastical matters and mandated obedience from monks. It also addressed the sale of Christian individuals, the conduct of priests during Mass, and the handling of church disputes. The overarching goal was to uphold the sanctity of the Church and ensure proper governance.
