The Christian Conversation

This canon law emphasizes the unity and orthodoxy of the Church by deposing and restricting those who have separated from the synod or embraced heretical doctrines, particularly Nestorius and Celestius.

It clarifies the penalties for bishops, clergy, and laypeople who depart from the established faith, including deposition, degradation, excommunication, and anathematisation.

Additionally, it defends ecclesiastical rights, especially regarding ordinations and jurisdiction, ensuring adherence to ancient canons and resisting unlawful external interference.
