Biblical Canon

Churches of Christ affirm the 66-book Protestant biblical canon as the complete and sufficient Word of God. 'Scripture alone' (sola scriptura in practice) is the foundational Restoration principle: all doctrine, worship, and church order must be authorized by Scripture, either explicitly or by approved example and necessary inference.

The Apocrypha and any extracanonical writings are not regarded as Scripture. No human creed, confession, or tradition carries binding authority alongside Scripture. This commitment to the sufficiency of the biblical canon — the 'silence of Scripture' as a prohibition, not merely a permission — is a hallmark of the Churches of Christ hermeneutic.
