Westminster Confession of Faith

For the better government, and further edification of the Church, there ought to be such assemblies as are commonly called synods or councils.⁵⁶⁰

As magistrates may lawfully call a synod of ministers, and other fit persons, to consult and advise with, about matters of religion;⁵⁶¹ so, if magistrates be open enemies to the Church, the ministers of Christ of themselves, by virtue of their office, or they, with other fit persons upon delegation from their Churches, may meet together in such assemblies.⁵⁶²

It belongs to synods and councils, ministerially to determine controversies of faith and cases of conscience; to set down rules and directions for the better ordering of the public worship of God, and government of his Church; to receive complaints in cases of maladministration, and authoritatively to determine the same: which decrees and determinations, if consonant to the Word of God, are to be received with reverence and submission; not only for their agreement with the Word, but also for the power whereby they are made, as being an ordinance of God appointed thereunto in His Word.⁵⁶³

All synods or councils, since the Apostles' times, whether general or particular, may err; and many have erred. Therefore they are not to be made the rule of faith, or practice; but to be used as a help in both.⁵⁶⁴

Synods and councils are to handle, or conclude, nothing, but that which is ecclesiastical: and are not to intermeddle with civil affairs which concern the commonwealth; unless by way of humble petition, in cases extraordinary; or by way of advice, for satisfaction of conscience, if they be thereunto required by the civil magistrate.⁵⁶⁵
