Article XXXIX. Of a Christian Man's Oath
As we confess that vain and rash Swearing is forbidden Christian men by our Lord Jesus Christ, and James his Apostle, so we judge, that Christian Religion doth not prohibit, but that a man may swear when the Magistrate requireth, in a cause of faith and charity, so it be done according to the Prophets' teaching, in justice, judgment, and truth.
