/Confession/Section 50: It is lawful for a Christian to be a magistrate or civil officer; and also it is lawful to take an oath, so it be in truth, and in judgment, and in righteousness, for confirmation of truth, and ending of all strife; and that by wrath and vain oaths the Lord is provoked and this land mourns.
