It has now been sufficiently argued and demonstrated that kings after Moses were, at the command of God, bound by all laws just as the people were, and that no exemptions from the laws are found in scripture. So it is quite false, and said without authority and reason, that kings ‘could do with impunity what they wanted’ or that ‘they could not be punished by the people’ and accordingly that ‘God has reserved their punishment to his own tribunal’. Let us see whether the gospel advises what the law did not advise, and did not command either. Let us see whether the gospel, that divine proclamation of liberty, sentences us to slavery under kings and tyrants, from whose lawless power the old law, though it also taught some kind of slavery, did free the people of God.
Your first proof you take from the character of Christ - but who does not know that he took on the character not only of a private Citizen but even of a slave so we might be free? Nor is this to be understood merely of internal freedom and not of civil liberty. For how strange are those words which Mary, mother of Christ, uttered in prophecy of his Coming - ‘he has scattered the proud in the thought of their own hearts, he has dragged down rulers from their thrones, he has exalted the humble’ - if his Coming rather strengthened tyrants on the throne and subjected all Christians to their most savage rule. By being born, serving and suffering under tyrants, he has himself obtained all honourable liberty for us. As Christ has not removed from us the ability to endure slavery with calmness if it is necessary, so too he has left us with the ability to aspire honourably to liberty, but has granted the latter in greater measure. Hence Paul, I Cor. 7, decides thus, not only of evangelical but also of civil liberty: ‘Have you been summoned, since you are a slave? Do not heed it, but if you can be made free, enjoy it rather. You have been bought at a price, do not be the slaves of men.’
