A “public minister” is he that by the sovereign, whether a monarch or an assembly, is employed in any affairs with authority to represent in that employment the person of the commonwealth. And whereas every man, or assembly that hath sovereignty, representeth two persons, or, as the more common phrase is, has two capacities, one natural and another politic; as a monarch hath the person not only of the commonwealth, but also of a man, and a sovereign assembly hath the person not only of the commonwealth, but also of the assembly: they that be servants to them in their natural capacity are not public ministers; but those only that serve them in the administration of the public business. And therefore neither ushers, nor sergeants, nor other officers that wait on the assembly for no other purpose but for the commodity of the men assembled in an aristocracy, or democracy; nor stewards, chamberlains, cofferers, or any other officers of the household of a monarch, are public ministers in a monarchy.
