The people of Israel had a supernatural vocation, and they received their law, embracing their religious and civil constitution and their ritual directly from God at the hand of Moses, and various individuals from time to time appear to have been specially called to be their judges, rulers, or kings. Saul was so called, and so was David. David and his line appear, also, to have been called not only to supplant Saul and his line, but to have been supernaturally invested with the kingdom forever; but it does not appear that the royal power with which David and his line were invested was inamissible. They lost it in the Babylonish captivity, and never afterwards recovered it. The Asmonean princes were of another line, and when our Lord came the sceptre was in the hands of Herod, an Idumean Or Edomite. The promise made, to David and his house is generally held by Christian commentators to have received its fulfilment in the everlasting spiritual royalty of the Messiah, sprung through Mary from David's line.
The Christian Church is supernaturally constituted and supernaturally governed, but the persons selected to exercise powers supernaturally defined, from the Sovereign Pontiff down to the humblest parish priest are selected and inducted into office through human agency. The Gentiles very generally claimed to have received their laws from the gods, but it does not appear, save in exceptional cases, that they claimed that their princes were designated and held their powers by the direct and express appointment of the god. Save in the case of the Jews, and that of the Church, there is no evidence that any particular government exists or ever has existed by direct or express appointment, or otherwise than by the action of the Creator through second causes, or what is called his ordinary providence. Except David and his line, there is no evidence of the express grant by the Divine Sovereign to any individual or family, class or caste of the government of any nation or country. Even those Christian princes who professed to reign "by the grace of God," never claimed that they received their principalities from God otherwise than through his ordinary providence, and meant by it little more than an acknowledgment of their dependence on him, their obligation to use their power according to his law and their accountability to him for the use they make of it.
