None of the prophets puts the point more clearly than Isaiah. After condemning hypocrisy, he commends liberty and charity towards oneself and one's neighbors, and promises as a reward: "Then shall thy light break forth as the morning, and thy health shall spring forth speedily, thy righteousness shall go before thee, and the glory of the Lord shall be thy reward" (chap. lviii. 8). Shortly afterwards he commends the Sabbath, and for a due observance of it promises: "Then shalt thou delight thyself in the Lord, and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord has spoken it." Thus the prophet, for liberty bestowed and charitable works, promises a healthy mind in a healthy body, and the glory of the Lord even after death; whereas, for ceremonial exactitude, he only promises security of rule, prosperity, and temporal happiness.

... It remains to show why and how the ceremonial observances tended to preserve and confirm the Hebrew kingdom; and this I can very briefly do on grounds universally accepted.

The formation of society serves not only for defensive purposes, but is also very useful, and, indeed, absolutely necessary, as rendering possible the division of labor. If men did not render mutual assistance to each other, no one would have either the skill or the time to provide for his own sustenance and preservation: for all men are not equally apt for all work, and no one would be capable of preparing all that he individually stood in need of. Strength and time, I repeat, would fail, if every one had in person to plow, to sow, to reap, to grind corn, to cook, to weave, to stitch and perform the other numerous functions required to keep life going; to say nothing of the arts and sciences which are also entirely necessary to the perfection and blessedness of human nature. We see that peoples living in uncivilized barbarism lead a wretched and almost animal life, and even they would not be able to acquire their few rude necessaries without assisting one another to a certain extent.

Now if men were so constituted by nature that they desired nothing but what is designated by true reason, society would obviously have no need of laws: it would be sufficient to inculcate true moral doctrines; and men would freely, without hesitation, act in accordance with their true interests. But human nature is framed in a different fashion: every one, indeed, seeks his own interest, but does not do so in accordance with the dictates of sound reason, for most men's ideas of desirability and usefulness are guided by their fleshly instincts and emotions, which take no thought beyond the present and the immediate object. Therefore, no society can exist without government, and force, and laws to restrain and repress men's desires and immoderate impulses. Still human nature will not submit to absolute repression. Violent governments, as Seneca says, never last long; the moderate governments endure.

So long as men act simply from fear they act contrary to their inclinations, taking no thought for the advantages or necessity of their actions, but simply endeavoring to escape punishment or loss of life. They must needs rejoice in any evil which befalls their ruler, even if it should involve themselves; and must long for and bring about such evil by every means in their power. Again, men are especially intolerant of serving and being ruled by their equals. Lastly, it is exceedingly difficult to revoke liberties once granted.

From these considerations it follows, firstly, that authority should either be vested in the hands of the whole state in common, so that every one should be bound to serve, and yet not be in subjection to his equals; or else, if power be in the hands of a few, or one man, that one man should be something above average humanity, or should strive to get himself accepted as such. Secondly, laws should in every government be so arranged that people should be kept in bounds by the hope of some greatly desired good, rather than by fear, for then every one will do his duty willingly.

Lastly, as obedience consists in acting at the bidding of external authority, it would have no place in a state where the government is vested in the whole people, and where laws are made by common consent. In such a society the people would remain free, whether the laws were added to or diminished, inasmuch as it would not be done on external authority, but their own free consent. The reverse happens when the sovereign power is vested in one man, for all act at his bidding; and, therefore, unless they had been trained from the first to depend on the words of their ruler, the latter would find it difficult, in case of need, to abrogate liberties once conceded, and impose new laws.

From these universal considerations, let us pass on to the kingdom of the Jews. The Jews when they first came out of Egypt were not bound by any national laws, and were therefore free to ratify any laws they liked, or to make new ones, and were at liberty to set up a government and occupy a territory wherever they chose. However, they were entirely unfit to frame a wise code of laws and to keep the sovereign power vested in the community; they were all uncultivated and sunk in a wretched slavery, therefore the sovereignty was bound to remain vested in the hands of one man who would rule the rest and keep them under constraint, make laws and interpret them. This sovereignty was easily retained by Moses, because he surpassed the rest in virtue and persuaded the people of the fact, proving it by many testimonies (see Exod. chap. xiv., last verse, and chap. xix., verse 9). He then, by the Divine virtue he possessed, made laws and ordained them for the people, taking the greatest care that they should be obeyed willingly and not through fear, being specially induced to adopt this course by the obstinate nature of the Jews, who would not have submitted to be ruled solely by constraint; and also by the imminence of war, for it is always better to inspire soldiers with a thirst for glory than to terrify them with threats; each man will then strive to distinguish himself by valor and courage, instead of merely trying to escape punishment. Moses, therefore, by his virtue and the Divine command, introduced a religion so that the people might do their duty from devotion rather than fear. Further, he bound them over by benefits, and prophesied many advantages in the future; nor were his laws very severe, as any one may see for himself, especially if he remarks the number of circumstances necessary in order to procure the conviction of an accused person.

Lastly, in order that the people which could not govern itself should be entirely dependent on its ruler, he left nothing to the free choice of individuals (who had hitherto been slaves); the people could do nothing but remember the law, and follow the ordinances laid down at the good pleasure of their ruler; they were not allowed to plow, to sow, to reap, nor even to eat; to clothe themselves, to shave, to rejoice, or, in fact, to do anything whatever as they liked, but were bound to follow the directions given in the law; and not only this, but they were obliged to have marks on their doorposts, on their hands, and between their eyes to admonish them to perpetual obedience.

This, then, was the object of the ceremonial law, that men should do nothing of their own free will, but should always act under external authority, and should continually confess by their actions and thoughts that they were not their own masters, but were entirely under the control of others.
