In a comparative view of the Ethics of the enlightened nations of antiquity, of the Jews and of Jesus, no notice should be taken of the corruptions of reason among the ancients, to wit, the idolatry & superstition of the vulgar, nor of the corruptions of Christianity by the learned among its professors.
Let a just view be taken of the moral principles inculcated by the most esteemed of the sects of ancient philosophy, or of their individuals; particularly Pythagoras, Socrates, Epicurus, Cicero, Epictetus, Seneca, Antoninus.
I. PHILOSOPHERS. 1. Their precepts related chiefly to ourselves, and the government of those passions which, unrestrained, would disturb our tranquillity of mind. In this branch of philosophy they were really great.
2. In developing our duties to others, they were short and defective. They embraced, indeed, the circles of kindred & friends, and inculcated patriotism, or the love of our country in the aggregate, as a primary obligation: toward our neighbors & countrymen they taught justice, but scarcely viewed them as within the circle of benevolence. Still less have they inculcated peace, charity & love to our fellow men, or embraced with benevolence the whole family of mankind.
II. JEWS. 1. Their system was Deism; that is, the belief of one only God. But their ideas of him & of his attributes were degrading & injurious.
2. Their Ethics were not only imperfect, but often irreconcilable with the sound dictates of reason & morality, as they respect intercourse with those around us; & repulsive & anti-social, as respecting other nations. They needed reformation, therefore, in an eminent degree.
III. JESUS. In this state of things among the Jews, Jesus appeared. His parentage was obscure; his condition poor; his education null; his natural endowments great; his life correct and innocent: he was meek, benevolent, patient, firm, disinterested, & of the sublimest eloquence.
The disadvantages under which his doctrines appear are remarkable.
1. Like Socrates & Epictetus, he wrote nothing himself.
2. But he had not, like them, a Xenophon or an Arrian to write for him. On the contrary, all the learned of his country, entrenched in its power and riches, were opposed to him, lest his labors should undermine their advantages; and the committing to writing his life & doctrines fell on the most unlettered & ignorant men; who wrote, too, from memory, & not till long after the transactions had passed.
3. According to the ordinary fate of those who attempt to enlighten and reform mankind, he fell an early victim to the jealousy & combination of the altar and the throne, at about 33. years of age, his reason having not yet attained the maximum of its energy, nor the course of his preaching, which was but of 3. years at most, presented occasions for developing a complete system of morals.
4. Hence the doctrines which he really delivered were defective as a whole, and fragments only of what he did deliver have come to us mutilated, misstated, & often unintelligible.
5. They have been still more disfigured by the corruptions of schismatising followers, who have found an interest in sophisticating & perverting the simple doctrines he taught by engrafting on them the mysticisms of a Grecian sophist, frittering them into subtleties, & obscuring them with jargon, until they have caused good men to reject the whole in disgust, & to view Jesus himself as an impostor.
Notwithstanding these disadvantages, a system of morals is presented to us, which, if filled up in the true style and spirit of the rich fragments he left us, would be the most perfect and sublime that has ever been taught by man.
The question of his being a member of the Godhead, or in direct communication with it, claimed for him by some of his followers, and denied by others, is foreign to the present view, which is merely an estimate of the intrinsic merit of his doctrines.
1. He corrected the Deism of the Jews, confirming them in their belief of one only God, and giving them juster notions of his attributes and government.
2. His moral doctrines, relating to kindred & friends, were more pure & perfect than those of the most correct of the philosophers, and greatly more so than those of the Jews; and they went far beyond both in inculcating universal philanthropy, not only to kindred and friends, to neighbors and countrymen, but to all mankind, gathering all into one family, under the bonds of love, charity, peace, common wants and common aids. A development of this head will evince the peculiar superiority of the system of Jesus over all others.
3. The precepts of philosophy, & of the Hebrew code, laid hold of actions only. He pushed his scrutinies into the heart of man; erected his tribunal in the region of his thoughts, and purified the waters at the fountain head.
4. He taught, emphatically, the doctrines of a future state, which was either doubted, or disbelieved by the Jews; and wielded it with efficacy, as an important incentive, supplementary to the other motives to moral conduct.
