Thomas Morgan _(The Moral Philosopher, a Dialogue between the Christian Deist, Philalethes, and the Christian Jew, Theophanes, 1737 seq_.) stands on the same ground as his predecessors, by holding that the moral truth of things is the criterion of the divinity of a doctrine, that the Christian religion is merely a restoration of natural religion, and that the apostles were not infallible. Peculiar to him are the application of the first of these principles to the Mosaic law, with the conclusion that this was not a revelation; the complete separation of the New Testament from the Old (the Church of Christ and the expected kingdom of the Jewish Messiah are as opposed to each other as heaven and earth); and the endeavor to give a more exact explanation of the origin of superstition, the pre-Christian manifestations of which he traces back to the fall of the angels, and those since Christ to the intermixture of Jewish elements. He seeks to solve his problem by a detailed critique of Israelitish history, which is lacking in sympathy but not in spirit, and in which, introducing modern relations into the earliest times, he explains the Old Testament miracles in part as myths, in part as natural phenomena, and deprives the heroes of the Jews of their moral renown. The Jewish historians are ranked among the poets; the God of Israel is reduced to a subordinate, local tutelary divinity; the moral law of Moses is characterized as a civil code limited to external conduct, to national and mundane affairs, with merely temporal sanctions, and the ceremonial law as an act of worldly statecraft; David is declared a gifted poet, musician, hypocrite, and coward; the prophets are made professors of theology and moral philosophy; and Paul is praised as the greatest freethinker of his time, who defended reason against authority and rejected the Jewish ritual law as indifferent. Whatever is spurious in Christianity is a remnant of Judaism, all its mysteries are misunderstood and falsely (_i.e._ literally) applied allegories. Out of regard for Jewish prejudices Christ's death was figuratively described as sacrificial, as in earlier times Moses had been forced to yield to the Egyptian superstitions of his people. Morgan looks for the final victory of the rational morality of the pure, Pauline, or deistic Christianity over the Jewish Christianity of orthodoxy. Among the works of his opponents the following deserve mention: William Warburton's _Divine Legation of Moses, and_ Samuel Chandler's _Vindication of the History of the Old Testament_.
