Josephus begins by confronting the widespread skepticism among the Greeks regarding Jewish history, contrasting the fleeting records of Hellenic civilization with the carefully preserved traditions of ancient nations like the Egyptians, Chaldeans, and Phoenicians. He argues that the Greeks lacked early public records and often wrote histories based merely on conjecture or a desire to entertain, whereas the Jewish nation maintained an unbroken, meticulous lineage of high priests and sacred writings. To substantiate his claims, Josephus produces testimonies from foreign historians, including Manetho, Dius, Menander, and Berosus, demonstrating that external archives frequently corroborate biblical chronology and historical events, such as the construction of Solomon's temple and the Babylonian captivity.
Moving to the second part of his work, Josephus systematically dismantles the malicious calumnies propagated by writers like Apion, Apollonius Molo, and Lysimachus. These detractors fabricated absurd stories, such as the myth that the Jews worshipped an ass's head or practiced ritual human sacrifice of Greek foreigners. Josephus exposes the internal contradictions, ignorance, and malicious intent behind these fabrications, noting that reputable historians like Strabo and Polybius never encountered such bizarre practices during their conquests and inspections of the temple.
In the final sections, Josephus provides a comprehensive exposition and defense of the Mosaic constitution and laws. He explains that Moses established a theocracy, anchoring all civic duties, moral virtues, and daily practices in a profound reverence for God. Unlike the fluctuating laws and contradictory moral standards of Greek city-states, the laws given to the Jews promote justice, temperance, mutual concord, and an unshakeable commitment to truth. Josephus emphasizes that the endurance of these laws through millennia of persecution and dispersion stands as the ultimate proof of their divine origin and enduring excellence.
