It is impossible to assign more than an approximate date to the origin of these documents, but they can hardly be earlier than the monarchy, which is clearly alluded to in Genesis xxxvi. 31. Such incidental statements as that the Canaanite was _then_ in the land, xii. 6, xiii, 7, imply that by the author's time the situation had changed; and, as their subjection was not attained till the time of Solomon (1 Kings ix. 21) the documents can hardly be earlier than that. The sanctuaries glorified in the Pentateuch are the very sanctuaries at which a sumptuous but misguided worship was practised as late as the eighth century, in the days of Amos and Hosea (cf. Amos iv. 4; Hosea xii. II); but, generally speaking, the conception of God found in the prophetic history, though as robust and intense as that of the early prophets, is more primitive. It is not afraid of anthropomorphisms (Gen. iii. 8; Exod. iv. 24), and theophanies, and it has not very clearly grasped the idea that God is spirit. On these grounds alone it would not be unfair to place the prophetic documents somewhere between Solomon and Amos. J probably belongs to the ninth century, and E, which, as we saw reason to believe, was later, to the eighth. P takes us into a totally different world. The witchery of the prophetic documents has disappeared; poetry has given place to legislation, theophany to ritual, religion to theology. From the late historical books, such as Ezra-Nehemiah, we learn that legalism dominated post-exilic religion to an extent out of all proportion to what can be proved, or what is probable, for pre-exilic times; and it would be natural to suppose that another writing, such as P, dominated by precisely the same spirit, is a product of the same time. This supposition becomes a practical certainty in the light of two or three facts. Firstly, in not a few respects P is at variance with the legislative programme drawn up by the exilic prophet Ezekiel (xl.-xlviii.). Now if P had been in existence, such a programme would have been unnecessary, and, in any case, Ezekiel would hardly have ventured to contradict a code which enjoyed so venerable a sanction and bore the honoured name of Moses. It is easier to suppose that Ezekiel's programme is a tentative sketch, which was modified and improved upon by the authors of P. Again there was every inducement during and immediately after the exile to formulate definitely the ritual practice of pre-exilic times, and to modify it in the direction of existing or future needs. So long as the temple stood, custom could be trusted to take care of the ritual tradition, but the violent breach with their country and their past would impose upon the exiles the necessity of securing those traditions in permanent and accessible form. P is therefore referred almost unanimously by scholars to the exilic and early post-exilic age, and may be roughly put about 500 B.C.
