At the same time it became a matter of duty to me, if possible, to discriminate the authoritative from the unauthoritative in the Scripture, or at any rate avoid to accept and propagate as true that which is false, even if it be false only as science and not as religion. I unawares,--more perhaps from old habit than from distinct conviction,--started from the assumption that my fixed point of knowledge was to be found in the sensible or scientific, not in the moral. I still retained from my old Calvinistic doctrine a way of proceeding, as if purely moral judgment were my weak side, at least in criticizing the Scripture: so that I preferred never to appeal to direct moral and spiritual considerations, except in the most glaringly necessary cases. Thus, while I could not accept the panegyric on Jael, and on Abraham's intended sacrifice of his son, I did not venture unceremoniously to censure the extirpation of the Canaanites by Joshua: of which I barely said to myself, that it "certainly needed very strong proof" of the divine command to justify it. I still went so far in timidity as to hesitate to reject on internal evidence the account of heroes or giants begotten by angels, who, enticed by the love of women, left heaven for earth. The narrative in Gen. vi. had long appeared to me undoubtedly to bear this sense; and to have been so understood by Jude and Peter (2 Pet. ii.), as, I believe, it also was by the Jews and early Fathers. I did at length set it aside as incredible; not however from moral repugnance to it, (for I feared to trust the soundness of my instinct,) but because I had slid into a new rule of interpretation,--that _I must not obtrude miracles on the Scripture narrative_. The writers tell their story without showing any consciousness that it involves physiological difficulties. To invent a miracle in order to defend this, began to seem to me unwarrantable.
