The Old Testament has always been something of an embarrassment to the Christian church. The book was Scripture and its heroes were to be taken as examples. Nevertheless there was much in their conduct which ran counter to the prevailing Christian ethics. A problem thus arose both in exegesis and in ethics. Were the patriarchs to be justified? Should they be imitated? Marcion evaded the difficulty by simply rejecting the Old Testament, pointing out the complete antithesis, for example, between the precept, “Let not the sun go down upon your wrath,” and the conduct of Joshua, who kept the sun up till his wrath went down. In the main the fathers resolved such difficulties by allegory, but even this key did not suffice. There was no denying that Moses really slew the Egyptian, that the Israelites robbed them, that Abraham lied, that Jacob was polygamous, and that Samson committed suicide, not to mention the deeds which made it appropriate to attribute to David the penitential psalms. Origen, the prince of allegorists, admitted that the incest of Lot and the polygamy of Abraham and Jacob were “mysteries not understood by us.”
