"Redaction critics are rarely conscious of the consequences of their conclusions for the historical-critical evolutionary theory. . . . Nevertheless, the evolutionary theory has collapsed because redaction criticism has pulled the plug on its source of power. Whereas the theory saw the power of literary formation in a romantic symbiosis of tradition and environment, redaction criticism has relocated this power in authors on the one hand and in genres on the other, with genres now construed as cultural media of communication."
