The refusal to use fine rhetoric on the part of those who would perhaps have been able to use it—the Cynics in particular—testifies to their aloofness from a society which they criticized. The low style of the early Christian message has been interpreted that way; and there is no doubt that Christians of the second generation, such as Luke and the author of Hebrews, are more “conformed” and acculturated to Hellenism as is, for example, the Apostle Paul. In this sense Paul’s scorn of rhetoric (1 Cor. 1:17, 20; 2:4-5, 13 etc.) could be termed “cynical”. With respect to the paltriness and intellectual mediocrity of many utterances of second-century Christianity, however, it may be asked to what degree rhetorical restraint was based on voluntary discretion. Wasn’t the Christian mission from its very inception dependent upon the use of the available means of communication? In line with Matthew 28:18-20 is the fact that the bishops soon became rhetoricians—or, to put it more exactly, that Christian rhetoricians became bishops.
