Although John relies on narrative and on `radical rhetoric' to effect persuasion, he
also develops appeals to rational argumentation ( logos), particularly
within the seven oracles, using basic strategies known from classical rhetorical
handbooks and progymnastic exercises. He supports his conclusions and exhortations
with arguments from analogy, from the consequences, from the contrary, from
historical example and from the revelation of contradictions. He employs topics of
courage, the just, the feasible, the (in)expedient and relative expediency in
framing enthymemes. John's argumentation, however, requires previous acceptance of
certain premises derived from Christian `cultural knowledge', for example, that
Christ will come again in judgment, both in interim and ultimate interventions, that
Christ makes his intentions known through prophetic speech, and that Christ's story
provides a paradigm for the disciples to follow per aspera ad astra.
Rational argumentation indeed tempers the authoritarian dimension, but these appeals
to reason will largely only work within Christian culture and would likely be
dismissed outside of early Christian congregations.
