Chapter 4 treats the Cappadocians’ hagiographic biographies in conjunction with their polemic against non-Trinitarian theologians.The chapter begins by outlining the background and teachings of Eunomius of Cyzicus (c. 335–c. 395), a longtime heterousian rival to the Cappadocians. The chapter analyzes the narratives about fourth-century Nicene bishop Athanasius of Alexandria (c. 298–372), Basil, and Macrina as hagiographies designed in part to contrast true (pro-Nicene) doctrine against the false philosophy of non-Trinitarians.These saints’ ascetic feats are recounted as spiritual ordeals fashioned as classical contests: in Athanasius, suffering multiple exiles because of standing up to false (heterousian) teachers; in Basil, countering threats to the Nicene faith by imperial officials; and in Macrina, enduring disease and death with unwavering resolve.In each case,Nyssen or Nazianzen emphasize that character is formed out of struggle; and that voice and speech (as a metaphor for doctrine) have been purified and validated in pro-Nicene theologians, but are corrupted and disingenuous in the untested charlatans they oppose.
