Book excerpt: Second century apocryphal Christian texts are Christian fiction: they draw on the motifs of contemporary pagan stories of romance, travel and adventure to entertain their readers, but also to explore what it means to be Christian. The Thecla episodein the Apocryphal Acts of Paul recounts the conversion of a young pagan woman, her rejection of marriage, her narrow escapes from martyrdom and the end of her story as an independent, ascetic evangelist. In Thecla's Devotion, J.D. McLarty reads the Thecla episode against a paradigm pagan romance, Callirhoe: for both texts the passions are key to the unfolding of the plot - how are unruly emotions to be managed and controlled? The pagan would answer, 'through reason'. This study uses the portrayal of emotion within character and plot to explore the response of the Thecla episode to this key question for Christian identity formation.
