Time in Eusebius’s Ecclesiastical History

Eusebius’s Ecclesiastical History, a seminal late-antique historical narrative, features three periodizations of the church’s past. First, a soteriological periodization divides God’s relationship with humanity at Christ’s Incarnation, an event that Eusebius marks in Book 1 with detailed commentary on the gospels rather than narrative. Second, an ecclesiastical periodization divides pristine, heroic apostolic times from post-apostolic times. The divide between apostolic times and the post-apostolic periods is illustrated through a comparison of History 2.13–17, about Simon Magus, Peter, and Mark, and 6.12, on Serapion of Antioch. And third, an epistemological periodization distinguished earlier times from Eusebius’s lifetime, the latter marked by frequent references to “our time.” Eusebius changed numerous narrative features with his changes of period, including alternating between commentary, diachronic, and synchronic format for different time periods; changing protagonists’ fallibility, individuality, composition of texts, and citation of scripture; and providing notices of episcopal successions and quotation of sources. Moreover, Eusebius’s History changed periods not with the sharp breaks of many modern histories but with gradual transitions. He also underscored key continuities, including God’s intervention in human events and alternation between persecuting and protecting rulers—a continuity within which, contrary to scholarly assumptions, the History never inaugurates a new era with the emergence of Constantine. The case study of Eusebius’s periodization suggests an important limitation of the analytic usefulness of periodizations such as “Late Antiquity” for organizing intellectual history.
