Ephesiology [n. ih·fē·zē·äləʒē]: The Study of the Ephesian Movement Studying the Christian Movement in Ephesus is a community conversation about the most significant church-planting movement in the early church, with 40 percent of the New Testament texts relating to it. What made that city the epicenter of the movement? And how can we replicate sustained movements in a world that feels so different? This is not another methodology or attempt to re-contextualize evangelicalism. Rather, it is a look at the story of how the Holy Spirit still changes lives, cities, and the world.
