Keynote Presentations

Brief Description

“Justice and peace shall kiss” is a poetic picture of big ideas. Justice and peace can feel abstract and unachievable. Yet these visions of God’s Kingdom are something the followers of Jesus, gathered in churches, labor toward by the Spirit and with practical action. Many tools and frameworks exist to bring “justice and peace” out of abstraction and into tangible steps and concrete actions in the name of Jesus. Jenn and Nate Hosler will lead us through tools and strategies to understand and engage the social ecology of our churches and communities. They will draw on their experiences and background in community psychology, institutional development, urban church pastoring, and work for systemic change. Jenn and Nate will utilize an asset-based approach to understanding our congregational contexts. They will root the conversations in a theology of holistic ministry, while inviting participants to explore how their churches can embody and manifest justice and peace.


Jennifer Hosler and Nathan Hosler are pastors of Washington City Church of the Brethren, in Washington, DC, and they each serve as denominational staff within the Church of the Brethren.
