For Christians and the Church, there is the challenge of being "in the world but not of the world". We are called to live in creative tension between being modelers of the faith who keep separate and do not conform to the world, and being infiltrators of the faith who learn to feel at home in the world. Guest speaker and history professor Dr. Perry Bush uses examples from Mennonite history to help us reflect on what it means for us to be faithful followers of Christ today.
