There is a growing realisation across mainstream churches that age-segregated models of connecting with children, young people and families are not working. Drawing on their extensive experience, Suzi Farrant and Darren Philip set out a vision for bringing the generations back together to become the intergenerational church we are designed to be. In conversation with the writings of Dietrich Bonhoeffer, they develop a theological rationale for intentional intergenerational relationships of mutuality lived out within the core activities of the church. Through an exploration of the Christian practices of humility, hospitality, participation, discipleship, joy, worship, discernment and testimony, they call the church to re-discover its DNA as an all-age community of transformation.
