Gardens in the Wasteland is an ethnographic study of Christian formation within three Swedish church plants working against a backdrop of advanced secularisation. The thesis analyses the formative practices employed by these church plants with the intention of forming persons towards a lived Christian identity. Employing a situated learning theory framework, it traces the formative trajectories and negotiations that emerge from these shared practices, and also examines the articulations of callings and intentions within these church plants. The findings reveal that the establishment of a church plant of-ten stems from a sense of place-oriented calling that encompasses a vision of vibrant Christian life and community. These church plants cultivate formative practices -- aimed at certain teloi -- that guide individuals on their journeys towards a lived Christian identity. Through participation in these practices, individuals align themselves with the church plant's vision of Christian life. This identity formation process is not static but rather involves ongoing negotiations, both on a personal and community level, as individuals grapple with the meaning of Christian identity and faith amidst an increasingly secularised society.
