The German occupation of Norway during the Second World War caused unprecedented problems for the Evangelical Lutheran Church of Norway and other Christian denominations. The subordination of the church to the de facto Nazi state eventually led its bishops and most of its pastors to sever their ties to the government while remaining in their ministries. Churchmen and scholars have explored dimensions of this challenging episode in Norwegian church history, but little has been published about the plight of most of the para-church organizations. This article explores crucial dimensions of the ministry of the Norwegian Christian Student Association. Particular attention is paid to how both its pietistic heritage and tradition of social ministry continued to nurture its members and to how the exigencies of living under an oppressive regime compelled the leadership as well as the members of the organization to shift certain emphases in their proclamation and ministry.
