There has been a change in the ecclesiology of the well-known Pentecostal pastor and author Peter Halldorf. His ecclesiology was first centered on the individual Christian and he appears to have regarded the church as a group of praying individuals. This ecclesiology could perhaps be regarded to be in line with the ecclesiology of the Swedish Pentecostal movement, the starting point of Halldorf’s ecclesiological processing. Halldorf’s later ecclesiology has taken a controversial turn and is influenced by the Orthodox Church and the Ecumenical Movement. The Pentecostal movement in Sweden has in recent decades undergone major changes which have led to an unclear self-understanding. In spite of the fact that Halldorf is very influential as a pastor and writer, his alternative ecclesiology has not been received as a serious alternative within the Pentecostal movement. In this article I discuss trajectories in Halldorf’s ecclesiology in relation to the ecclesiology of John Howard Yoder. My aim is to provide a Free Church evaluation of Halldorf’s trajectories and my claim is that his development does not necessarily stand in disagreement with the Swedish Pentecostal movement, if one considers the movement’s Baptistic roots. It is therefore possible that Halldorf’s trajectory is a path to follow for the Swedish Pentecostal movement, a movement searching for an identity. It is at the same time possible that the Free Church ecclesiology of Yoder may deepen Halldorf’s own ecclesiology.
