In this article, I analyze the dynamics of Protestants’ ambivalence about their own institutional existence in the context of inter-denominational fighting between Lutheran and Catholic missions in colonial New Guinea. I argue that denominational conflict became a crucial part of the Lutheran missiological method. In particular, it gave them the chance to embrace their Lutheran infrastructure by comparing what they thought of as its life-giving capacities to the dead or false forms of Catholic missionization. Ethnographically, I focus on a moment in the 1930s when two Catholic priests were killed by local people, as well as the ensuing Lutheran response. The priests were killed, according to the Lutherans, because they did not have a spirit-filled infrastructure. The institutional life of the denomination is recognized and yet mitigated through a process of animation, a way of making the most mundane infrastructure the stuff of life-giving force.
