In January 2024, over 100 Mennonites were arrested in the U.S. capitol building for an act of civil disobedience: protesting by singing hymns. They were part of Mennonite Action, a movement of thousands that uses singing as a central strategy in its call for a permanent ceasefire in Gaza. This workshop will explore how these musical performances function both as protest and as something beyond the registers of politics, religious doctrine, and lexical experience. The presenters, members of Mennonite communities and participants in Mennonite Action events, will explore how heritage and identity work as affective political forces in ways that transcend symbolic meaning. We follow scholars who have written about the politics of pleasure, mobilization of traditions, and polyvalence in musical protest movements (Garofalo, Allen, and Snyder 2019; Taussig 2019; Abe 2018), as well as affective and embodied registers of political action (Cvetkovitch 2003; Shank 2014). We further argue that Mennonites’ use of hymns in these protests evokes a religious affiliation in a way that flips the common trope of “spiritual but not religious” to “religious but not spiritual.” Through singing, Mennonite protestors mobilize a peace church heritage in the form of affective intensity while not necessarily striving to create a spiritual experience. By sharing personal accounts, footage from Mennonite Action events, and stories behind songs that have become prominent in the movement, we invite participants to observe and discuss how these hymns enact political action through and beyond symbolic, embodied, and affective modes of meaning-making.
