In 1997, 25 year-old Krista Hunt-Ausland tragically died in a bus accident while volunteering in Bolivia. In her memory, Krista's family founded the Krista Foundation for Global Citizenship supporting Christian young adults engaged in full-time volunteer work during and after their years of service. In 2019, the Foundation has grown to hundreds of members, forming a diverse, disbursed, intergenerational, and interfaith community that incorporates music and arts into its worship, events, and publications. Beginning in 2018, the staff and board sought to formalize a pedagogical approach to expressive and worship arts. The author, an ethnomusicologist and Krista Colleague, autoethnographically chronicles the development of an ethical framework for music and worship in dialogic relationship with a cohort of other colleagues, showing how community ethics impacted the selection of music and art for use in annual conferences and events. This paper approaches expressive arts and worship through the lens of congregational exegesis (Tisdale 1997) and ritual studies (Bell 1992), and draws on research in music, theology, and ethics by Myrick (2018), Moore (2018), Cobussen and Nielsen (2011), Rommen (2007), and Goizueta (1995), offering a case study in arts and worship as practices of relational ethics and accompaniment.
