Despite frequent claims that religion serves as a motivator of political behavior in Muslim-majority contexts, empirical evidence of political messaging in sacred spaces is scant. Building on earlier studies on political messaging in both churches and mosques, we examine the presence and nature of political messages across Muslim and Christian religious contexts in a typical Indonesian city, Yogyakarta. Through an analysis of 71 sermons that took place in mosques and churches prior to elections in 2017 and 2019, we analyze the frequency, style, tone, and consistency of political content. We find that political messages within individual houses of worship were often inconsistent from week to week, reducing their potential as a mobilizing force for political action. We also find that houses of worship frequently sought to present themselves as politically neutral spaces in an electoral context in which religious themes are politicized.
