This paper documents the strategic use of religious rhetoric by the Republican Party (GOP), particularly in areas characterized by high income inequality. The central hypothesis is that in such areas, it is more challenging for the GOP to win elections solely by advocating for low tax rates. However, the GOP may overcome resistance to low taxes by bundling them with religious rhetoric. Utilizing extensive text data from political speeches in the U.S. Congress, I first demonstrate an increasing trend in the GOP's use of religious rhetoric since the 1990s, which coincides with the widening ideological gap between the GOP and the Democratic Party. By linking the use of religious rhetoric to legislators' ideologies, I find a significant and growing correlation between religious rhetoric and conservative ideology after the 1990s, particularly in states with higher economic inequality. To address potential endogeneity, I use contributions from economically oriented corporate donors as an instrumental variable (IV). Additionally, by aligning the dates of rhetoric with roll call voting records and controlling for legislator-by-year fixed effects, I find that within individual legislators, in months when a legislator votes more conservatively on controversial economic bills, they tend to invoke the word 'God' more frequently in the same month.
