Politics and religion are traditionally connected in large democracies, with many examples in the Global South. Recently in Brazil, a specific Bible verse has been assimilated into political expression and amplified by social media: John 8:32 (“And you shall know the truth, and the truth will set you free”). In this article, we employ thematic analysis of Twitter1 data referencing this verse, collected during the 2022 Brazilian presidential election. The analysis shows how the verse became symbolic shorthand for a bundle of values associated with political and religious righteousness, reinforcing the connections between conservative politics and religion. Strongly associated with the persona of former president Jair Bolsonaro, the verse was deployed by his supporters as a symbolic debunking tool against perceived misinformation but was also used ironically by Bolsonaro’s detractors to criticize the former president. By zooming in on the multifaceted use of this Biblical verse in the online political sphere, this article illuminates the multilayered interconnections between political expression on social media, religion, and misinformation in the context of Brazil.
