Recent literature on the political participation of Pentecostal evangelicals in Brazil has drawn attention to the transformations caused by their use of digital media. To broaden this debate, in this article I describe the everyday use of the WhatsApp instant messaging program by prayer groups, shedding light on how disputes engaged by Pentecostal women have re-signified their pastoral careers and formed new evangelical collectivities. With the emergence of other ways of experiencing the intimacy provided by mobile devices, I reflect on religious connections established across images and sounds in WhatsApp groups, in addition to the digital impact on the dynamics of female religious authority and its transnational expansion.
