This criticism thesis responds to the absence of post-secular art critical discourse that would set the foundation for a critical discussion about the proliferation of imagery that desecrates Christian symbols on image-based social media by undertaking a case study of the Instagram celebrity artist Naro Pinosa, who uses the medium of digital photo-montaging to produce iconographically-defaced collages that reference Christian imagery. A close reading of eight key images by Pinosa offers a post-secular interpretation of these works. The author draws on Stuart Hall's encoding/decoding model to take up the position of a decoder whose beliefs and values place them in a critical relation to the dominant code of Instagram as a secular social media platform. Through this positionality, the author argues for a reading against the grain of what appears to be anti-Christian imagery.
