"It was in the mid-eighteenth century, when Moravians questioned the gender of the Trinity, attributed maternal characteristics to Jesus, and celebrated a sensual, mystical personal relationship with their Savior, that Moravian iconography began assigning erotic qualities to the side wound of Christ itself. This included inscribing sensual, colored expressions about Christ and the side wound on hundreds of small cards, many of which contained striking water colors depicting the side wound [...] and/or showing daily activities – eating, sleeping, going for a walk, etc. – inside the wound." -- from Jesus Is Female: The Moravian Challenge in the German Communities of British North America, Aaron Fogleman
"Deep Inside! Deep inside! Deep inside the little side!"
