The Joke
A priest is performing the Eucharist, the Christian sacrament in which bread (a communion wafer) is consecrated and declared to be the body of Christ. As the priest holds up the wafer and says "This is God's body," Jesus appears behind him in glowing divine radiance, seemingly confirming the transubstantiation. However, the priest then notices that two wafers have gotten stuck together and tries to peel them apart, saying "Oh, one sec, hold on. They got two of these things stuck together."
Jesus immediately recoils in horror, clutching himself in pain, as if the priest is literally tearing his body apart. The child receiving communion watches the whole scene with growing alarm. The comic takes the Catholic doctrine of transubstantiation -- that the bread literally becomes the body of Christ -- to its absurd logical conclusion: if the wafer truly is God's body, then mundane physical actions performed on it (like separating two stuck-together wafers) would cause God real physical distress.
The Humor
The humor comes from the collision between the sacred and the mundane. Transubstantiation is one of the most profound theological claims in Christianity, yet communion wafers are flimsy mass-produced discs that routinely stick together. By having Jesus actually present and reacting in pain to a completely routine wafer-handling issue, the comic highlights the comedic tension between the metaphysical grandeur of the doctrine and the unglamorous physical reality of the ritual. The child's bewildered expression in the final panel adds an extra layer, as he witnesses something that would be deeply traumatizing if the theology were literally true.
