Explanation
This comic plays on the concept of communion wafers -- the thin, unleavened bread used in Christian Eucharist ceremonies, which Catholics believe become the literal body of Christ through transubstantiation.
A woman is reading a book and says: "I dislike the blasphemy, but I LOVE the idea of using cardamom." The joke is that she's reading a cookbook or recipe book that treats communion wafers as a culinary item to be improved with spices like cardamom, rather than as a sacred religious object. She's conflicted because the book is blasphemous (treating the body of Christ as a baking project to be optimized for flavor), yet she can't help but appreciate the recipe suggestions.
The caption below reads: 'There should be a book of wafer recipes called "How to Serve God."' This is a double-layered reference. First, it plays on the classic Twilight Zone episode "To Serve Man," where the title of an alien book turns out to be a cookbook rather than a guide to helping humanity. Similarly, "How to Serve God" sounds like a devotional guide about religious service, but in this context it would be a cookbook about how to serve (prepare and present) God -- i.e., the communion wafer that is supposedly God's body. The joke combines religious satire with culinary humor, poking fun at the idea that if the wafer really is the body of Christ, someone might want to make it taste better.
