Peterson's interpretation of housework is deeply scriptural. Keeping House is organized around what Peterson identifies as three crucial imperatives in the Bible—the injunctions to feed the hungry, clothe the naked, and shelter the homeless. Those three activities are at the heart of Jesus' words to the disciples in Matthew 25, and they are at the heart of housekeeping. In Peterson's hands, rather mundane tasks like cooking, washing clothes, and changing the sheets become crucial, transformative acts of love. Insofar as housework is creative, incarnational, physical, and sacramental, exposing the ways the material and the spiritual come together to remind us that "the provision of home is a central aspect of God's creative and redemptive activity," housework allows us to participate in life with the God who called the very dust mites into being.
Cleaning per se doesn't get much attention—Peterson admits that she has never loved mopping or vacuuming, and she suggests that not everyone need hold to identical standards when it comes to washing baseboards and polishing the wooden coffee table. Noting that the late-19th-century sanitation movement led some churches to reject the common Communion cup, she gently queries the interplay between theological conviction and culturally scripted notions about cleanliness. At the same time, she honors the committed housecleaning of an elderly black woman who once told Peterson that Jesus doesn't live in dirt. "I suspect," writes Peterson, "that this lady's doors are clean enough to eat off of. I suspect further that in her life she has encountered many closed doors, but one open door has been the opportunity to keep a clean house, with all the potential excellence and beauty that involves."
