Scot McKnight delivers a surprising Fourth of July reflection that sidesteps political fireworks to expose a quiet revolution in rural America and the hidden biology of our bodies. While most holiday essays focus on patriotism or policy, McKnight weaves together data on religious decline, tattoo immunology, and conservation efforts to argue that American identity is being rewritten from the ground up—and inside out.
The Unseen Shifts in Rural Faith
McKnight's most arresting claim isn't about the rise of secularism in cities, a trend well-documented by sociologists for decades. Instead, he turns his lens to the countryside, revealing a demographic earthquake that defies traditional political narratives. "The big thing that I take away from this is that the nones are rising among younger generations in basically the same way whether we are talking about big cities or small towns," McKnight writes. This observation upends the assumption that rural America remains a monolith of religious conservatism.
He details how evangelicalism has lost significant ground with each successive generation living in these geographies. Among Boomers, 30% identified as evangelical; for Generation Z, that number has plummeted to 12%. "Remember that evangelicals have dominated these kinds of places for decades now, but according to this data that may not be true going forward," McKnight notes. This framing is crucial because it suggests the cultural and political bedrock of rural America is eroding faster than polling aggregates suggest.
The rise of the young, rural none is not something that I've ever seen written about.
Critics might argue that focusing on a demographic representing just 10% of the total sample overstates its immediate political impact. McKnight himself concedes this limitation, noting that "rural America is obviously not that many people." However, his point remains potent: if these communities are no longer reliably evangelical, the long-term realignment of rural politics could be far more volatile than current election cycles predict. The data suggests a fracture in the coalition that has defined American cultural wars for half a century.
Ink, Immunity, and Permanent Marks
Shifting from sociology to biology, McKnight explores the physical cost of self-expression through tattoos, using the recent health scare of musician MGK as a case study. He explains that tattooing is not merely skin deep; it triggers a permanent immune response where pigment particles enter the lymphatic system. "Introducing tattoo pigment into the skin triggers an immune response, and that ink obviously sticks around – though it doesn't always stay put," McKnight writes.
He highlights how MGK's massive blackwork piece caused his surrounding skin to turn yellow and made him "really sick" because the ink traveled to lymph nodes near his armpits and shoulders. These nodes act as filters for the immune system, trapping foreign substances like bacteria, viruses, and tattoo ink. While there is no definitive proof linking tattoos to cancer in humans, McKnight points out that lab studies and one observational study suggest a 29 percent higher risk of melanoma among tattooed individuals.
The core of his argument here is a cautionary note about the "lifelong battle" our bodies fight against ink particles that are too large for immune cells to remove. As he puts it, "Chronic inflammation has been linked to tissue damage and increased disease risk." This perspective reframes tattoos from simple art to a complex biological negotiation with long-term consequences.
For people with autoimmune conditions or weakened immune systems, tattoos may pose additional concerns.
This section effectively bridges the gap between pop culture and medical science, reminding readers that "growing research highlights important unanswered questions about toxicity, immune effects and long-term health." While some might argue that anecdotal evidence from celebrities shouldn't drive public health anxiety, McKnight balances this by citing rigorous studies rather than fear-mongering. The takeaway is clear: the permanence of a tattoo extends beyond aesthetics into the realm of immunology.
Sacred Texts in Secular Spaces
McKnight also tackles the contentious debate over teaching the Bible in Texas public schools, arguing that the controversy often misses the forest for the trees. He posits that the question shouldn't be whether the Bible belongs in classrooms, but why it is being taught. "If the purpose is to teach students to read rich literary texts to better equip them to understand and appreciate literary and cultural traditions, then teaching key passages from the Bible is an excellent idea," he writes.
He leans heavily on novelist Marilynne Robinson's 2011 essay to support this view, quoting her assertion that "The Bible is the model for and subject of more art and thought than those of us who live within its influence... will ever know." McKnight argues that excluding such texts leaves students ill-equipped to understand Western literature and history. However, he draws a sharp line when the motivation shifts from education to ideology.
"If the motivation for requiring the Bible in public school classrooms is something other than offering a sound education in literature... if it is merely a ham-fisted attempt to advance a Christian nationalist agenda – then Christians seeking to follow the way of Jesus ought to be wary," McKnight warns. This distinction is vital in an era where curriculum battles often serve as proxies for broader culture wars.
The right question isn't whether the Bible should be required, but why it is.
A counterargument worth considering is that even "literary" instruction of religious texts can feel coercive to students from non-Christian backgrounds, regardless of the teacher's intent. McKnight acknowledges this tension by suggesting schools teach a wide array of texts—from the Tao Te Ching to Toni Morrison—to ensure a balanced communal knowledge base. His approach prioritizes educational rigor over theological advocacy, a stance that appeals to both secular and religious educators seeking common ground.
The Scale of Modern Megachurches
Finally, McKnight observes a paradoxical trend: while small-town faith is waning, the largest churches in America are growing at an unprecedented rate. He notes that the top ten churches combined for just over 260,000 members in 2015, a figure that swelled to over 427,000 by 2025. "One huge thing that jumps out to me is that the biggest churches in the United States have gotten a whole lot bigger in the last decade," McKnight writes.
This concentration of attendance suggests a shift toward centralized, media-savvy religious institutions rather than local, community-based congregations. The data shows newcomers like Life.Church and Lakewood Church joining established giants, indicating that scale is becoming a defining feature of American religious life. This trend contrasts sharply with the decline in rural evangelicalism, painting a picture of a fragmented religious landscape where influence is increasingly concentrated in a few massive hubs.
Bottom Line
McKnight's "Fourth of July meanderings" succeed by connecting disparate threads—rural demographics, immunology, and curriculum policy—to reveal a nation in flux. The strongest part of his argument is the data-driven revelation that rural secularism is rising as fast as urban secularism, challenging deep-seated political assumptions. His biggest vulnerability lies in the speculative nature of some health claims regarding tattoos, though he carefully qualifies these with "unanswered questions." Readers should watch for how this rural religious shift reshapes local politics in the next election cycle, as the demographic tectonic plates continue to move beneath our feet.
