Long after you’re born, your mother’s body continues to carry your cells—and you carry hers. The science behind this phenomenon is called fetomaternal microchimerism, and by bringing attention to this reality Dr. Kristin Collier dismantles the modern myth that we are isolated, autonomous, self-made individuals. The significance of relational biology is that you are never alone. On its own, the science is fascinating. But it becomes something far more profound when you consider the theological implications—especially for the Theotokos, the God-bearer who carried the very cells of Christ within her body—and her cells within His.In this conversation, the University of Michigan physician—whose 2022 white coat address famously provoked a walkout—explores how faith and reason work best together, why medicine has become an idol for many, and what it truly means to see human beings as embodied persons rather than machines. Dr. Collier makes a compelling case for a proper view of health as right relationship, the power of story in medicine, and the deep biological and spiritual reality that we are never truly alone.
