Dr. Welch has a Ph.D. in psychology as well as theology degrees, and has been a counselor for years. His doctoral work was on brain physiology, so Blame it on the Brain is the fruit of 20 years of reflection on the subject.
Welch wonders if the brain "has been given too much credit" (p. 12). Many have held the brain responsible for some bad behavior: "My disease did it!" (p. 13). While the observations of the rapidly expanding field of brain sciences can be very helpful, when interpreted through a biblical lens they can be put in a more modest and helpful perspective. How do these discoveries illustrate biblical truths that can be applied to people's lives? Instead, too often sin problems are mislabeled as solely brain problems, and thus the true cause is left unaddressed (p. 25).
Four very practical principles emerge from this approach to mind-body issues: 1. The brain cannot by itself `make' a person sin (pp.49f.). 2. Each person's abilities (brain strengths and weaknesses) are unique (pp.53f.). 3. Brain problems can expose heart problems (pp.56f.). 4. Sinful hearts can lead to physical illness; upright hearts can contribute to good health (pp.58f.).
In part two of the book these principles are then concisely but thoughtfully applied to a series of examples. First are apparently physical issues: Alzheimer's disease (pp. 67f.) and head injury (pp.85f.). Next are more psychiatric issues: depression (pp.115f.), "A.D.D." (pp. 131f.), homosexuality (pp.151f.), and alcoholism (pp. 183f.).
Welch's treatments of these problems abound with practical, sensitive insight. In the process he clearly defines the deeper issues at stake: what is the soul?; what is the body?; what is sin?
For me, a crucial component of the book is the section on the mind-body relationships, especially pp. 43-48. Welch is careful to distinguish the heart from the body, but without separating them. Drawing upon rich Trinitarian analogies, he is careful to outline a model that seeks not to over-emphasize either the duality or the unity. This understanding enables us to try to distinguish between sin and sickness. As Welch ably define sit: "any behavior that does not conform to biblical commands or any behavior that transgresses biblical prohibitions proceeds form the heart and is sin" (p. 43). Conversely, "any behavior that is more accurately called a weakness proceeds form the body and is sickness or suffering" (p. 44). We are to repent of sin. But things that reflect only our creaturely limitations are not immoral, but proceed from our fallen bodies.
The example Welch uses of hallucinations is illustrative. The Bible does not prohibit them, so we can not admonish someone for experiencing them. We are called to compassion for them. The hallucination may have been caused by a prior sinful choice, and the hallucinatory may respond to them with sin, but the hallucination itself is not sinful. A helpful chart on p. 45 lists out some examples of body problems (broken bones, mental retardation, feelings of depression, hallucinations) and heart (mind) problems (anger, pride, drunkenness). Of course, many problems involve both the body and the heart or mind, and in unequal and obscured proportions. How do we separate out the differences? And why is it helpful to try?
