“Do Not Exasperate Your Children”: Childhood Adversity and the Developing Brain

In the household codes of Colossians and Ephesians, Paul addresses fathers directly, which was unusual in a world where a Roman father held near-total authority over his children. He limits that authority. The reason he gives in Colossians is psychological: “so that they will not lose heart.” Harsh, provoking treatment does not just produce bad behavior. It discourages something deep in the child. Ephesians gives the positive side: discipline and instruction “of the Lord,” shaped by his character.

This addition pairs naturally with the paper’s Bonus section on “Train up a child,” which focuses on what children learn by imitation and repetition. This one looks at the other side: what harm in the home does over time.

The ACE study. In one of the most influential public-health studies of the last thirty years, Felitti and colleagues (1998) surveyed 9,508 adults who had received a standard medical exam at a large health plan. They asked about seven kinds of adverse childhood experiences: psychological, physical, or sexual abuse; violence against the mother; and living with someone who abused substances, was mentally ill or suicidal, or had been imprisoned. More than half reported at least one. The more categories a person reported, the higher his risk for nearly every adult health problem studied, in a graded pattern. Compared with those who reported none, people with four or more categories had 4 to 12 times the risk of alcoholism, drug abuse, depression, and suicide attempts, and higher rates of heart disease, cancer, lung disease, and liver disease.

What adversity does to the developing brain. Teicher, Samson, Anderson, and Ohashi (2016) reviewed the brain research on childhood maltreatment. They describe it as the leading preventable risk factor for mental illness and substance abuse. Maltreatment appears to alter the development of sensory systems, of how brain networks are organized, and of circuits for detecting threat, regulating emotion, and anticipating reward. The authors weigh whether these changes are purely damage or partly adaptations to a dangerous environment. They also stress resilience: many maltreated children do not develop disorders.

What the studies cannot tell us. The ACE study relies on adults’ memories of childhood, and it measures abuse and serious household dysfunction, not ordinary parental mistakes. A father who loses his temper and then apologizes is not doing what the ACE study measured. It would be wrong to frighten good fathers with brain-damage language. The convergence is with Paul’s limit on a father’s power: a home ruled by fear and harshness can leave lasting marks, and the father’s character is a large part of what makes a home safe.

Practice

Living it out

Five practices drawn from this passage. Each says how strong the research behind it is. What the labels mean.

1. 1

   Repair quickly after you blow it

   When you are harsh with a child, go back the same day, name what you did, and ask forgiveness.

   ObedienceObedience. Commended by Scripture (Eph. 4:26, 32; see Section 5 of the paper). Repair after ordinary conflict was not measured in the studies here.
2. 2

   Separate discipline from anger

   Decide on consequences when you are calm, not in the heat of the moment. If you are too angry to discipline fairly, say “We’ll talk about this in an hour,” and do.

   EarlyEarly, by inference from the paper’s research on cooling down before conflict (Section 9) and on arousal-lowering activities (Kjærvik & Bushman, 2024).
3. 3

   Don’t let your own history run your home

   If you grew up with several of the ACE categories, know that this raises risks for you, and that those risks can be addressed. Talk to a counselor, especially if you notice the same patterns in yourself.

   StrongStrong that adverse childhood experiences are linked to adult health risks in a graded way (Felitti et al., 1998).
4. 4

   Be the safe adult for someone else’s child

   Coaches, Sunday school teachers, uncles, and neighbors can be a steady presence for a child from a hard home.

   EarlyThe review notes that many maltreated children are resilient (Teicher et al., 2016). Specific protective relationships were not studied in the sources here.
5. 5

   If a child is in danger, act

   If you know of abuse, report it to the authorities and get help. Protecting a child is not gossip or disloyalty.

   StrongStrong that maltreatment is a leading preventable risk factor for later mental illness and substance abuse (Teicher et al., 2016).
