Generational Sin and Epigenetics

The concept of generational sin, that we inherit sins of our ancestors (based on Exodus 20:5), is popular in some contemporary Christian circles. Recently, the field of epigenetics, which examines the effects of environment on genetic expression, has been used to support this idea. This claim is evaluated by contextually examining relevant biblical passages and the broader theological concept of sin, concluding that there is insufficient biblical evidence to support the concept. Similarly, recent scientific research suggesting epigenetic transgenerational transmission of consequences of adverse experiences, though interesting and informative, does not prove that trauma effects in humans are caused by epigenetic changes. Inherent and experiential factors (nature and nurture) are intertwined and, ultimately, we are each responsible for our own thoughts and actions.
