Abstract
The Christian doctrine of Original Sin predicts that every human being deviates
from the moral law universally and without exception. This paper tests that
prediction against the published behavioral data. Using peer-reviewed research
on lying, lustful ideation, anger, envy, dishonesty, and gossip, we establish a
conservative floor estimate of 4.33 discrete sins per person per day and construct
the empirical distribution of daily sin rates across the population. We then
calculate the probability that any human being in the history of the species has
achieved a lifetime sin rate of zero. The result is conclusive. The probability is on
the order of 10⁻⁸⁴·¹⁴⁵, which means that a sinless human life is a 623-sigma event
across a total historical population of approximately 112 billion individuals. The
Augustinian doctrine is confirmed with 124.5x the certainty of the existence of the
Higgs boson: the distribution of human sinfulness makes a naturally sinless
human an absolute mathematical impossibility. Pelagius is refuted not by
theology but by the left tail of the sin distribution. The one historical exception,
Jesus of Nazareth, constitutes a statistical anomaly so extreme that it requires an
explanation outside the mathematical distribution.
