But he was pardoned by Julian the Apostate and led the movement to restore the Nicene Creed—and thus orthodoxy—to the empire (see issue 51: Heresy in the Early Church and issue 72: How We Got Our History).
December 16, 1714: Revivalist and evangelist George Whitefield, the best-known figure of the American Great Awakening, is born in Gloucester, England (see issue 38: George Whitefield).
