Before 1779, Rush's religious views were influenced by what he described as "Fletcher's controversy with the Calvinists in favor of the Universality of the atonement." After hearing Elhanan Winchester preach, Rush indicated that this theology "embraced and reconciled my ancient calvinistical, and my newly adopted (Arminian) principles. From that time on I have never doubted upon the subject of the salvation of all men." To simplify, both believed in punishment after death for the wicked. His wife, Julia Rush, thought her husband like Martin Luther for his ardent passions, fearless attacks on old prejudices, and quick tongue against perceived enemies.
