He continued his letter to Dr. Benjamin Rush, April 21, 1803, stating of Jesus:
"His system of morals ... if filled up in the style and spirit of the rich fragments He left us, would be the most perfect and sublime that has ever been taught by man ...
1. He corrected the Deism of the Jews, confirming them in their belief of one only God, and giving them juster notions of His attributes and government.
2. His moral doctrines ... were more pure and perfect than those of the most correct of the philosophers ... gathering all into one family under the bonds of love, charity, peace, common wants and common aids. A development of this head will evince the peculiar superiority of the system of Jesus over all others.
3. The precepts of philosophy, and of the Hebrew code, laid hold of actions only. He pushed his scrutinies into the heart of man; erected his tribunal in the region of his thoughts, and purified the waters at the fountain head.
4. He taught, emphatically, the doctrines of a future state ... and wielded it with efficacy as an important incentive, supplementary to the other motives to moral conduct."
