Jefferson was raised in the Anglican Church, but his religious views evolved significantly as he was exposed to Enlightenment ideas. He began to question traditional doctrines and embraced a more rational and deistic perspective.

Jefferson was deeply influenced by Enlightenment philosophers such as John Locke and Voltaire, who emphasized reason, natural law, and individual liberty. He adopted deistic principles, believing in a creator God who established natural laws but did not intervene directly in human affairs. Jefferson rejected the divinity of Jesus and the doctrine of the Trinity.

Jefferson was a strong advocate for religious freedom and separation of church and state. He authored the Virginia Statute for Religious Freedom, which disestablished the Anglican Church in Virginia and guaranteed religious liberty for all citizens. This statute became a model for religious freedom in the United States.

Jefferson created 'The Life and Morals of Jesus of Nazareth,' also known as the 'Jefferson Bible,' by excerpting passages from the Gospels that he considered to be the authentic teachings of Jesus. He removed supernatural elements and miracles, focusing on Jesus's moral and ethical teachings. This project reflected his rationalist approach to religion and his belief in the importance of morality.

Jefferson was often cautious about publicly expressing his religious views, as he knew they were controversial and could be used against him politically. He preferred to keep his personal beliefs private, but his actions and writings clearly demonstrate his commitment to religious freedom and his rejection of traditional religious dogma.
