In his letters, Thomas Jefferson reflects on the numerous divisions within religions, particularly Christianity, highlighting the chaos and discord stemming from these sects. He points out the tendency of followers to engage in disputes, often leading to extreme actions like persecution and violence over abstract concepts that none truly grasp. Jefferson questions the wisdom of immersing oneself in such turmoil.

This criticism of religious divisions suggests a belief that humanity's attempts to understand profound spiritual truths can lead to unnecessary conflict. Jefferson's observations underline the irrationality of allowing fanaticism and dogma to overshadow reason, advocating for a more unified and understanding approach to spirituality.
