Why does Jefferson italicize the word Christian?

Jefferson italicizes the Word "Christian" to emphasize its significance and to highlight the distinction between true Christian values and the institutionalized practices of religion. By doing so, he may be critiquing how religion is often used for political purposes or to justify actions contrary to the moral teachings of Christianity. This emphasis reflects his belief in a more rational and ethical interpretation of faith, aligning with his Enlightenment ideals.
