Christian theologians differ on how many components make up the human being.
- One part (Monism) – the view that humans are not composed of various components (i.e. body, soul), but rather as a radical unity.
- Two parts (Dichotomism) - the belief that humans are comprised of a material component (body) and a nonmaterial component (soul, or spirit).
- Three parts (Trichotomism) – holds that humans are comprised of three different elements: body, soul, spirit.
