It’s often asserted that at a general level, humans consist of spirit, soul, and body. Interestingly, there is only one passage in the entire Biblical canon that lists the three side by side (1 Thess. 5:23). Even then, that passage has nothing to do with teaching human anthropology. Rather, the Scriptural anthropology teaches humans on the most general level consist of spirit and flesh. These two parts are directly compared, contrasted, and juxtaposed on in dozens of passages – as opposed to just one reference pulled out of context. (Yes, I know that I am going against the orthodoxy here – and I am quite comfortable doing it. Run your own keyword search on the Bible and see what you come up with).
It’s also often asserted that soul is “mind + will + emotions”. Interestingly, this equation originates from Hellenistic theories of the soul, directly traceable to pre-platonic / Pythagorean and early platonic theories of the soul. See Plato’s “Phaedo” (a.k.a. “On the Soul”) and “The Republic” to see where system of thought originated from. Plato’s theory of the soul presented in “The Republic” is:
“Soul = reason (mind) + appetites (emotions) + spirit (will)”.
