Mar 5:8 Come out of the man, unclean spirit.

IN Christ's words, the are a interesting contrast referenced in this short line. The spirit is an awareness that is contrasted with the body. There is the regular spirit of a person, and unclean spirits, and the Holy Spirit. In the Gospels, the idea that people can lack spirit (poor in spirit) is one of the first ideas that Christ teaches. In the New Testament, person who who we would call mentally ill is describes as being possessed by an unclean spirit. It is from the Holy Spirit, that is, God's spirit, from which we gain knowledge that we cannot normally get.

Spirit is described as having an existence separate from a body. Unclean spirits can leave a body and return, but when they leave, they still exist outside of the body. They are not gone in the same sense that we think a mental condition is cured through treatment. A dead spirit can even be reborn into a new body (Elijah).

Our spirit is also separate from our mental processes. The spirit might inspire a thought or an action, but it is not the thought itself. Christ describes unclean spirits that are separate from the body as still having thoughts even though they don't have bodies. Though spirits can exist without bodies, a spirit with a body can act in the world. Christ describes people in the afterlife as having bodies as well, but of a different form, like the bodies of angels.

Christ describe his words of being of the spirit. People are born of spirit and baptized by spirit.
