Spirit and Soul
Spirit is often used metaphysically to refer to the consciousness or personality. A spirit is a supernatural being, often, but not exclusively, a non-physical entity; such as a ghost, fairy, or angel. The concepts of a person’s spirit and soul, often also overlap, as both are either contrasted with or given ontological priority over the body and both are believed to survive bodily death in some religions, and “spirit” can also have the sense of “ghost“, i.e. a manifestation of the spirit of a deceased person. In English Bibles, “the Spirit” (with a capital “S”), specifically denotes the Holy Spirit.
The soul, in many religious, philosophical, and mythological traditions, is the incorporeal essence of a living being. Soul or psyche (psū́khein, “to breathe”) are the mental abilities of a living being: reason, character, feeling, consciousness, memory, perception, thinking, etc. Depending on the philosophical system, a soul can either be mortal or immortal.
Pneumatology is the study of spiritual beings and phenomena, especially the spiritual aspect of human beings and the interactions between humans and God.
