Passages could be multiplied to show that soul and spirit are applied in the Scriptures to the one and self-same immaterial substance of man. The Trichotomist theory is therefore unsatisfactory. The theory of the Dichotomists, who bold that man is composed of only two parts, viz., body and soul or spirit, is Biblical. Here two parts of man, and only two, are mentioned -body and soul. It is true, however, that there is a distinction of relations between these in their application to the immaterial part of man's nature.
Soul always carries with it a reference, past, present, or future, to the body.
God is spoken of as Spirit, never as Soul. The angels are also called spirits, but never souls. Trichotomy does not.
