Meta. The word body is used in the English Bible to translate many Hebrew words, from carcass to soul. The body is the material manifestation of the life principle. It can seem to be merely a carcass or it can be an incorruptible habitation of the Spirit, depending on the spiritual unfoldment of the individual whose body it is.
Body is just as essential a part of man as soul or spirit. Creation is not complete until it becomes manifest in the outer, and man must have a body through which to express his ideas. Jesus' resurrection was bodily as well as spiritual.
