From Greek Soma-Pneuma-eikon: Soma meaning body; Pneuma (spirit), and ikon derives from Eikōn meaning image. Literally, the Spirit Body Image.
"It is sown a soul body; it is raised a spiritual body. There is a soul body, and there is a spiritual body. And so it is written, the first man Adam was made a living soul; the last Adam was made a quickening spirit." - 1 Corinthians 15: 44, 45
