Docetism

In the history of Christianity, docetism (from the Koine Greek: δοκεῖν/δόκησις dokeĩn "to seem", dókēsis "apparition, phantom") was the doctrine that the phenomenon of Jesus, his historical and bodily existence, and above all the human form of Jesus, was mere semblance without any true reality. Broadly, it is taken as the belief that Jesus only seemed to be human, and that his human form was an illusion.
