Plato elevates the spirit/soul as supreme and degrades the body as despicable. By dissociating the wholeness of man, he also discarnate the incarnated Christ

For Plato, man is dissociated into separate parts, the body is regarded as despicable and the spirit/soul as supreme, even divine. The result then is, there is no need for and no capability for true repentance and sanctification which involves man as a WHOLE. 

Professor Carsten Johnsen's book Agape & Eros, pg 223 states ..." The early Church was intensely aware of the simple fact that it is the goodness of God that "leadeth to repentance" (Romans 2:4). Our hope as Christians is that the One who loves us will give us repentance (2 Tim. 2:25). Metanoia has this in common with Agape. It is a source of rejoicing and sadness at the same time. It is a smile through tears. To be "sorrowed to repentance" is to be "made sorry after a godly manner." (2 Cor. 7:9) But that "godly sorrow worketh repentance to salvation not to be repented of" (verse 10), so rather a gladness-producing kind."  Read Johnsen's book here : http://www.temcat.com/L-4-Topical-Library/Sermons/AgapeEros.pdf 

It is repentance that causes our response as a WHOLE to God. The incarnate Christ makes us WHOLE, He writes the law bodily in our hearts when we respond unconditionally to love God with ALL our heart, soul and mind. 

Whilst Hinduism, Buddhism, Taoism meditative practices dissociate eastern minds ( and now the west ), Greek philosophy & Plato's spiritualism dissociates the west uniting the world in "pan-holyism", a unitive form of one world religion where bodies are unreal and the only reality is the soul/spirit, inherently supreme and perfectly pure, the Universal God Consciousness in-born in everyman. For the east " God is One, God is All". For the western Christian "Jesus One, Jesus All".... these mantras lead all to pantheistic Nirvana !
