Like I've said, the soul (mainstream Christian understanding) is the esssence of a person not in any way physical. Yes it's a supernatural thing and as such can't be evidenced empirically.
wikipedia Wrote:The majority of Christians understand the soul as an ontological reality distinct from, yet integrally connected with, the body. Its characteristics are described in moral, spiritual, and philosophical terms. When people die their souls will be judged by God and determined to spend an eternity in heaven or in hell. Though all branches of Christianity –Catholics, Eastern Orthodox and Oriental Orthodox, Evangelical or mainline Protestants – teach that Jesus Christ plays a decisive role in the salvation process, the specifics of that role and the part played by individual persons or ecclesiastical rituals and relationships, is a matter of wide diversity in official church teaching, theological speculation and popular practice. Some Christians believe that if one has not repented of one's sins and trusted in Jesus Christ as Lord and Saviour, he/she will go to hell and suffer eternal separation from God. Variations also exist on this theme, e.g. some which hold that the unrighteous soul will be destroyed instead of suffering eternally. Believers will inherit eternal life in heaven and enjoy eternal fellowship with God. There is also a belief that babies (including the unborn) and those with cognitive or mental impairments who have died will be received into heaven on the basis of God's grace through the sacrifice of Jesus.http://en.wikipedia.org/wiki/Soul#Christianity
