Reincarnation is the process by which a spirit returns to be present in a new physical body to continue its continuous and infinite spiritual progress.
Present in the set of beliefs in Hinduism, Buddhism, Spiritualism among many other philosophical and religious systems, it was also present in Christianity until the Greek Orthodox Church removed from the Bible all references to reincarnation, which until then, around the first 3 centuries after Jesus’ death, was fully accepted as part of the Christian religion.
