ANSWER: He teaches that body and soul constitute man. He does not believe there are three distinct essentials in man, but two only, that the human spirit is not an entity, but the soul's capacity to be quickened into spiritual life by the life-giving Holy Spirit received by faith in Jesus Christ. Wesley means that spirituality cannot be predicated of the natural man before regeneration. He had no sympathy with the widely spreading modern error that immortality is not of nature, but is the gift of God for believers only. He believed in the eternal punishment of the finally impenitent rejector of Christ. Of modern contemporary theologians Holsten and Weiss deny the existence of a πνεῦμα (pneuma, spirit) in the natural man, thus confirming Wesley's doctrine.
