Christ, ion resurrection, took on a new form. A body that was both physical (can be touched) and "spiritual" (more like thinking "ghost"). Yet Christ was always "spirit." (John 4) And Christ is life-giving. So in the context of a discussion on the nature of the body that is received in the resurrection, Christ "became" a life-giving "spirit." He already gave life. Now his body is different (and Paul is calling that body "spiritual").

Whatever it is that Lee said that keeps bringing this subject up is nonsense because Lee is talking about Christ (the Son, the 2nd of the trinity) becoming the Spirit (the 3rd of the trinity). Paul just does not say any such thing.
