The precise nature of the σῶμα πνευματικόν (the enspirited body) remains a mystery. It is possible that Paul derived the expression from a lost source in Alexandrian Judaism - perhaps based on a transformation of the exegesis of the Genesis creation tradition - but it seems most probable that the origin of the concept was his self-described experience of the Risen Lord. σῶμα πνευματικόν does not appear in any text datable prior to 1 Corinthians. However, John Granger Cook shows that 1 Cor 15:35-58 and 2 Cor 5:1-10 do provide some guidelines for understanding Paul's concept of the enspirited body and enable the reader to make useful conclusions about what a σῶμα πνευματικόν is and what it is not. The context of "enspirited body" indicates the following result: the claim occasionally seen in modern scholarship that the enspirited body in Paul is entirely non-physical is unwarranted.
