Christopher G. Foster identifies Jewish mystical elements in the Dead Sea Scrolls and compares them with analogous features in the Corinthian correspondence to illuminate through differences and similarities how Paul advocates a mystical and communal participation in the Spirit.

Part II compares these findings with corresponding aspects in 1 and 2 Corinthians to demonstrate the largely corporate tenor of participation and transformation in and by the spirit for Paul.
