This study addresses the centrality of Christ in Paul's thought, recognizing at the same time that he does not express the meaning of Christ as an existing teaching. Christ as a person, not a teaching, determines Paul's thinking, for himself and in his reasoning with his readers. Christ comes to expression in Paul as the explication of the fundamental reality for himself and for his readers. He develops his thoughts about Christ in each case anew as expressions of the Lord who determines his life and the lives of his readers. In his reasoning with his readers, he expects them to become aware of Christ as the one who determines them in their new lives as believers.
