Many parallels in themes, phrases, and motifs have been detected between the Hellenistic–Jewish romance Joseph and Aseneth (JosAs) and the letters of Paul. This article argues that common motifs and also the specific theological profile originate in the same speculative or dualistic branch of wisdom theology. The first part detects wisdom theology as a basic structure of the narrative in JosAs. The second part argues for wisdom theology in Colossians, 1 Cor 1–2 and Phil 3. Paul contrasts wisdom and the cross. However, important motifs are shared by Paul with wisdom theology, and he formulates his Christology as wisdom theology in a dialectic fashion.
