I have voiced several concerns with Steven Paulson’s theology, but one of the most problematic portions of his thought is in his Lutheran Theology pages 103-105. His extremely convoluted manner of speaking suggests that Jesus himself actually sinned on the cross. This is no mere imputation of sins to Christ.
“[Jesus] wants to take your sins and leave it to no one else; so he sins against the Golden Rule.” (Lutheran Theology, 103).
“When Christ took sin by association, he not only transgressed the law, but placed himself “under an evil lord.” (Lutheran Theology, 104).
“Christ comes to believe he was guilty.” (Lutheran Theology, 105).
“Confessing made it so, and thus Christ committed his own, personal sin—not only an actual sin, but the original sin.” (Lutheran Theology, 105).
“Fifth, Jesus could not seem to stop himself once this sin began rolling downhill, not only did he confess our sins as his own (and believed it), but he proceeded to take on every single sin ever committed in the world: “I have committed the sins of the world” (“Ego commisi peccata mundi”).” (Lutheran Theology, 105).
Read the section yourself, and come away with whatever conclusion you will, but as far as I know, Paulson has not publicly corrected these comments.
