Summary of text [comment] page 67

Schoonenberg wrote that “with mortal sin, the sinner ‘himself’ refuses grace. ‘He’ throws off the life of grace. Or, the sinner may usurp it, pretending that it is ‘his’ to own. Then, it slips from ‘his’ grasp.

This loss of sanctifying grace is represented as punishment. Sin itself punishes the sinner by robbing ‘him’ of the life of grace.

[Schoonenberg’s scenario sounds circular. The sinner deprives ‘himself’ of the life of grace by sinning. The sin itself robs him of the life of grace.]
