Man and Sin by Piet Schoonenberg (1964) 2.2 DY

Summary of text [comment] page 78

The limited goods (that a sinful person chooses) have a tendency to slip away. A sinful person may cling to a shred of virtue. But only for so long.

Schoonenberg wrote that fallen man is unable, without grace, to keep the commandments of the natural law for a long time.

[Why did Schoonenberg refer to ‘the commandments of the natural law’ and not ‘the divine law’?

Does Schoonenberg conflate thinkdivine and lawessential?

Or does his intuition implicitly comply with the explicit model of the intersection of virtue and sin?]
