Man and Sin by Piet Schoonenberg (1964) 1.6Z2

[In each one of us, God designed “something that could be better” and “something that has worked before and will keep on working”, that is: virtue and freedom.

Animals never worry about these issues.  They do not know any better.  They simply participate in a spontaneous order and do not worry about it.   Doesn’t that sound like a parable?]
