Man and Sin by Piet Schoonenberg (1964) 2.3 BP
Summary of text [comment] page 82
Schoonenberg considered ‘the flesh’ in the context of concupiscence and bondage.
He asked: How does this word appear in history?
The term ‘flesh’ derives in part from the Greek world. The Greeks came to see that ‘the flesh’ was opposed to ‘reason’.
In the Old Testament, ‘the flesh’ was opposed to ‘the Providence of God’.
[Notably, Schoonenberg did not mention the older opposition, flesh versus blood & bones. Obviously, blood & bones were attuned to the Providence of God.]
In the New Testament, flesh joins desire as ‘belonging to the world’ as opposed to ‘belonging to the Father (1 John 2:16)’.
Schoonenberg concluded that ‘concupiscence’ is a pejorative term that represents the tendency toward sin within man or mankind as it stands under sin.
