Man and Sin by Piet Schoonenberg (1964) 2.3 CE

Summary of text [comment] page 82

Schoonenberg reiterated the point.

In Church doctrine, concupiscence is a sequel to Original Sin.

This statement reflects a dualism in Greek philosophy. Concupiscence implies ‘the flesh as opposed to reason’. Since concupiscence is not subject to reason, it is regarded as bad.

This raises a question:

Can reason participate in concupiscence? Does concupiscence include reason?
