It's possible though that you don't understand me, so I will clarify. The morality, or "perfect will of God" as St. Paul put it, was always there, but God gave a lesser version appropriate for the times , intending to bring them out of it in the future .
Augustine felt that human beings were dumbed down from sin, so the right thing isn't obvious to them. The word "wisdom" has relevance here. From the NT:
"But the wisdom from above is first of all pure, then peaceable, gentle, accommodating, full of mercy and good fruit, impartial, and sincere." From the other lines as well around it, it seems that Paul thought a person who is like this - arriving at perfection - would have this intuitive ability within to know how they should conduct themselves worthily, and would live in such an excellent manner. They would be able to apply that finer morality in less obvious instances , and so live a perfect life.
