A History of Moral Philosophy in a Few Sentences

In Atheist Delusions, David Bentley Hart makes an attempt at summing up the moral frameworks of modernity and Christianity. How well do you think he does?

Modernity:

"It is choice itself, and not what we choose, that is the first good..."

Christianity:

"...we are free not merely because we can choose, but only when we have chosen well."

To sum up the summary:

For modernity, the good is our ability to choose, and in having that choice we enjoy freedom.

For Christianity, the good is what we must choose, and in making that choice we enjoy freedom.
