Okay, I went super dork and just outlined everything. I've actually been trying to answer these questions in my mind for a year so here are my catagories I see in Augustine:
1. Liberty to sin, Freedom of directing the Will - Free Choice
pg 16 -[God does not cause sinners to sin]- "but of sinners only the orderer."
pg 28 - "Lord, and by the law written in the hearts of men which not even iniquity itself destroys."
pg 38 -"The liberty I loved was merely that of a runaway."
pg 68 - "'why then does God err?' I used to argue that your unchangable substance is forced into mistakes rather than confess that my mutable nature deviated by its own choice and that error is its punishment."
pg 113 - "I directed my mind to understand what I was being told, namely that the free choice of the will is the reason why we do wrong and suffer just judgement."
pg 114 - "people suppose that evil is something that you suffer rather than an act by humanity."
pg 138 - "Human beings obtain normal pleasures of human life not as they come on us unexpectedly and against our will, but after discomforts which are planned and accepted by deliberate choice." [Our discomfort is chosen]
2. Liberty from sin
pg 13 - "Deliver also those who do not as yet pray, that they may call upon you and you may set them free"
pg 107 - "Like a man whose wound has been hit, I pushed aside the words of good advice like the hand loosing the bond."
pg 120 - "[I am] inferior to you, and you are my true joy if I submit to you."
pg 140 - [New will, old will free?] "The new will, which was beginning to be within me a will to serve you freely and to enjoy you..."
