42. Attribute to God, and not to self, whatever good you see in yourself.
59. Fulfill not the desires of the flesh; hate your own will.
60. Obey in all things the commands of those whom God has placed in authority over you even though they (which God forbid) should act otherwise, mindful of the Lord's precept, "Do what they say, but not what they do."
I'm not seeing a lot of room for free will in this document.
Whether one chooses good or evil, it is an exercise of one’s free will; but the purpose of human freedom (what it is) is that a human person can choose the good.
But what is “the good”?
For a modern treatment from a Christian perspective see Veritatis splendor:
59. Fulfill not the desires of the flesh; hate your own will.
60. Obey in all things the commands of those whom God has placed in authority over you even though they (which God forbid) should act otherwise, mindful of the Lord's precept, "Do what they say, but not what they do."
