Calvin, on the three parts of Christian Liberty

What is the nature of the freedom we have in Christ? Calvin distinguishes three parts (my paraphrase):

1. The consciences of believers must rise above the law, and think no more of obtaining justification by it.

2. Being freed from the yoke of the Law, the conscience freely and voluntarily obeys the will of God.

3. Finally, we are not bound by any indifferent (morally neutral) external thing, but are at liberty to either use them or omit them.
