True about humility. I don't mean to say that I can presume to know that what I do is not a sin.
My point was that even those who flee from any mention of a "teaching function" of the Law or a Third Use, still make judgements about what they and the church should do. Many who fear any use of the Decalogue because it fosters legalism, replace it with modern secular ideologies which are no less demanding. (Although far less realistic.) In the name of Gospel freedom God's Word is relativized, but it is only replaced with the latest fad of the right or the left.
I'm thinking of Luther's illustration of the simple servant girl who by doing her chores does a good work far more pleasing to God than all the works done by the religious of the day, because her obedience was commanded by God, while the works of the religious orders were self made.
An current example of this might be:
Don't worry, because you have been baptized, the prohibitions found in the Bible don't apply to you anymore! However, here are our new social statements. IF you don't subscribe to them THEN you are resisting the movement of the Spirit. Beware!
