What I see here are symptoms of trying to live the Christian life by works instead of grace.
We are saved by grace
We live our Christian life by grace
We are glorified by grace.
The problem is with many Christians is that they are saved by grace, and then suddenly they find themselves trying to live the Christian life by works. This is shown by trying to keep to the "rules", or to the expectations of others to win their approval. If a church or a person induces another to behave in a certain way in order to get their approval, then they are shifting that person away from grace to self-effort, based on works, which leads to self-righteousness.
The truth is that when a person accepts Christ, he or she is totally cleansed and forgiven, and now has the full and permanent approval of God. Paul said this to the Galatians. He asked them why, having started by grace through faith, why are they trying to make the goal through their own works?
We live in obedience to God because we are already approved by Him, not to gain His approval. And when we are already approved by God, then we don't need anyone else's approval at all. If a church or person demands that we live a certain way to maintain their approval, they are not in the Spirit, but are forcing the demans of the flesh on us. We have every right to refuse to live up to anyone's set of rules of principles in order to gain their approval.
We live our lives by the grace of God and under the light of His approval. We obey God out of our love for him.
If a church or person demands a certain way of behaviour in order to gain approval, part company with them because they will drag you down into the same grievous sin that they are wallowing in. The Scripture says that they who are in the flesh cannot please God. Justification is by grace through faith, and once we are justified, we live under the full approval of God. That is true Christian freedom - to live as guided by the Holy Spirit and not under the yoke of demanding and judgmental neo-pharisees who want to exercise power and control over us.
God does not view us according to our performance. He views us through the Righteousness of Christ which He has bestowed on us through grace. It doesn't matter what we do, we will always be approved of God. This is what justification is all about. If we do good, this does not make us any more approved of God than the grace He gave us when we first came to Christ. If we mess up, He does not take His approval away. This should set us free from the continual sinning-repenting syndrome brought about by seeking approval when we mess up, and seeking more approval if we do something good. Doing this is trying to get there by works instead of resting in the grace of God.
Of course, sanctification is another issue, but this is not generated by others demanding obedience to their rules. It is being led by the Holy Spirit in love, peace and joy, and in close fellowship with God.
