Melon, you seem to have a good knowledge of Christian history. I love that you quoted Paul here: ""For freedom, Christ has set us free; stand fast therefore, and do not submit again to a yoke of slavery. Now I, Paul, say to you that if you receive circumcision, Christ will be of no advantage to you. I testify again to every man who receives circumcision that he is bound to keep the whole law. You are severed from Christ, you who would be justified by the law; you have fallen away from grace. For through the Spirit, by faith, we can wait for the hope of righteousness. For in Christ Jesus neither circumcision nor uncircumcision is of any avail, but faith working through love." -- Galatians 5:1-6.
I find interesting that you didn't quote Paul a few sentences later in Galatians 5:13: "You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature"
And what does the very same Paul write are the acts of the sinful nature? Thank the Lord he answers this question in the very same chapter in Galatians 5:19- "The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God."
Christian freedom is about being free from the bondage of the sinful nature, bot about doing what you want.
