So New Testament (Covenant) commands do not have to be obeyed—got it.
BTW, the ten commandments were never designed to save anyone, so that straw man argument is in the circular file.
All that "newness of life" jazz is just twisting of Paul's words to provide a self-deceptive loophole for disobedience but, all too late for many, it will be found to have had all the strength of a rope of sand.
What do you make of this:
1 Peter 3
2While they behold your chaste conversation coupled with fear. 3Whose adorning let it not be that outward adorning of plaiting the hair, and of wearing of gold, or of putting on of apparel; 4But let it be the hidden man of the heart, in that which is not corruptible, even the ornament of a meek and quiet spirit, which is in the sight of God of great price.
1 Timothy 2
9In like manner also, that women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array; 10But (which becometh women professing godliness) with good works.
Er, uh...
No, the NT commands are for obedience. Not to gain righteousness, or add righteousness or enhance our salvation etc.etc.etc., but we live in them to show we are righteous through the new life!
I can't speak about those who wish to use "newness of life" as an exuse for disobedience, but I know the command are for us to live by to show we have been made righteous. There is a huge difference between people doing works to be righteous and those doing works because they are righteous through the blood Jesus shed.
I agree with those two verses about women and their outer appearance. But Peter and Paul are addressing how a woman shows her true beauty versus just outer stuff. It is a matter of attitude of the heart more than just what one is wearing. If we were to take this fully literally- Braids and hairdos, jewelry (even an engagement ring), and clothing of any other but the most basic sort is forbidden. But both apostles are contrasting a material and worldly way a woman seeks to highlight beauty versus how a godly woman should highlight her beauty.
It is no sin to wear jewelry or have nice clothes if the heat is right in wearing them.
