Yeah, I imagine you'd rebuke Paul for his opinion on eating meat offered to idols.
I mean, REAL Christians would never do that either.
Just as REAL Christians don't dance.
Just as REAL Christians don't drink alcohol AT ALL.
Just as REAL Christians don't smoke.
Just as REAL Christians don't play cards.
Just as REAL Christians don't play any sports on Sundays.
Just as REAL Christians don't shop on Sundays.
Just as REAL Christians don't cook on Sundays.
Just as REAL Christians don't drive cars on Sundays.
Just as REAL Christians don't associate with drunkards.
Just as REAL Christians ____________ (Fill in the blank as to what YOU feel makes a REAL Chritian)
Its quite obvious that anbody who does ANY of these things IS NOT a REAL Christian.
I would never rebuke Gods word concerning Christian liberty, but I would definitely come alongside a professing christian and reason with her that dressing immodesty damages the body of Christ and may tempt her brothers-in Christ to sin. If you love others, namely your sisters and brothers in Christ, you are a good role model for other woman and dress modestly, to leave no room for the enemy. 1 Tim 2:9
