Perhaps you could enlighten me, then, as to exactly which OT statues apply and which do not.
I would like to enlighten you.
We don't have to observe special days anymore because all those special days were about Jesus and now we don't observe days but we are to observe Jesus all day every day.
The males don't have to be circumcised in the flesh; we all only have to be circumcised in the heart by Jesus when we receive his Spirit.
We are no longer separated as a people by the kind of food we eat and how we cook; we are separated now by who obeys and who doesn't.
We don't have to do external baths anymore before we go to the temple to worship God; we are washed by the Spirit by obedience to the words of God.
No more sacrificing animals because Jesus' blood cleans us once and for all.
We don't even have to go to the temple because we become the temple.
No more cutting off the hand for hand and foot for foot and eye for eye.
No more stoning to death for adultery and other things.
No more three divorces.
Hair length and beards and covering is cultural, because Paul says by nature we see it.
You're clearly happy to accept that some don't but seem to consider it perfectly acceptable that the marketing department of a clothing manufacturer gets to decide whether it's sinful for me to wear this garment or that garment.
They wear what fits and is comfortable. It doesn't seem like such an unreasonable thing to do.
God knows you don't care.
