The Greek word translated "unclean" actually should have been translated "common"
"Should have"
Your opinion? What is this based on?
He's not saying "clean/unclean" was nailed to the Cross because it's not Mosaic, but Noahic
Your opinion is that when Paul speaks of "unclean" things that he is exclusively talking about "unclean" things mentioned in Genesis? Do you have any evidence to support this?
Paul doesn't actually say that nothing should be considered unclean either. He says nothing is unclean in itself, but if a person of weak faith esteems something to be unclean, it is unclean to them. If you believe pork is unclean to you, it
is unclean to you. And fellow Christians are expected to respect that by not partaking of those things in front of a fellow believer that believes them to be unclean.
Isaiah 66:15-17 KJV is clear that when Jesus comes with fire at the Second Coming, among the "slain of the Lord" who will be "consumed together" will be those who eat unclean things.
"The end is near for those who ‘consecrate’ and ‘purify’ themselves to enter their cultic groves! They go in procession one after another into their ceremonies. They eat disgusting foods—pork, mice, and rodents." - Isaiah 66:17 TPT
Are you trying to use OT passages to negate NT passages?
Some of those instances of sobriety are more broadly talking about mental clarify (but certainly includes inebriation). Your opinion that "wine" could refer to non-alcoholic beverages is not consistent with scripture. Your opinion that Christians must completely abstain from alcohol is also not consistent with scripture.
"Likewise must the deacons be grave, not doubletongued, not given to much wine, not greedy of filthy lucre" - 1 Timothy 3:8 KJV
There are some Jewish texts and oral traditions that describe that dark beer is used to heal infections, and wine is used to heal sadness. These aren't inspired texts but may have been part of the culture of Jesus' day.
All of that said, if you believe that alcohol is unclean, it
is unclean to you. A loving brother or sister in Christ will abstain from alcohol when around you to respect that.
Let's be clear: that's the second "
new" commandment Jesus gave...which wasn't new at all (
Deuteronomy 6:5 KJV;
Leviticus 19:18 KJV) except to a people led by false Jewish prophets filled only with hate.
It's actually a common misconception that Moses' ten commandments were the firstmost commandments. There is nothing in scripture that says that the Mosaic ten commandments are first. And in fact, Jesus clarifies in the NT that the first and second commandment are "love God" and "love thy neighbour as thyself". Yes! You are correct to note Deuteronomy and Leviticus, a form of the first and second commandment do make an appearance in the OT.
The second of the ten commandments given to Moses is about idolatry, but second of the Mosaic ten commandments is not in fact the second commandment ("love thy neighbour" is).
In addition to not having any passage that states "this Mosaic commandment is the first commandment", different faith also have different interpretations of how the the Mosaic ten commandments are parsed. Not everyone uses the same list of "ten commandments".
we shouldn't get the idea the Two replace the Ten
Why would the first and second commandment be mutually exclusive with the ten commandments given to Moses? That reasoning makes no sense.
[the two] summarize the Ten.
No, they are the first and second commandments. Why argue with scripture?
The Ten Commandments are NT laws preached by James, Paul, Jesus, Peter, etc. And any New Testament Christian who thinks obedience to them are optional should read
1 John 2:3-4 KJV.
What is a "New Testament Christian"? I think the term you are looking for is just "Christian".
If it appears in the NT it is part of the NT covenant. If a NT passage says to "keep the commandments" it is talking about the commandments within the NT covenant. Yes, the NT covers common ground with the OT (with some differences). Do you agree with me now that you don't need the OT for moral direction? Every commandment that you claimed to be important exists in the NT.
