Romans Chapter 14 say's what?

It's commonly taught that Paul wrote to the assembly in Rome saying the 7th day Sabbath doesn't matter and Pork and Shellfish is no longer unclean but was that the case?

Rom 14:5 One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
This verse has a common interpretation which states that Paul was saying that it doesn't matter what day you choose to worship on, therefore it's O.K. to worship on Sunday (this line of reasoning also extends to Yahweh's Feast's). The 1st problem, of course, is that Paul would be teaching a doctrine completely contrary to the Gospel of Christ and the Law of Yahweh. Paul actually say's in this very same letter that it is the doers of the Law that will be justified.
Rom 2:13 For not the hearers of the law are just before Elohim, but the doers of the law shall be justified.
This statement by Paul is in clear agreement with the Gospel of Messiah.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
If Paul was teaching a doctrine of disobedience to Christ and the Father we would do well in saying he was a false teacher.
Isa 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
The 2nd problem is that the Sabbath isn't even mentioned in the entire letter to the Roman assembly. Paul is clearly talking about eating certain things and not eating certain things and not eating at all on certain days. Look at the verses before verse 5.
Rom 14:2 For one believeth that he may eat all things: another, who is weak, eateth herbs. Rom 14:3 Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for Elohim hath received him.
Verse 6 brings it all together.
Rom 14:6 He that regardeth the day, regardeth it unto the Master; and he that regardeth not the day, to the Master he doth not regard it. He that eateth, eateth to the Master, for he giveth Elohim thanks; and he that eateth not, to the Master he eateth not, and giveth Elohim thanks.
Paul is talking about days of fasting which is in perfect alignment with Gospel of Yahshua.
Mat 9:14 Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not?
Mat 9:15 And Yahshua said unto them, Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and THEN SHALL THEY FAST.
Yahshua gives instruction, saying that His disciples will fast but does not specify what days to fast on. It makes sense that believers would write to Paul asking him for clarity on this. If the subject was indeed about the Sabbath, Paul would have mentioned working and/or not working being the issue, since the commandment is about a day of rest, but he doesn't. He is clearly talking about eating and not eating.
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of Yahweh thy Elohim: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days Yahweh made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore Yahweh blessed the sabbath day, and hallowed it.
Yahweh blessed the 7th day and set it apart (hallowed) from the other 6 days. Those that teach that the Sabbath moved to Sunday always seem to refer to it as a day of worship but the commandment calls it a day of rest (Sabbath means rest). Paul was not a false teacher as he did not teach against the Law nor did He teach against the Doctrine of Messiah. The person who commanded the move to Sunday was Constantine in 321 A.D. The Catholic organization takes full credit for this in a publication called "Rome's Challenge Why do Protestants keep Sunday".

What about unclean foods now being clean. Paul clearly say's so in Romans chapter 14 right?
Rom 14:14 I know, and am persuaded by the Master Yahshua, that there is nothing unclean(koy-nos) of itself: but to him that esteemeth any thing to be unclean(koy-nos), to him it is unclean(koy-nos).
The King James Bible translates the word "koy-nos" in this passage as unclean. No where else is it translated to mean unclean. It is translated in most places as the word "common". The Strong's does use unclean as one of its definitions (due to doctrinal influence I'm sure), but it cannot possibly mean unclean. Look at the verse below.
Jud 1:3 Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.
Jude uses this same word in relation to salvation. How could this word possibly mean unclean? Let's look at another verse.
Acts 4:32 And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common.
None of the early believers considered their possessions as their own and had all things unclean? No, of course not... They had all things common.
Mar 7:2 And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.
The same word here is translated Defiled. The context in Mark chapter 7 and Matt chapter 15 is not about unclean meats or anything commanded in the Law but rather it is about man made traditions pertaining to Judaism that were actually contrary to the Law. Yahshua clarifies His response to His disciples.
Mat 15:16 And Yahshua said, Are ye also yet without understanding?
Mat 15:17 Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?
Mat 15:18 But those things which proceed out of the mouth come forth from the heart; and they defile(koinoō) the man.
Mat 15:19 For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies:
Mat 15:20 These are the things which defile(koinoō) a man: but to eat with unwashen hands defileth(koinoō) not a man.
I believe Paul, as a minister of the Gospel, was referencing this teaching of Yahshua when he stated that he was persuaded by Him.
Rom 14:14 I know, and am persuaded by the Master Yahshua, that there is nothing common(koy-nos) of itself: but to him that esteemeth any thing to be common(koy-nos), to him it is common(koy-nos).
The Greek word for unclean is "ak-ath'-ar-tos" and Paul used it in the verse below while quoting the Prophet Isaiah.
2Co 6:17 Wherefore come out from among them, and be ye separate, saith Yahweh, and touch not the unclean(ak-ath'-ar-tos) thing; and I will receive you.
This word is translated "unclean" in every instance in the int the King James Bible with the exception of 2 places where it is translated "foul". This is the word that Paul would have used in Romans chapter 14 if he was guilty of saying what he is accused of saying.
