The law of sin and death is most emphatically the law of Moses.
The law of the Spirit of life in Christ Jesus is grace.
Surely you can read - go through the rest of Romans chapter 8.
As for Acts chapter 15 - the whole debate was whether the Mosaic law was binding on believers - the conclusion was that it was NOT - I am sorry you never got that but it is blindingly obvious to a cursory read.
I have addressed what I deem to be your error concerning Romans above.
But here in acts 15 I did not speak so I thought I owe you some sort of response. It is interesting that you say at a cursory read its obvious. I would say that about reading the law that its obvious that the ceremonial law and the 10 commandments are not the same nor the Leviticus law the same. Yes they are all related no doubt but you get the point.
If we are going to just read as it writes then you should acknowledge that the main issue being brought fourth is:
Act 15:1 And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.
Yes the issue is circumcision not the whole law if it was the whole law then even this would be left out of the teaching:
Deu 6:5 And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
So very clearly as both you and I would agree that they would have been taught to love God with all their heart etc we can clearly see that the issue is not the whole of the laws found in the law of Moses from God.
It seems you bunch it all together so you must believe that the Apostles taught not to obey thou shalt not kill? No of course you don't so then its clear that the law that says thou shalt not kill would not be an issue for the disciples in fact they taught such things. Jesus taught it in more depth.
So even you don't really believe the 10 commandments spoken by God and written with His finger are in view in this chapter. You certainly could not prove they are. or are you inconsistent with your own views.
If Paul had the law of God in view here which according to Paul are the 10 commandments then you have Paul going against himself.
Paul in fact taught this:
Rom 13:8 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
Rom 13:9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
Rom 13:10 Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.
Paul taught to keep at least 6 of the ten and he is quoting them. He puts them in their proper setting which is love, Love will not bear false witness or kill or steal etc. Then he says these of the 10 are comprehended or understood in this saying:
Thou shalt love thy neighbour as thyself.
Guess what that is the law of Moses you seem to think Paul taught against.
Lev 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people,
but thou shalt love thy neighbour as thyself: I am the LORD.
I think this is proof enough that it is not as you say.
