In short, "Nope", we don't gotta keep them...
5 But some believers who belonged to the party of the Pharisees rose up, and said, "It is necessary to circumcise them, and to charge them to keep the law of Moses."...
22 Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsab'bas, and Silas, leading men among the brethren, 23 with the following letter: "The brethren, both the apostles and the elders, to the brethren who are of the Gentiles in Antioch and Syria and Cili'cia, greeting. 24 Since we have heard that some persons from us have troubled you with words, unsettling your minds, although we gave them no instructions, 25 it has seemed good to us, having come to one accord, to choose men and send them to you with our beloved Barnabas and Paul, 26 men who have risked their lives for the sake of our Lord Jesus Christ. 27 We have therefore sent Judas and Silas, who themselves will tell you the same things by word of mouth. 28 For it has seemed good to the Holy Spirit and to us to lay upon you no greater burden than these necessary things: 29 that you abstain from what has been sacrificed to idols and from blood and from what is strangled and from unchastity. If you keep yourselves from these, you will do well. Farewell. - Acts 15
This is what ive talked about earlier.

You have taken a scripture that is clearly speaking of circumcision and applied it to the 10 commandments
As for acts 15
ACTS 15 [17] That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things. [18] Known unto God are all his works from the beginning of the world. [19] Wherefore my sentence is, that we trouble not them, which from among THE GENTILES are turned to God: [20] But that we write unto them, that THEY ABSTAIN FROM POLLUTIONS OF IDOLS, and from fornication, and from things strangled, and from blood. [21] For Moses of old time hath in every city them that preach him, being read in the synagogues every sabbath day.
ACTS 15 as a whole was speaking as to whether gentiles needed to be circumcized or not.
ACTS 15 [4] And when they were come to Jerusalem, they were received of the church, and of the apostles and elders, and they declared all things that God had done with them. [5] But there rose up certain of the sect of the Pharisees which believed, saying, That IT WAS NEEDFUL TO CIRCUMCISE THEM, and to command them to keep the law of Moses.
ACTS 15 [24] Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying, YE MUST BE CIRCUMCISED, and keep the law: to whom we gave no such commandment:
Nothing to do with the 10 commandments. So lets look into what pollution of idols {V 20} is all about. What I found was very as always, when you let scripture interpret scripture
LEVITICUS 19 [3] Ye shall fear every man his mother, and his father, and KEEP MY SABBATHS: I am the Lord your God. [4] TURN YE NOT UNTO IDOLS, NOR MAKE TO YOURSELVES MOLTEN GODS: I am the Lord your God.
LEVITICUS 26 [1]Ye shall MAKE YOU NO IDOLS NOR GRAVEN IMAGE, neither rear you up a standing image, neither shall ye set up any image of stone in your land, to bow down unto it: for I am the Lord your God. [2] YE SHALL KEEP MY SABBATHS, and reverence my sanctuary: I am the Lord.
EZEKIEL 20 [16]Because they despised my judgments, and walked not in my statutes, BUT POLLUTED MY SABBATHS: FOR THEIR HEART WENT AFTER THEIR IDOLS.
I dont know what the connection might be as to why graven images and idols are a sign that you dont keep Gods sabbath but if the WORD says so I believe it. I know the churches that do keep the sabbath dont have any standing images or crosses. Well, least the ones I know. Also, the guys and gals that go to these churches dont wear molten gods about their necks.
