So you believe these "Noahide" laws found in Acts 15 are to be kept by the church
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. Its there we find that we are to be keeping Gods sabbath day.
Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; And shewing mercy unto thousands of them that love me, and keep my commandments.
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 don’t know what the connection might be as to why graven images and idols are a sign that you don’t keep Gods sabbath but if the WORD says so I believe it. We could have a debate on what an idol is but that would go nowhere but in circles. Does your church have any standing images? I know the churches that do keep the sabbath don’t have any standing images or crosses.
