***If the ten commandments were ENDED, that would mean MURDER was acceptable and fine with God.***
No, even Cain had a mark placed on him. What he did was NOT acceptable to God, and the Ten Commandments had not been given then.
Romans2:
12 For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.
14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)
17 Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,
18 And knowest his will, and approvest the things that are more excellent, being instructed out of the law;
19 And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,
20 An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
21 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?
22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
24 For the name of God is blasphemed among the Gentiles through you, as it is written.
25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Romans7:
4 Wherefore, my brethren, ye also are become dead to the LAW by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
5 For when we were in the flesh, the motions of sins, which were by the LAW, did work in our members to bring forth fruit unto death.
6 But now we are DELIVERED FROM THE LAW, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I HAD NOT KNOWN LUST, except the LAW had said, THOU SHALT NOT COVET.
8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead.
PLEASE NOTICE that St Paul does not distinguish between ceremonial and THE TEN COMMANDMENTS. He constantly refers to them as THE LAW.
