Works of the law are circumcision, observance of special days, eating and drinking rules, gift offerings, sin offerings, external washings for an earthly tabernacle.
Rom. 2:17 ¶ 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.
Moriah, do you see the repetitive "the law" throughout this section? Do you see it includes the ten commandments (vv. 21-22) as well as circumcision in the same law (vv. 25-27).
"Works" are what YOU DO and "the law" is what REVEALS to you what God wants you to do!
18
And knowest his will, and approvest the things that are more excellent, being instructed out of the law;
Hence, the "works of the law" are what YOU DO TO PLEASE GOD'S REVEALED WILL.
So YOUR idea that "the works of the law" include only the ceremonial aspects of "the law" is repudiated by Paul completely and thoroughly not merely in Romans 2 but throughout Romans chapters two through chapter 7.
So don't tell us that the "works of the law" only include circucmision but do not include the ten commandments as Paul says the ten commandments along with circumcision are included in the works of "the law" in Romans 2 as well as in Romans 7.
