I checked every place in the New Testament Moses, the Law, & commands are mentioned. Interesting that in the New Testament the law is always credited to Moses. The law of Moses.. Moses wrote.. Moses said.. It is called The Law, The Law of Moses.. We call it God's law & in the OT narrative it comes across that way but does the NT ever say it is God's law or the Lord's law or the Father's law?
Twice the law is said to have been "ordained by angels" it never says it was ordained by God.
In Romans Paul seems to call the Law of Moses "the law of God." However the only place He does this is at the end of chapter 7 which is immediately followed by Him talking about "the law of the Spirit of life in Christ Jesus." In 1 Corinthians 9:21 Paul confirms that the law of Moses is not the "law of God" he spoke about saying, "I too live apart from that Law (of Moses) so I can bring the Gentiles who are not under the Law (of Moses) to Christ. But I do not ignore the law of God; I obey the law of Christ." The law of Christ is the law of God, it is "the law of the Spirit of life in Christ Jesus." Thus Paul never calls the Law of Moses the Law of God.
Luke 2 is the only place in the entire New Testament, including the rest of the book of Luke, that the Law of Moses is called "the Law of the Lord." Contextually it only speaks of ceremonial law. Also of note is the fact that the Marcionite Gospel, which is likely an earlier version of Luke, does not contain the first two chapters of Luke. Luke 2 this is the ONLY place in all of the NT that calls the law the "Law of the Lord." There are times Jesus confirms commands as "of God" but He, nor any other NT person label the Law of Moses (as a whole) as the Law of God. Of note is that sometimes Jesus said "Moses commanded," other times He said "God commanded."
Perhaps most interesting of all is what Jesus says in John 15:25, "They have done this to fulfill the word that is written in THEIR Law, ‘They hated Me without a cause.’" Jesus calls the Law THEIR LAW, not His law, not His Father's law. Jesus never calls the Law "God's Law," "the Law of the Lord," or "my Father's Law."
Something to think about..
