Romans 10:4 For Christ is the end of the law for righteousness to everyone who believes.
[from www.christadelphianbooks.org/agora/comm/45_rom/rom11.html] Those who believed in Christ Jesus as the means of God's bestowal of righteousness saw the complete eclipse of law (any law, the definite article is not in the original) as a means to the attaining of righteousness for man.
END: Just as in English we speak of "the end of the matter" and use the expression "to the end that" -- in the one expression "end" meaning conclusion or termination, and in the other, goal or purpose -- the same dual possibility lies in the Greek word "telos". The work of God in Christ both put an end to the Law, but it also fulfilled the goal or purpose of the Law, which was a "schoolmaster" or "guide" to point the way and to lead others to Christ (Galatians 3:24)! In a similar vein, Jesus said, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them" (Matthew 5:17). But in being fulfilled, in and through Christ, the Law -- by necessity -- came to its end or conclusion.
In Christ, the Law came to an end in the same way that the seed comes to an end in the new plant that springs up, or the bud comes to an end in the blossoming flower. "The new is in the old concealed; the old is in the new revealed."
