In Mathew Christ says
17 “Do not think that I came to destroy (καταλύω)(throw down,do away make void) the Law or the Prophets. I did not come to destroy but to fulfill.
But the Apostle Paul says in
15 having abolished (καταργέω) (do away,cease,put away)in His flesh the enmity, that is, the law of commandments contained in ordinances, so as to create in Himself one new man from the two, thus making peace
Paul goes further in (Romans 7:6) to reinstate his position concerning the law & I have been trying to reconcile the above texts but I'm finding it hard to understand the concept
