Over recent weeks and months the idea that Jesus came to fulfill the law, rather than to abolish it (Matt 5:17) has been mentioned quite often. Quite understandably, some here have asked what that phrase means.
We recently had a sermon on this very passage at church which can be listened to at
http://www.tabspenarth.org.uk/series/the-beatitudes. It is the 4th sermon down, July 5th.
However, I will try to precis it here, as well as adding a few thoughts that I've gleaned though some research I've been doing.
Firstly, we need to decide what 'the law' is. In the context of the passage in Matthew, it is the Old Testament/Hebrew Law that was given to the people of Israel over a period of time starting with the 10 Commandments. Notice at which point it was given - it wasn't at the point that they started out as a tribal group; it occurred at a point when they had begun to grumble about the hardships that they faced in the early days of their travels through the Wilderness of Shur (Exodus 15:22 onwards). In other words, law is there to control human failings and failings of social cohesion. In a perfect society, law would not be required.
The apparently vicious creed of an eye for an eye, tooth for tooth is often quoted in this context, suggesting that it simply highlights the barbarity of those people who applied it. I would ask, don't we, in 21st Century Britain seek to do the same thing - make the punishment fit the crime? An eye for an eye, tooth for tooth was all about ensuring that retaliation/punishment is limited and proportionate.
Is all law good law? No. History is peppered with unjust laws which oppressed and marginalised the poor and vulnerable, whilst improving the lot of the already-powerful. Equally, history is peppered with laws which address(ed) social mores that were, in reality, totally unacceptable even at the time, but occurred because of tradition.
Jesus, in the Sermon on the Mount, is talking about a very different level of living to that which existed then and still exists today; a level of living where we live rightly (righteously, in Bible- speak) not because we are compelled to do so by law but because we want to - thus dispensing with the need for law.
In other words, 'fullfilling the Law' doesn't involve making the law obsolete, but making it unnecessary. 'Obsolete' implies that it has been superseded by something of the same order, and Jesus taught that God simply isn't interested in ever-escalating levels of law.
The preacher referenced one of his favourite fictional characters towards the end of the sermon. Jack Ryan, the main character in many of Tom Clancy's novels, has a saying - "If you have to write down your code of ethics, you've already lost".
