I cannot but help feeling that part of your difficulties are self-made. Is there such a difference between Jewish law and law in general? What is law—law in the abstract? What do you mean when you talk about laws of science or morality? Surely there is no such thing as law in the abstract. You really mean God's thought. All law existed long before this world existed, as the thought of God. This thought expresses itself, when the world is actually made, in animals, nature, man. But this thought is somewhat long before it expresses itself, because it is God's thought. With Him 'to think' is 'to do.' Before you and I were born, before men were made, man exists in God as a thought. Each of us is an expression of part of that thought. The whole thought is the image of God, not any one part. Now, when I speak of man as something in contra-distinction to men, I mean the thought of God in contradistinction to its individual realisation. So when I speak of law as distinct from special laws, I mean a thought of God as distinct from its special expressions. Otherwise 'man' and 'law' are abstractions and nonentities.
The nominalist is right in so far as he denies that law as an abstract thing (considered apart from a person—as his thought) is anything: the realist is right in so far as he affirms that law, apart from any particular manifestation, is an eternal reality. The reconciliation of nominalism and realism is found in God. Applying this to the case in hand—you admit that the Ten Commandments are the ground of morality; therefore, I say, they must be an expression of a thought of God, the Author of morality. But you are puzzled to find that the most trivial sanitary arrangements are considered by the Jew as equally a manifestation of God. Need we be? In every little sanitary precaution I recognise, or ought to recognise, an expression of that same mind as I see it in the Ten Commandments. God is Light, therefore the clean, the healthy, the decent is an expression of Him. God is Love, therefore the social, the self-sacrificing, is an expression of Him as well. But sanitary arrangements and the like, though an expression of an unchanging principle, change according to state of civilisation, climate, country. Therefore we take the principle, not the expression, as the ultimate reality in the case of these sanitary laws.
I am afraid I am rather stupid, and cannot make my meaning plain. I want to show you that the Jewish law only differs from English law as being in some ways a more complete expression of God's nature. But in all sanitary law, &c., now we have God's nature expressed. And it would be true to say, 'God spake unto England, saying'—e.g. in a right decision in court; it would be true to say, 'God spake unto the judge, saying.' Therefore, what holds good of Moses' law holds good of all law, because all law is a thought of God. Therefore St. Paul uses indifferently nomos and ho nomos, for what is true of God's thought is true of every expression of it. In fact, he more often perhaps argues about one particular expression of it. Why? Because we can only tell what the thought is by studying the expression.
[Transcriber's note: The Greek words in the above paragraph were transliterated as follows: nomos—nu, omicron, mu, omicron, final sigma; ho—(rough breathing mark), omicron]
Don't be taken in by abstractions. An ideal is nothing—worse than nothing—unless our ideal is God's idea. Then it is the only reality, because God's idea will take effect. His idea is to make man in His image, and be sure it will take effect. Commandments, judgments, statutes, mean much the same in the Old Testament, I conceive, as we mean when we use them. The Ten Commandments are not so called in the Bible, I think. They are called 'words,' I think.
I do not think St. Paul at all restricted nomos to the Ten Commandments. In fact, I don't know that he ever very clearly separated those off from all the rest.
Do not in your essay make the same mistake as many of the Jews in St. Paul's time. Do not try to consider law apart from the Law-giver. They looked upon law as a dead thing by itself, not as an expression of the character of a person.
Thus the Commandment about resting on the Sabbath day was considered by them as an order as though from a tyrant. But God, when He gave it, did not simply say, 'Here it is: do it'—but 'Do it because,' and He gives the reason why. The reason is different in Exodus and Deuteronomy, because the books were, to a certain degree perhaps, written to illustrate different aspects of God's character. Exodus says: 'Work and rest, because God's life is work and rest. Therefore human life made in His image is work and rest.' Deuteronomy says: 'Work and rest. God has emancipated you from slavery. He bids you rest.' In both cases God is the ground of the law. Study law—any law—English law—and in so far as it is law, and not lawlessness under guise of law, you will be studying God Himself; for if St. Paul's principles are true at all, they must be true of all law. But, oh! don't deal with abstractions, which sound well, but mean little. Let us use what we have. It is a grand thing to know that the highest ideal we can conceive must be realised, for the highest ideal must be part of God's idea.
Don't try to look at moral law apart from national life. St. Paul did not. Law is seen in national life. A nation is a better expression of God than an individual, because God is three, not simply one. He is a social Being, a Being of relations. And nations will last for ever. Law will always be seen worked out in national life. God has more worlds than one. Each nation is a thought of God worked out in human clay (cf. Jeremiah xviii. 1-6). Human clay lasts for ever ('I believe in the resurrection of the body'). Law will always be worked out thus. We are part of a thought of God—part of an English nation—little fragments of a huge whole. Our immortality depends on the fact that we are parts of a nation, parts of a Divine idea, which lasts for ever. Law is more completely seen in conscious than unconscious life, because God's life is conscious. Law is more completely seen in family and national than individual life, because in God Himself are seen the archetypes of human relations.
This letter is disjointed, but contains a few thoughts which may prove helpful—thoughts I have been learning from others of late.
