Now the peculiar character of the old covenant was that it dealt with men in the aggregate which we call the nation. Nationalism is the distinctive feature of the old world, within the precincts of Judaism and among the peoples of heathendom. Even the prophets could not see the spiritual truth, which they themselves foretold, except through the medium of nationality. The Messiah was the national king idealised, even when He was a Man of sorrows and acquainted with grief. In the passage before us the prophet Jeremiah speaks of God’s promise to write His law on the heart as made to the house of Judah and the house of Israel, as if he were not aware that, in so speaking, he was really contradicting himself. For the blessing promised was a spiritual and, consequently, personal one, with which nationality cannot possibly have any sort of connection. It is a matter of profound joy to every lover of his people to witness and share in the uprising of a national consciousness. Some among us are beginning to know now for the first time that a national ideal is possible in thought, and sentiment, and life. But there must not, cannot, be a nationality in religion. A moral law in the heart does not recognise the quality of the blood that circulates through. This truth the prophets strove to utter, often in vain. Yet the breaking up of the nation into Judah and Israel helped to dispel the illusion. The loss of national independence prepared for the universalism of Jesus Christ and St. Paul. Now also, when an epistle is written to the Hebrew Christians, the threatened extinction of nationality drives men to seek the bond of union in a more stable covenant, which will save them, if anything can, from the utter collapse of all religious fellowship and civil society. It is the glory of Christianity that it creates the individual and at the same moment keeps perfectly clear of individualism. Its blessings are personal, but they imply a covenant. If nationalism has been dethroned, individualism has not climbed to the vacant seat. How it achieves this great result will be understood from an examination of Jeremiah’s prophecy.
