With this speech Zinzendorf was delighted. As the little difficulty about the certificate had not yet been cleared away, he suggested that the person bringing the certificate should bring witnesses as well; and with this trifling amendment the Bill at last--on May 12th, the Moravian Memorial Day--was carried without a division. In one sense this Act was a triumph for the Brethren, and yet it scarcely affected their fortunes in England. Its interest is national rather than Moravian. It was a step in the history of religious toleration, and the great principle it embodied was that a religious body is entitled to freedom on the ground of its usefulness to the State. The principle is one of the deepest importance. It is the fundamental principle to-day of religious liberty in England. But the Brethren themselves reaped very little benefit. With the exception of their freedom from the oath and from military service, they still occupied the same position as before the Act was passed. We come here to one of those contradictions which are the glory of all legal systems. On the one hand, by Act of Parliament, they were declared an Episcopal Church, and could hardly, therefore, be regarded as Dissenters; on the other, they were treated as Dissenters still, and still had their churches licensed as "places of worship for the use of Protestant Dissenters."[126] CHAPTER XIII. -- THE BATTLE OF THE BOOKS, 1749-1755. As soon as the Act of Parliament was passed, and the settlement at Herrnhaag had been broken up, the Count resolved that the headquarters of the Brethren's Church should henceforward be in London; and to this intent he now leased a block of buildings at Chelsea, known as Lindsey House. The great house, in altered form, is standing still. It is at the corner of Cheyne Walk and Beaufort Street, and is close to the Thames Embankment. It had once belonged to Sir Thomas More, and also to the ducal family of Ancaster. The designs of Zinzendorf were ambitious. He leased the adjoining Beaufort grounds and gardens, spent £12,000 on the property, had the house remodelled in grandiose style, erected, close by, the "Clock" chapel and a minister's house, laid out a cemetery, known to this day as "Sharon," and thus made preliminary arrangements for the establishment in Chelsea of a Moravian settlement in full working order. In those days Chelsea was a charming London suburb. From the house to the river side lay a terrace, used as a grand parade; from the bank to the water there ran a short flight of steps; and from there the pleasure-boats, with banners flying, took trippers up and down the shining river. For five years this Paradise was the headquarters of the Brethren's Church. There, in grand style, lived the Count himself, with the members of his Pilgrim Band; there the Brethren met in conference; there the archives of the Church were preserved; and there letters and reports were received from all parts of the rapidly extending mission field.
