Thus the key to the physical conception of the Universe is to be found, and alone found, in that beauty of order, and harmony of motion, which are so inseparably associated with the varied forms of matter, graduating through a series of units or atoms, each with its dual nature complete in itself, through a series of minor entities termed elements, which in their aggregations form meteorites, satellites, planets, suns and stars, and systems of stars and oceans of suns and stars, until all are united into one ultimate unity where all are blended into one complete and perfect whole; the whole of the universal fabric being held together in its mechanical order and beauty by the electro-magnetic Aether. Then in the very centre of the Universe there dwells that Supreme Being whom we call God, who is at once the one real fountain and source of all the light and life of the Universe itself. For it is His universal Spirit that moulds and fashions the plastic matter into the many forms which it assumes, and uses the various modes of motion, as heat, light, electricity and magnetism, as instruments to build up and erect in all their beauty and harmony the innumerable systems that flood immensity and space. For if there be a centre of gravity to an atomic system, and a centre of gravity to a planetary system, and a centre of gravity to a solar system, then there is also a centre of gravity to a group of systems, even to a constellation, or a galaxy; otherwise our philosophy relative to the centres of gravity of masses fails in its application to wider phenomena of an exactly similar kind. Thus, if there is a centre of gravity to a galaxy, even to the Milky Way itself, then, going one step further, with a faith that laughs at scientific data and leaps beyond the narrow bounds of pure reasoning, we affirm that there must even be a centre of gravity to the entire Universe. Now let me ask the reader, What can be more fitting, more appropriate, more reasonable than to infer that the centre of gravity of the Universe is to be found in that celestial orb or orbs where the throne of God exists and endures, and where ultimately there will be congregated together in perfect felicity the spirits of just men made perfect, not only from our insignificant planet, but all the spirits of all beings from all the planets which in their almost infinite number are circled round their central suns by the electro-magnetic Aether? It is there, in these bright orbs, with their vision and powers spiritualized, quickened and intensified, that all perfected spirits shall look out into space, with increasing wonder, upon the birth and decay of worlds, the evolution and devolution of planets and systems and constellations, and shall watch the continuation and working out of that grand and glorious plan, which alone finds its perfection and its ultimate fulfilment in the wisdom, and power, and glory of the Eternal Spirit of the Living God.
