"You bewilder me," said Mercy. "I cannot follow you. I am not fit for such high things!" "I will go on; you will soon begin to see what I mean: I know what you are fit for better than you do yourself, Miss Mercy.--Think then how it would be if this blue sky were plainly a solid. Men of old believed it a succession of hollow spheres, one outside the other; it is hardly a wonder they should have had little gods. No matter how high the vault of the inclosing sphere; limited at all it could not declare the glory of God, it could only show his handiwork. In our day it is a sphere only to the eyes; it is a foreshortening of infinitude that it may enter our sight; there is no imagining of a limit to it; it is a sphere only in this, that in no one direction can we come nearer to its circumference than in another. This infinitive sphere, I say then, or, if you like it better, this spheric infinitude, is the only figure, image, emblem, symbol, fit to begin us to know God; it is an idea incomprehensible; we can only believe in it. In like manner God cannot by searching be found out, cannot be grasped by any mind, yet is ever before us, the one we can best know, the one we must know, the one we cannot help knowing; for his end in giving us being is that his humblest creature should at length possess himself, and be possessed by him." "I think I begin," said Mercy--and said no more. "If it were not for the outside world," resumed Ian, "we should have no inside world to understand things by. Least of all could we understand God without these millions of sights and sounds and scents and motions, weaving their endless harmonies. They come out from his heart to let us know a little of what is in it!" Alister had been listening hard. He could not originate such things, but he could understand them; and his delight in them proved them his own, although his brother had sunk the shaft that laid open their lode. "I never heard you put a thing better, Ian!" he said. "You gentlemen," said Mercy, "seem to have a place to think in that I don't know how to get into! Could you not open your church-door a little wider to let me in? There must be room for more than two!" She was looking up at Alister, not so much afraid of him; Ian was to her hardly of this world. In her eyes Alister saw something that seemed to reflect the starlight; but it might have been a luminous haze about the waking stars of her soul! "My brother has always been janitor to me," replied Alister; "I do not know how to open any door. But here no door needs to be opened; you have just to step straight into the temple of nature, among all the good people worshipping." "There! that is what I was afraid of!" cried Mercy: "you are pantheists!" "Bless my soul, Mercy!" exclaimed Christina; "what do you mean?"
