And here, by way of parenthesis, we may stop to explain the force of that expression, so common in Scripture, '_Thou hast said it._' It is an answer often adopted by our Saviour; and the meaning we hold to be this: Many forms in eastern idioms, as well as in the Greek occasionally, though meant _interrogatively_, are of a nature to convey a direct categorical _affirmation_, unless as their meaning is modified by the cadence and intonation. _Art thou_, detached from this vocal and accentual modification, is equivalent to _thou art_. Nay, even apart from this accident, the popular belief authorized the notion, that simply to have uttered any great thesis, though unconsciously--simply to have united verbally any two great ideas, though for a purpose the most different or even opposite, had the mysterious power of realizing them in act. An exclamation, though in the purest spirit of sport, to a boy, '_You shall be our imperator_,' was many times supposed to be the forerunner and fatal mandate for the boy's elevation. Such words executed themselves. To connect, though but for denial or for mockery, the ideas of Jesus and the Messiah, furnished an augury that eventually they would be found to coincide, and to have their coincidence admitted. It was an _argumentum ad hominem_, and drawn from a popular faith. But a modern reader will object the want of an accompanying design or serious meaning on the part of him who utters the words--he never meant his words to be taken seriously--nay, his purpose was the very opposite. True: and precisely that is the reason why his words are likely to operate effectually, and why they should be feared. Here lies the critical point which most of all distinguishes this faith. Words took effect, not merely in default of a serious use, but exactly in consequence of that default. It was the chance word, the stray word, the word uttered in jest, or in trifling, or in scorn, or unconsciously, which took effect; whilst ten thousand words, uttered with purpose and deliberation, were sure to prove inert. One case will illustrate this:--Alexander of Macedon, in the outset of his great expedition, consulted the oracle at Delphi. For the sake of his army, had he been even without personal faith, he desired to have his enterprise consecrated. No persuasions, however, would move the priestess to enter upon her painful and agitating duties for the sake of obtaining the regular answer of the god. Wearied with this, Alexander seized the great lady by the arm, and using as much violence as was becoming to the two characters--of a great prince acting and a great priestess suffering--he pushed her gently backwards to the tripod on which, in her professional character, she was to seat herself. Upon this, in the hurry and excitement of the moment, the priestess exclaimed, _O pai, anixaitos ei--O son, thou art irresistible_; never adverting for an instant to his martial purposes, but simply to his personal importunities.
