But I pass by all that, and ask you to think how much lies in these words of our Lord: 'I am not come to destroy, but to fulfil.' They imply a claim that His life was a complete embodiment of God's law. Here is a man beginning His ministry as a religious teacher, with the assertion, stupendous, and, upon any other lips but His, insane arrogance, that He had come to do everything which God demanded, and to set forth before the world a living Pattern of the whole obedience of a human nature to the whole law of God. Who is He that said that? And how do we account for the fact that nineteen centuries have passed, and, excepting in the case of here and there a bitter foe whose hostility had robbed him of his common sense, no lip has ventured to say that He claimed too much for Himself when He said, 'I am come to fulfil the law'; or that He falsely read the facts of His own experience and consciousness when He declared, 'I have finished the work which Thou gavest Me to do.'
Still further, here our Lord claims specifically and expressly to fulfil not only law but prophets. That is to say, He sets Himself forth as the Reality which had filled the imaginations and the hearts of a whole nation for centuries; as the living Reality which had been meant by all those lofty words of seers and prophets in the past. He declares that all those rapturous forecastings, all those dim anticipations, all those triumphant promises, were not left to swing _in vacuo_, or to float about unfulfilled, but that He stood there, the actual Realisation of them all; and in Him, wrapped up as in a seed, the Kingdom of Heaven was among men.
And still further, He claims not only personal purity and completeness, and the fulfilment of all prior and prophetic anticipation, but also He claims to have, and He exercises, the power of moulding, expanding, interpreting, and in some cases brushing aside, laws which He and they alike knew to be the laws of God. I do not need to specify in detail the instances which are contained in this Sermon on the Mount. But I simply ask you to consider the formula with which our Lord introduces each of His references to that subject. 'Ye have heard that it hath been said to them of old time' so-and-so,--and then follows a command of the Mosaic law; but '_I_ say unto you' so-and-so,--and then follows a deepening or a modification or a repeal, of statutes acknowledged by Him and His hearers to be divine. He certainly claims to speak with the same right and authority as the old Law did. He as certainly claims to speak with incomparably higher authority than Moses did, for the latter never professed to give precepts of his own. He was not the Lawgiver, as he is often called, but only the messenger of the Lawgiver. But Christ is Himself the fountain of the laws of His Kingdom. Nor only so, but He puts Himself without apology or explanation in front of Moses and asserts power to modify, to set aside, or to re-enact with new stringency, the precepts of the divine law.
One supposition alone accounts for Christ's attitude to law and prophets in this Sermon, and that is that the Eternal Wisdom and Personal Word of God, which at sundry times and in 'divers manners' spake to the old world by Moses, itself at last, in human form and personal guise, came here on earth and spake to us men. It is the same Voice that breathed through the prophets of old, and that spake on the lips of the Christ of Nazareth; the same Eternal Word who manifested Himself in a 'fiery law' on Sinai, and in words of no less majesty and of deepened gentleness, when He gathered the people round about Him, and said to them, 'It hath been said to them of old time, ... but _I_ say unto you ...'
