Elias is come already. — These words, the emphatic repetition of what had been said before in Matthew 11:14 (see Note there), ought, it is believed, to be decisive as to the issue raised in the preceding verse. So far as the prophecy of Malachi required the coming of Elijah, that prophecy had been fulfilled in the Baptist, all unconscious of it as he was, as coming in the spirit and power of Elijah (Luke 1:17). The disciples need not look for any other personal appearance. The use of the present and future tenses in Matthew 17:11 point to a deeper truth, which they were to learn afterwards. The Elijah ministry, the work of the preacher of repentance, is not a transient phenomenon belonging to one stage only of the Church’s history, but was to be, throughout the ages, on to the end of all things, the indispensable preparation for the coming of the Lord. Only through it could all things be restored, and the path made ready for the heralds of forgiveness and of peace.
They knew him not. — The Greek word implies full and accurate knowledge. Better, perhaps, they recognised him not. Must we not say that those who, after these words, still look forward to the personal advent of Elijah are unconsciously placing themselves on a level with those whose dimness of perception our Lord thus condemns?
But have done unto him whatsoever they listed. — Literally, they did in him (in him, i.e., as the region in which their will wrought) whatsoever they would. To “list,” now practically archaic, was the same as “lust,” without the special evil sense which has attached to the latter word. It is significant that our Lord charges the guilt of the rejection and death of John upon the scribes and the people at large, with no special reference to the Tetrarch Antipas. The passions and intrigues of the palace were but instruments working out the intent of the Pharisees and Sadducees.
Likewise shall also the Son of man suffer of them. — Another instance of what may be called the new colour which from the time of the Transfiguration spreads over our Lord’s teaching. All is, in one aspect, darker, sadder, more sombre. He is drawing nearer to the cross, and He brings the thought of the cross closer to the minds of the disciples.
