The Church is founded; but for a time it must remain in obscurity. The people are not ready; and the gospel, which is to be the power of God unto salvation, is not yet complete, until He shall go up to Jerusalem and suffer many things and die. Till then all that has passed in this sacred northern retreat must remain a secret: "He charged His disciples that they should tell no man that He was the Christ" (R.V.).
II.--THE CROSS (xvi. 21-28).
A still more searching test must now be applied. It is not enough to discover what they have learned from their intercourse with Him in the past; He must find out whether they have courage enough to face what is now impending in the future. Their faith in God as revealed in Christ His Son has been well approved. It remains to be seen whether it is strong enough to bear the ordeal of the cross, to which it must soon be subjected: "From that time forth began Jesus to show unto His disciples, how that He must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed."
Already from time to time He had darkly hinted what manner of death He should die; but it was only from this time that He began to _show_ it unto them, to put it before them so that they could not fail to see it. Herein see the wisdom and tender considerateness of "the Son of man." So dark and difficult a lesson would have been too much for them before. The ordeal would have been too severe. Not until their faith has begun with some firmness to grasp His true and proper divinity, can their hope live with such a prospect. There must be some basis for a faith in His rising again, before He can ask them even to look into the dark abyss of death into which He must descend. That basis is found in the confession of the rock-apostle; and relying on it He can trust them by-and-by, if not at once, to look through the darkness of the suffering and death to the rising again, the prospect of which He sets before them at the very same time: "and be raised again the third day." Besides, there was no possibility of their ever beginning to understand the atonement till they had grasped the truth of the incarnation. To this day the one is intelligible only in the light of the other. Those to whom Jesus of Nazareth is only "one of the prophets" cannot begin to see how He _must_ suffer and die. Only those who with the apostles rise to the realisation of His divine glory are prepared to understand anything of the mystery of His Cross and Passion.
As yet, however, the mystery is too deep and the prospect too dark even for them, as becomes painfully evident from the conduct of the bravest of them all, who "took Him, and began to rebuke Him, saying, Be it far from Thee, Lord: this shall not be unto Thee."
We naturally and properly blame the presumption of the apostle, who, when he did not understand, might at least have been silent, or have contented himself with some modest question, instead of this unbecoming remonstrance with One Whose Messiahship and Divine Sonship he had just confessed. But, though we may blame him for what he said, we cannot wonder at what he thought and felt. The lesson of the cross is just beginning. The disciples are just entering a higher form in the Master's school; and it does not follow, because they have undergone so well their examination on the great lesson of the past, that they are prepared all at once to take in what must be the great lesson of the future. They have had time for the first: may they not be allowed time for the second? Why, then, is Peter reproved so very severely?
