20. Then he charged his disciples 1 not to tell any one that he was Jesus the Christ. 21. From that time Jesus began to make known to his disciples, that he must go to Jerusalem and suffer many things from the elders, and the chief priests, and the scribes, and be killed, and be raised again on the third day. 22. And Peter, taking him aside, 2 began to rebuke him, saying, Lord, spare thyself; 3 this shall not happen to thee. 23. But he turning said to Peter, Get thee behind me, Satan, thou art an offense to me; for thou relishest not those things which are of God, but those which are of men. 24. Then Jesus said to his disciples, If any man chooses to come after me, let him deny himself, and take up his cross, and follow me. 25. For whosoever would save his life shall lose it; and on the other hand, whosoever shall lose his life on my account shall find it. 26. For what doth it profit a man, if he shall gain the whole world, and lose his own soul? or what shall a man give, that, in exchange for it, he may redeem his soul? 27. For the Son of man will come in the glory of his Father with his angels: and then will he render to every one according to his actions. 28. Verily I say to you, There are some standing here, who will not taste death till they have seen the Son of man coming in his kingdom.
Having given a proof of his future glory, Christ reminds his disciples of what he must suffer, that they also may be prepared to bear the cross; for the time was at hand when they must enter into the contest, to which he knew them to be altogether unequal, if they had not been fortified by fresh courage. And first of all, it was necessary to inform them that Christ must commence his reign, not with gaudy display, not with the magnificence of riches, not with the loud applause of the world, but with an ignominious death. But nothing was harder than to rise superior to such an offense; particularly if we consider the opinion which they firmly entertained respecting their Master; for they imagined that he would procure for them earthly happiness. This unfounded expectation held them in suspense, and they eagerly looked forward to the hour when Christ would suddenly reveal the glory of his reign. So far were they from having ever adverted to the ignominy of the cross, that they considered it to be utterly unsuitable that he should be placed in any circumstances from which he did not receive honor. 4 To them it was a distressing occurrence that he should be rejected by the elders and the scribes, who held the government of the Church; and hence we may readily conclude that this admonition was highly necessary. But as the bare mention of the cross must, of necessity, have occasioned heavy distress to their weak minds, he presently heals the wound by saying, that on the third day he will rise again from the dead. And certainly, as there is nothing to be seen in the cross but the weakness of the flesh, till we come to his resurrection, in which the power of the Spirit shines brightly, our faith will find no encouragement or support. In like manner, all ministers of the Word, who desire that their preaching may be profitable, ought to be exceedingly careful that the glory of his resurrection should be always exhibited by them in connection with the ignominy of his death.
But we naturally wonder why Christ refuses to accept as witnesses the Apostles, whom he had already appointed to that office; for why were they sent but to be the heralds of that redemption which depended on the coming of Christ? The answer is not difficult, if we keep in mind the explanations which I have given on this subject: first, that they were not appointed teachers for the purpose of bearing full and certain testimony to Christ, but only to procure disciples for their Master; that is, to induce those who were too much the victims of sloth to become teachable and attentive; and; secondly, that their commission was temporary, for it ended when Christ himself began to preach. As the time of his death was now at hand, and as they were not yet fully prepared to testify their faith, but, on the contrary, were so weak in faith, that their confession of it would have exposed them to ridicule, the Lord enjoins them to remain silent till others shall have acknowledged him to be the conqueror of death, and till he shall have endued them with increased firmness.
