Matthew 20:12

But it can be asked how those who are called to the kingdom even at a late hour are said to have murmured. For no one who murmurs receives the kingdom of heaven, and no one who receives it can murmur. But because the ancient fathers, up until the coming of the Lord, no matter how justly they had lived, were not led to the kingdom unless He descended who would open the gates of paradise to men by the interposition of His death, their murmuring was this very thing: that they both lived rightly for the sake of receiving the kingdom, and yet were long delayed in receiving the kingdom. For those whom the places of hell, however tranquil, received after their righteousness was completed, for them indeed it was both to have labored in the vineyard and to have murmured. Therefore they receive the denarius as if after murmuring, who after long periods in hell arrived at the joys of the kingdom. But we who come at the eleventh hour do not murmur after our labor and receive the denarius, because after the coming of the Mediator, coming into this world, we are led to the kingdom as soon as we depart from the body, and we receive without delay what the ancient fathers deserved to receive with great delay.

There is also another question. What does it mean that he says, who have borne the burden of the day and the heat? Because they did not bear more than the time they lived, and modern people likewise. What, then, is meant? A threefold answer …

Thou hast made them equal to us - So St. Peter expressly, Acts xv, 9. God-hath put no difference between us (Jews) and them, (Gentiles, ) purifying their hearts by faith.

The Gentiles, who are newly called in, have as much of the privileges of the kingdom of the Messiah as the Jews have, who have so long been labouring in the vineyard of the Old-Testament church, under the yoke of the ceremonial law, in expectation of that kingdom.

Saying, these last have wrought but one hour,.... Thinking it hard, that they should have the same reward for the service of one hour, others had for the service of many.

There are undeniable difficulties in the parable contained in these verses. The key to the right explanation of them must be sought in the passage which concludes the last chapter. There we find the apostle Peter asking our Lord a remarkable question: “We have forsaken all and followed thee! What shall we have therefore?” There we find Jesus giving a remarkable answer. He makes a special promise to Peter and his fellow disciples: they should one day sit on twelve thrones, judging the twelve tribes of Israel.

He makes a special promise to Peter and his fellow disciples: they should one day sit on twelve thrones, judging the twelve tribes of Israel.He makes a general promise to all who suffer loss for his sake: they “should receive a hundred fold and inherit everlasting life.” Now we must bear in mind that Peter was a Jew, and like most Jews he had probably been brought up in much ignorance as to God’s purposes respecting the salvation of the Gentiles. In fact we know from the Acts that it required a vision from heaven to take that ignorance away ( Acts 10:28 ). Furthermore, we must bear in mind that Peter and his fellow-disciples were weak in faith and knowledge. They were probably apt to attach a great importance to their own sacrifices for Christ’s sake, and inclined to self-righteousness and self conceit. Both these points our Lord knew well. He therefore speaks this parable for the special benefit of Peter and his companions. He read their hearts. He saw what spiritual medicine those hearts required, and supplied it without delay. In a word, he checked their rising pride, and taught them humility. In expounding this parable, we need not inquire closely into the meaning of the “penny,” the “marketplace,” the “steward” or the “hours.” Such inquiries often darken counsel by words without knowledge. Well says a great divine, “the theology of parables is not argumentative.” The hint of Chrysostom deserves notice.

The burden and heat of the day - The burden means the heavy labor, the severe toil. We have continued at that toil in the heat of the day. The others had worked only a little while, and that in the cool of the evening, and when it was fax more pleasant and much less fatiguing.
