Luke 11:51Meaning & Commentary from the Church Fathers

The Lord also discloses that the Jews are descendants of Cain, inheritors of his sinful nature, indicating that all the blood shed from Abel to Zechariah will be demanded from this generation. He states, "You killed the prophets, your brothers," echoing the way Abel was slain. This connection is not unfounded, as some have viewed Cain as emblematic of those who persecuted the prophets, leading to their punishment sevenfold. In contrast, Lamech is seen as a symbol of those who took Christ's life, incurring a retribution of seventy times seven, resulting in their dispersion into a state of irreversible exile.

“From the blood of Abel, the just, to the blood of Zacharias,” He states, “not only up to that moment but even until this day.” As He stood among them, He did not demand retribution for His own blood until after they had put Him to death, so that they could not claim it was preordained. He thus pronounced judgment upon them for the righteous ones slain previously, aiming to dissuade them from killing more and granting them a chance to repent of His death, which the law did not permit for those responsible for slaying the prophets. The law declares, “Whosoever kills, let him die” (cf. Matt. 5:38), and does not say, “If he does not repent first, then it shall be forgiven him.” However, the Lord allowed them the opportunity to repent for His murder if they chose to do so.

The superficial devotion of the Jews is strikingly illustrated here. By constructing the tombs of the prophets, they criticize their forebears, yet in replicating their ancestors' wrongdoings, they ultimately condemn themselves. In honoring the sepulchers of the prophets, they condemn the sins of the murderers, revealing themselves to be true successors of their forefathers' wickedness. The transgression lies not in the act of building tombs, but in the replication of sinful actions. Those who have committed graver sins cannot escape the legacy of their ancestral transgressions; by crucifying the Son of God, they have only compounded the weight of their fathers' wrongs.

Utilizing the imagery of prophecy, He reveals what is to come: Let the blood of all the prophets, spilled since the world's foundation, from the blood of Abel to that of Zechariah, who was murdered between the altar and the temple, be demanded from this generation. This is stated clearly. To you, I declare that this will be accounted for by this generation. Also this.

The Lord acknowledged that the actions of the legal experts were just as unlawful as those who aligned with them. He criticized the harshness with which they enforced regulations while failing to obey them themselves, as well as the pride with which they decorated the graves of the prophets, their forebears in teaching. In truth, given their inner malice directed against Jesus and His followers, it would be more accurate to perceive them as the heirs of those false prophets and wicked individuals who had once murdered the prophets. Ultimately, He warned them of divine retribution for seizing the keys to understanding God's Word, for they neither utilized it as a genuine guide to the Kingdom of God nor facilitated others in finding their way through it.

In these acts of violence, there was a defiance against God’s intent, and for this, the blood of all the prophets, shed from the beginning of time, from Abel to Zechariah, who was slain between the altar and the temple, will be required from this generation. Some scholars suggest that this refers to Zechariah son of Jehoiada, who was stoned in the temple court during the reign of Joash (2 Chronicles 24:20-21), yet this interpretation seems inadequate, as numerous prophets were killed after him. Christ refers instead to Zechariah son of Barachiah as the last of the prophets to suffer martyrdom.

Alas for those who feign repentance while they condemn their forebears for persecuting the prophets, for they harbor within themselves the same murderous spirit as their ancestors. In fact, they exceed the wickedness of their predecessors by committing even greater atrocities. Upon this generation shall come the full weight of all the righteous blood shed on the earth, from the blood of righteous Abel to that of Zacharias, whom they murdered between the temple and the altar. The tempest of divine judgment was already ominously assembling, poised to unleash its fury upon their guilty heads.

A certain legal expert, who heard the teachings of the Lord, felt a sense of offense. He was part of a group that, through their study of the law, believed themselves to be more virtuous and righteous than the Pharisees criticized by the Savior. The lawyer addressed Jesus Christ, saying, "Teacher, your words disturb us. The lawyers, who burden the hearts of people with trivial and arbitrary human regulations, are hypocritical heirs who honor the memory of their ancestors. They build monuments for the prophets who were once slain, yet their thoughts mirror those of the murderers. These destroyers of their own nation have seized the key to understanding, using it solely to shut even tighter the door to salvation; they stand under the rigorous judgment of God's righteousness.
