Mark 3:17Meaning & Commentary from the Church Fathers

He referred to those accompanying Jacob as ‘sons of thunder.’ What was the reason behind this? It serves to illustrate that He is the One who bestowed the Scriptures of the Old Testament and who altered names within it: calling Abram to be Abraham (Gen. 17:5), Sarah to be Sarah (Gen. 17:15), and Jacob to become Israel (Gen. 32:28). Furthermore, there existed a practice in ancient times of assigning names to reflect significant experiences, as seen with Leah (Gen. 29:32; Gen. 30:11, 13, 18, 20). There was purpose in this tradition; the name itself was meant to act as a reminder of God's grace, allowing the prophetic significance of these names to continually inspire those who heard them.

The Evangelist names the apostles in contrast to the false apostles, enabling the identification of the authentic ones. He refers to the sons of Zebedee as the sons of thunder, highlighting their remarkable abilities as preachers and theologians.

Thunder arises when the powerful and arid winds, trapped within the cavities of clouds and swirling under tension, strive to break free. The intensely pressurized clouds resist this force, generating a sharp sound as the winds collide with them. However, when the winds become too much for the clouds to contain, much like overinflated bubbles, they begin to unleash their force, resulting in resounding thunder as the winds escape. This phenomenon often accompanies lightning. In a similar way, the Lord who is present over the waters (cf. Ps. 28:3) creates mighty thunderous sounds, producing a remarkable noise through the gentle movement of the air (cf. Is. 29:6).

He named him Boanerges, which translates to son of thunder. Some suggest that thunder arises from dense air trapped in clouds, leading to the creation of lightning through friction or thunder through an explosive release. To suggest that thunder originates from thunder itself is understandable, for the parent and offspring share qualities. Consequently, as a reflection of the Holy Spirit, the Apostle is referred to as the son of thunder, for he both illuminates and reverberates as he declares sacred truths, seemingly bursting forth from the clouds of divine favor. Let us consider, if we may, the nature of his thunderous declarations, that we might be more astonished by the strength of the One who bestowed this name upon him.

John, known as the ‘Son of Thunder,’ was elevated to heaven by Christ and became a voice through whom He proclaimed His message. Among others, he uniquely bore the title ‘Son of Thunder’ and thus engaged in more fervent preaching. He elucidated the events surrounding the resurrection of our Lord and described the nature of His appearances following the Resurrection.

James and John, known as "Sons of Thunder," serve as powerful proclaimers of the Gospel.

In this context, "thunder" refers to the proclamation of the gospel. Just as the sound of thunder embodies a divine resonance that far exceeds any human utterance, the gospel message, with its divine origin, carries extraordinary strength. It is not born of human desire but is instead empowered by God, permeating the entirety of creation.

Following the account of the second-first Sabbath and the one that succeeded it, Luke does not suggest any notable alteration in the location of Christ's ministry. However, according to the Gospel of Mark, the first event that follows is the selection of the twelve apostles. The Gospel of Matthew does not recount this event; instead, it presents the names of the apostles when they were commissioned for preaching, as though their selection had been previously announced. Neither Mark, who notes that Jesus ascended the mountain, nor Luke, who refers to "the days," links this event chronologically to the prior one. Luke recounts that the Lord dedicated the entire night before this event to prayer.

Jesus designated James and John, the sons of Zebedee, as the sons of thunder, which highlighted their bold and passionate nature. They demonstrated these characteristics when they sought Jesus's approval to call down fire from heaven on those who rejected Him in a Samaritan village (Luke 9:54).

The other two selected disciples, James and John, the sons of Zebedee, exhibited distinctive traits. They compensated for Peter's shortcomings. Known for their eagerness to embrace new teachings and passionately incorporate them into their lives, they demonstrated a profound loyalty to their Master akin to Peter's, despite sometimes sliding into extreme views, particularly in their desire for their Lord's dominion.

"Voanerges, translating to sons of thunder" refers to the Aramaic pronunciation and the meaning in Syriac. This metaphor suggests that James and John, the sons of Zebedee, embody qualities similar to thunder in various ways. This title highlights the distinctive traits of the Zebedee brothers, much like the name Peter reflects aspects of Simon's nature. The unique characteristics attributed to the sons of Zebedee—power, impulsiveness, and a certain dignity—were clearly demonstrated when they once requested the Lord to call down fire from heaven upon a hostile Samaritan village, akin to Elijah (Luke 9:54). This nickname appears only in this context and is not found elsewhere in scripture, indicating that it did not become a commonly used name for them like Peter or Cephas did for Simon.
