Luke 5:4Meaning & Commentary from the Church Fathers

He instructs that the net be cast out. Words without action lack evidence, so it is fitting that the spoken word be followed by tangible results: by divine command you will capture that which has eluded you and acquire what is absent.

While Simon pondered these thoughts, the Lord concluded His teaching to perform a miracle and persuade Simon. It can be challenging to convince a simple man solely through words.

And since He taught from the boat, the owner was rewarded for his efforts. In fact, He blessed him abundantly, providing him with a great catch of fish and inviting him to become His follower. Consider the wonder of the Lord, as He draws each individual through unique means that resonate with their own experiences; for instance, the wise men were guided by a star, while the fishermen were called through their catch. Note as well the humility of Christ in asking Peter to leave the shore; He 'begged' rather than 'entreated,' highlighting Peter's remarkable obedience as he welcomed this unknown Man into his vessel and followed His instructions without hesitation.

Having imparted sufficient teaching, and with a small miracle to enhance His message for the onlookers, He instructed Simon and his fellow disciples to cast off from the land and lower the net to gather fish from the waters.

Where love is perfected, there is peace (cf. 1 Jn. 4:18). While others are instructed to cast their nets, Peter receives the directive to “Swim to the deep,” which implies a deep exploration of understanding. What greater depth exists than to perceive the profound wealth of God’s wisdom (cf. Rom. 11:33), to know the Son of God, and to proclaim His divine incarnation? Though human reason cannot fully grasp this mystery, the abundance of faith can embrace it. I may not comprehend the manner of His incarnation, yet it is undeniable that He has come into being. Although I may lack insight into the details of His nativity, I affirm the truth of His existence.

He took a seat in the boat and began to teach the crowd. By teaching from the boat, He ensured that the throng would not press in on Him, allowing Him to see everyone standing on the shore. This method is reiterated in the account found in Matthew at the conclusion of chapter twenty-three. When He finished His teaching, He turned to Simon and instructed him, "Launch out into the deep and let down your nets for a catch." Aware that they had labored all night without success, He commanded them to cast their nets once more, so that through this action, they might deepen their understanding of His power, strengthen their faith in Him, and ultimately abandon their fishing pursuits to follow Him consistently.

If, however, you go out with Christ to where it is deep, then fear nothing, but go with Him joyfully and with good courage. You will make the best catch, and you will fill both the material and the spiritual boat. You will catch the best fish, O you faithful, and you will surely reach the shore, the shore of the Kingdom of Christ.

Having fulfilled the spiritual mission, He also attended to the needs of the body. He instructed Peter to "Go into the deep," meaning to navigate the vessel into the deeper part of the lake. Additionally, He directed Peter and his companions to "Cast your nets into the deep," urging them to spread their nets for a catch. This illustration serves as a reminder and encouragement for you, Christian, that you should prioritize the work of God above your earthly pleasures, ensuring that you first accomplish the divine tasks and then attend to your physical needs. In answer to the Lord's command, Peter expressed the following:

Jesus chose to have some of his disciples as his constant associates to serve as witnesses to all he did. By observing the entirety of his life and ministry, they would better understand his deep intentions, gain a clearer insight into the kingdom of the Messiah, and subsequently declare his teachings with greater assurance. At that moment, this purpose was partly realized. After addressing the crowds, Jesus turned to Simon and inquired about the fishing during his absence. Jesus was aware that their efforts had yielded no catch, and their nets were empty, yet he wanted to highlight this fact to his disciple. He aimed to demonstrate that without him, they could not attain success even in their usual endeavors. He sought to reassure them that their anxieties about abandoning familial responsibilities in order to follow him were unfounded, and that any apparent losses would be abundantly compensated by his word alone.

After He concluded His sermon, His thoughts were not on His own fatigue but rather on His struggling disciples. He recognized that their efforts had yielded no results and that they had caught no fish. However, He observed that as He spoke, they were diligently engaged in their tasks while simultaneously absorbing His teachings and preparing for a forthcoming endeavor that promised greater rewards. To uplift their spirits, He instructed Peter to venture into deeper waters and cast his nets once more. Although Peter felt downcast, a simple command from the one he revered deeply, whose power he had witnessed time and again, was sufficient to inspire him. His faith was soon rewarded; as he cast his nets, they became filled with an abundance of fish. The excitement among the disciples grew as Simon and Andrew signaled to Zebedee and his sons, along with their workers, to come in their boat to assist with drawing in the remarkable catch that threatened to overwhelm the nets.

The typical fishing nets were designed in such a way that fishing in deeper waters was impractical, as a different technique was required for that. Thus, fish were generally caught near the shore in shallow areas. This made Peter marvel at the Lord's command even more, making the miracle particularly remarkable. Having previously witnessed many extraordinary deeds of the Lord and hearing of even more, Peter did not oppose Him. Instead, after expressing that they had toiled all night without success—an aspect that intensified the nature of the ensuing miracle—he responded with faith to the Lord's directive. As a result, the miraculous event unfolded, and they netted “a great multitude” of fish.

The initial act of Christ the Savior in Capernaum was to summon Simon, Andrew, and the sons of Zebedee to be His disciples. While the Lord walked along the lake's shore, He observed two boats on the water, with the fishermen having come ashore—some were washing their nets, and others were mending them. One of the boats belonged to Simon and Andrew, while the other, slightly farther away, belonged to Zebedee, who was engaged in fishing alongside his workers and his sons, James and John. The crowds were drawn to the Lord, eager to hear His teachings, and He stepped into Simon's boat, requesting him to move away from the shore. From there, He instructed the gathered multitude.
