He First Found His Own Brother: John 1 for Fathers

What the Text Says

John opens his Gospel differently than the other three. There is no genealogy, no census, no stable. Instead: “In the beginning was the Word, and the Word was with God, and the Word was God” (Jn 1:1). Everything that exists was made through him, and “in him was life, and the life was the light of men” (Jn 1:3-4). John the Baptist is introduced not as the light itself but as a witness sent to testify to it, “that all might believe through him” (Jn 1:6-8). Then comes the center of the whole prologue: “And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory” (Jn 1:14). To all who receive him and believe in his name, “he gave power to become children of God” (Jn 1:12).

When priests and Levites from Jerusalem question John the Baptist about his identity, he flatly denies being the Christ, Elijah, or “the prophet,” and identifies himself instead as “the voice of one crying in the wilderness” preparing the Lord’s way, exactly as Isaiah foretold (Jn 1:19-23). The next day, John sees Jesus approaching and declares, “Behold, the Lamb of God, who takes away the sin of the world!” (Jn 1:29). He testifies that he saw the Spirit descend on Jesus like a dove and remain, confirming this is “the Son of God” (Jn 1:32-34).

The following day, two of John’s own disciples hear him again point to Jesus, “Behold, the Lamb of God!” and they leave John to follow Jesus instead (Jn 1:35-37). Jesus turns and asks what they are seeking, and invites them, “Come and see” (Jn 1:38-39). One of the two is Andrew, and the very first thing Andrew does is go find his own brother, Simon, and tell him, “We have found the Messiah.” He brings Simon directly to Jesus, who renames him Cephas, Peter (Jn 1:40-42). The next day, Jesus calls Philip, who then finds Nathanael and tells him about Jesus of Nazareth. Nathanael is skeptical, “Can anything good come out of Nazareth?” but Philip simply answers, “Come and see” (Jn 1:43-46). When Nathanael meets Jesus, Jesus tells him he saw him under the fig tree before Philip ever called him, and Nathanael immediately confesses, “Rabbi, you are the Son of God! You are the King of Israel!” (Jn 1:47-49).

What the Church Teaches

“The Word became flesh” is the Church’s foundational statement of the Incarnation, and it is treated as a genuine mystery of the faith, not a metaphor. CCC 456-460 teaches that the Son of God truly took on human flesh so that we might know God’s love, be reconciled with him, and be made partakers of the divine nature. CCC 423 states plainly that “we believe and confess that Jesus of Nazareth… is the eternal Son of God made man.”

Becoming a “child of God” through faith and Baptism is not a figure of speech. It is a real, ontological change the Church calls adoptive sonship. CCC 1996-1997 teaches that grace makes us “partakers of the divine nature” and adopted sons of the Father, in and through the only Son, drawing directly on John 1:12.

John the Baptist’s identity is defined entirely by pointing away from himself and toward Christ. CCC 719 teaches that John is the last of the prophets, whose whole role is to “‘prepare the way of the Lord’” by proclaiming him already present.

“The Lamb of God, who takes away the sin of the world” (Jn 1:29) is the very title the Church places in the mouth of every priest at every Mass just before Communion, underscoring that this is not a one-time historical announcement but a present reality proclaimed at every liturgy.

Jesus’ invitation, “Come and see,” and his personal knowledge of Nathanael before they ever met, reflect the Church’s teaching that God’s call is always personal and precedes our own search for him. CCC 1 teaches that God, “infinitely perfect and blessed in himself,” calls man to share in his own blessed life out of pure goodness, not because we sought him out first.

Personal Reflection: For Fathers

(This section is personal reflection and pastoral application, not a restatement of defined Church teaching. If you have a real question about how to bring faith into your household, bring it to confession or a conversation with a priest or trusted mentor rather than treating this reflection as a ruling.)

Andrew’s first move after meeting Jesus is not to sit with the experience privately. “He first found his brother Simon” (Jn 1:41). Before Andrew does anything else recorded in the Gospels, he goes and gets his own family member and brings him to Christ. That single verse is a job description for fatherhood. The first evangelization most of your children and your wife will ever receive is not going to come from a parish program. It is going to come from you finding them, the way Andrew found Simon, and simply saying, in whatever words fit you, “We have found the Messiah, come see.”

Notice also that Andrew does not argue Simon into faith. He brings him directly to Jesus and lets Jesus do the rest, the same way Philip answers Nathanael’s skepticism, “Can anything good come out of Nazareth?” not with a debate but with “Come and see.” A father does not have to have every theological answer prepared before he leads his family toward Christ. He has to actually bring them, consistently, and let the encounter itself do the deeper work.

There is something else worth noticing in how Jesus meets Nathanael: he already knew him, “under the fig tree,” before Philip ever said a word. Whatever your children have not yet said out loud to you, whatever private struggle is happening under the surface in your home, Christ already sees it fully and still calls that person to himself. That should shape how you lead: not waiting for your family to have it all figured out before bringing them to him, but bringing them as they actually are, the way Andrew brought Simon and Philip brought Nathanael, trusting Christ to do what only he can do.

Call to Action

This week, be an Andrew in your own household. Find one specific person in your family and say some version of, “I want you to come with me and see this,” whether that means Mass, a rosary, a real conversation about faith, or simply praying together out loud for the first time in a while.
