About this session
Theme: Jesus Christ: God Becomes Man
Time: 6:00 PM - 8:00 PM
At the heart of the Gospel, the Good News, is not first an idea or a moral program, but a Person: Jesus Christ. This session asks the central Christian question: Who is Jesus? Catholics believe and proclaim that Jesus is not only a great teacher, prophet, healer, or religious leader. He is the eternal Son of God who truly became man for our salvation.
The Church teaches this because it is what Scripture reveals and what the first Christians confessed after encountering Jesus, especially in his death and Resurrection. If Jesus is truly God and truly man, then he reveals God fully, joins himself to our human life, saves us from sin and death, and calls us to follow him with our whole lives.
The teaching, section by section
The Gospel begins with Jesus himself
The word Gospel means “Good News.” The Good News is that God has acted to save us, and he has done so by sending his Son. Christianity is therefore not mainly about admiring religious values from a distance. It is about meeting Jesus Christ, trusting him, and learning to live in communion with him.
Many people begin by respecting Jesus. They may admire his compassion, his courage, his teaching on love, or his care for the poor. That is a good beginning, but the Church invites us to go further. Jesus does not simply point toward God as a helpful teacher might. He reveals God because he is God the Son.
The session raises a question that every disciple must face: if Jesus is truly Lord, what changes? Faith in Jesus is not only agreement with a doctrine. It becomes a relationship of trust, worship, repentance, and love.
Key truth: The Gospel is the Good News that God has come to us in Jesus Christ, his Son.
The Word became flesh
The Incarnation is the mystery that the eternal Son of God became a real human being in Jesus Christ. “Incarnation” means “taking on flesh.” The Son did not stop being God; he took on our humanity. Jesus is one divine Person with two natures: a divine nature and a human nature. A nature answers “what someone is”; a person answers “who someone is.” Jesus is the divine Son, truly God and truly man.
This is why Catholics call Mary the Mother of God: not because she existed before God, but because the child she bore is truly the divine Son made man. Jesus was conceived by the Holy Spirit and born of Mary. He entered human life from the inside: birth, growth, hunger, work, friendship, sorrow, suffering, and death. Yet he remained without sin.
The Church also speaks of Jesus as the Second Person of the Trinity. The Trinity is the mystery that there is one God in three divine Persons: Father, Son, and Holy Spirit. The Son becomes man so that we can know the Father, be freed from sin, and be brought into God’s own life.
Key truth: In the Incarnation, the Son of God truly becomes human without ceasing to be God.
Jesus cannot be only a good teacher
The materials for this session name a common modern view: Jesus was a wise moral teacher, but not God. The difficulty is that Jesus’ own words and actions do not fit comfortably into that category. He forgives sins, speaks with divine authority, calls people to follow him above all else, and receives the confession of faith that belongs to God.
The title Messiah means the “Anointed One,” the promised king and savior expected by Israel. Peter’s confession that Jesus is the Messiah and the Son of the living God is not a small compliment. It is a recognition, given by grace, that Jesus is the one in whom God’s promises are fulfilled.
Jesus’ miracles are also signs of who he is. They are acts of mercy, but they are more than acts of kindness. They reveal authority over sickness, creation, sin, and death. His Resurrection confirms that he is not simply one more teacher among many, but the living Lord.
Key truth: Jesus’ words, works, death, and Resurrection press us to answer personally: “Who do you say that I am?”
The Kingdom Jesus announces
Jesus begins his public preaching by announcing that God’s Kingdom has drawn near. The Kingdom of God or Kingdom of Heaven means God’s reign: his saving presence, power, justice, mercy, and peace breaking into the world through Jesus. It is not simply a political territory. It begins wherever God is received, obeyed, and loved.
To enter this Kingdom, Jesus calls people to repent and believe. Repentance means turning away from sin and turning toward God. Belief is not only accepting facts; it is entrusting oneself to God. The Kingdom asks for a changed heart.
Jesus teaches that the heart of God’s law is love: love of God and love of neighbor. Commandments are God’s instructions for living in right relationship with him and with others. They are not arbitrary rules; they show us the path of life. Christian love is not merely a feeling. It means willing and seeking the true good of another person.
Key truth: Jesus announces that God’s reign has come near and invites us to enter it through repentance, faith, and love.
Mercy, humility, and the shape of discipleship
Two marks of the Kingdom emphasized in this lesson are mercy and humility. Mercy is God’s compassionate love that forgives, heals, and welcomes sinners home. To receive mercy is to admit that we need saving. To give mercy is to let God’s forgiveness reshape the way we treat others.
Humility is the virtue of knowing the truth about ourselves before God. It is not self-hatred or pretending we have no gifts. It is knowing that everything good comes from God and that we depend on him. The humble person can receive grace because he or she is not trying to be self-sufficient.
Jesus himself is the model of both mercy and humility. Though he is Lord, he comes as a servant. The crucifix, the cross with the body of Christ on it, keeps this truth before our eyes. Catholics do not display the crucifix because suffering is the end of the story, but because on the Cross we see how far divine love goes. The crucifix says: this is what God’s mercy cost, and this is how deeply you are loved.
Key truth: To follow Jesus is to receive his mercy, learn his humility, and allow his love to change the way we live.
Saying yes to Jesus as Lord
St. Augustine’s story, included in the lesson materials, shows the difference between admiring Jesus from a distance and surrendering to him. Augustine was brilliant and restless. He searched for truth, success, pleasure, and meaning, but his heart remained unsettled until he gave himself to Christ. His famous words still speak to many seekers: “You have made us for yourself, and our hearts are restless until they find their rest in you.”
Following Jesus may require real change. It may touch how we pray, forgive, spend money, use our bodies, speak, work, and love our families. But the change is not loss for its own sake. It is the healing of our freedom. Jesus does not call us away from life; he calls us into life with God.
The question is not only “What do I think about Jesus?” but “Will I trust him?” The Christian answer grows over time, through prayer, Scripture, the sacraments, and the life of the Church.
Key truth: Jesus asks not only to be admired, but to be trusted, followed, and worshiped as Lord.

The saint of the day
On September 30 the Church celebrates Saint Jerome, Priest and Doctor of the Church. Jerome is especially remembered for his love of Scripture and for his work translating the Bible so that more people could hear the Word of God clearly.
His witness fits this session well: to know Christ, we must listen to the Scriptures that reveal him. Jerome reminds inquirers that study is not merely information-gathering; it can become a path of love for the Lord.
Taking it home
Questions to sit with
- Who is Jesus to me right now: teacher, healer, Lord, stranger, friend, God?
- What helps me believe that Jesus is truly God? What still feels difficult?
- How does it affect me to know that Jesus shared real human life?
- Where do I sense Jesus inviting me to repent, trust, or change?
- What would it mean for me to seek God’s Kingdom first in ordinary life?
- Is there someone toward whom I need to ask God for mercy or offer mercy?
- When I look at a crucifix, what do I see: guilt, love, suffering, hope, or something else?
This week’s invitation
- Read one of the Scripture passages listed above slowly and ask, “What does this show me about Jesus?”
- Pray the Jesus Prayer each day: “Lord Jesus Christ, Son of God, have mercy on me, a sinner.”
- Spend a few quiet minutes before a crucifix, at church or at home.
- Ask Jesus honestly: “Who are you calling me to become?”
- Talk with a trusted Catholic about what it means to call Jesus “Lord.”
- Practice one concrete act of mercy: forgive, apologize, listen, serve, or pray for someone difficult.
Closing prayer
Lord Jesus Christ, Son of God,
you are Emmanuel, God with us.
You became human without ceasing to be God,
and you came near to save us.
Open my mind to know who you are,
open my heart to trust your mercy,
and give me courage to follow you.
Teach me humility before your Cross,
and lead me into the Kingdom of the Father.
Lord Jesus Christ, Son of God,
have mercy on me, a sinner. Amen.
