Luke 3 —

“Preparation, Repentance, and the Revelation of the Son”

Luke 2 closed with hidden growth.
Luke 3 opens with public awakening. The wilderness becomes the stage where God calls Israel — and ultimately the world — to readiness. John the Baptist prepares hearts, exposes false security, and announces the nearness of salvation. The chapter culminates in the baptism of Jesus, where divine identity is openly affirmed.

This chapter teaches one central truth:

Repentance prepares the heart for salvation, and Christ’s revealed identity inaugurates a new era in which humanity is invited into restored communion with God.

1. History Named: Salvation Anchored in Time

“In the fifteenth year of the reign of Tiberius Caesar…” (Lk 3:1)

Luke carefully situates events within political and religious history.

St Augustine writes:

“Redemption enters real history, not legend.”
(Sermons)

God’s work unfolds amid worldly power — yet transcends it.

Typology

Human authority provides backdrop; divine authority writes the story.

Salvation is historical and universal.

2. The Word in the Wilderness: John’s Calling

“The word of God came to John…” (3:2)

Not in the Temple or palace — but wilderness.

“The wilderness clears the noise that hides God’s voice.”

3. A Baptism of Repentance: Straightening the Path

Crowds ask:

“What shall we do?”

John answers concretely:

• honesty
• justice

St Gregory the Great writes:

“Repentance proves itself through changed conduct.”
(Homilies)

“Is he the Christ?” (3:15)

(On the Gospel of Luke)

Water baptism prepares; Christ baptises with Spirit and fire.

Typology

Purification anticipates transformation.

Judgment and renewal arrive together.

7. John’s Imprisonment: Truth and Consequence

Herod silences John.

St Augustine writes:

“Truth provokes resistance from threatened power.”

8. The Baptism of Jesus: Identity Revealed

“When Jesus also had been baptised…” (3:21)

He joins repentant humanity — not from need, but solidarity.
