2-6. At what age did Jesus start his public ministry?

According to The Urantia Book (the 5th Epochal Revelation), Jesus began his public ministry shortly after his baptism by John the Baptist, when he was almost thirty-one and one-half years old.

This is explicitly stated in Paper 136: Baptism and the Forty Days, section 136:2.8:

"(Jesus was almost thirty-one and one-half years old when he was baptized. While Luke says that Jesus was baptized in the fifteenth year of the reign of Tiberius Caesar, which would be A.D. 29 since Augustus died in A.D. 14, it should be recalled that Tiberius was coemperor with Augustus for two and one-half years before the death of Augustus, having had coins struck in his honor in October, A.D. 11. The fifteenth year of his actual rule was, therefore, this very year of A.D. 26, that of Jesus’ baptism. And this was also the year that Pontius Pilate began his rule as governor of Judea.)"

Key context from the revelation:

• Jesus' baptism marked the decisive moment when he heard the Father's call to "be about his Father’s business," confirming his full readiness after completing his human experience (Paper 136:2.6–2.7).
• This event launched his public work: "JESUS began his public work at the height of the popular interest in John's preaching..." (Paper 136:0.1).
• Prior to this, he lived a normal human life—supporting his family, traveling extensively for personal experiences and preparation (detailed in Papers 129–135), and engaging in what the text calls a "personal ministry" (e.g., private teaching and interactions during his late 20s), but not the open, widespread public ministry of teaching, healing, and proclaiming the kingdom.
• His public ministry proper began in A.D. 26–27 (after the 40-day seclusion following baptism), with initial activities in Perea/Judea (taking over aspects of John's work quietly), then moving northward (Paper 141: Beginning the Public Work, starting January 19, A.D. 27).

This differs slightly from the biblical Luke 3:23 ("Jesus... was about thirty years of age" at the start of his ministry), as The Urantia Book provides a more precise chronology, adjusting for historical details on Tiberius' reign to align the baptism with A.D. 26, making Jesus nearly 31½ (born August 21, 7 B.C.).The book emphasizes that Jesus delayed public ministry until he had fully mastered human experience "as sojourners in the flesh" (Paper 129:4.8, noting completion by the end of his 29th year) and received the divine summons at baptism—ensuring his revelation of the Father was perfected through genuine mortal living.
