Luke dates a preacher by naming seven officials
The AD 27 attached to this entry comes out of a list, not a calendar. Luke places the beginning of John's prophetic activity in the fifteenth year of Tiberius and synchronizes it with Pontius Pilate, Herod Antipas, Philip, Lysanias, Annas and Caiaphas.
What Luke then describes is movement, not a single occasion: John travelled through the region around the Jordan proclaiming a baptism of repentance for the forgiveness of sins. Mark likewise places him in the wilderness, baptizing in the Jordan and announcing that a more powerful figure would follow him.
What he told people to actually do
Luke's John demands practical changes rather than sentiment. A person with two coats should share with someone who has none; food likewise.
To tax collectors he says to stop collecting more than what is prescribed. To soldiers he says to stop extorting money and making false accusations, and to be satisfied with their wages.
Josephus remembers the movement, not the year
Josephus independently describes John as a moral teacher who drew crowds and practiced baptism. That corroborates the existence of the public movement, but not Luke's chronology.
Contemporary literary, coin and inscriptional evidence supports counting Tiberius's reign from AD 14, which puts his fifteenth year mainly in AD 29. The AD 26–27 calculation depends on counting from Tiberius's earlier shared authority with Augustus, a practice for which the surveyed contemporary evidence provides no support.
Luke also never says how much time passed between John's first preaching and Jesus's baptism.

What the sources leave uncertain
- Luke supplies a regnal year, not a month or day, and the beginning of a preaching movement may not correspond to one recoverable date.
- Contemporary literary, coin, and inscriptional evidence supports counting Tiberius’s reign from AD 14; this places his fifteenth year mainly in AD 29, not AD 27.
- An AD 26–27 calculation depends on counting from Tiberius’s earlier shared authority with Augustus, a practice for which the surveyed contemporary evidence provides no support.
- Luke does not state how much time passed between John’s first preaching and Jesus’s baptism.
