Luke 3:12

What great virtue there was in the discourse of the Baptist is manifested by this, that the Publicans, nay even the soldiers, he compelled to seek counsel of him concerning their salvation, as it follows, But the publicans came.

Then publicans also came to be baptized and said to him: Master, what shall we do? And he said to them: Do nothing more than what is appointed to you. The great power that the word of the blessed Baptist had and how much it …

He persuades the tax collectors not to overcharge, that is, not to demand anything extra.

Secondly, to the publicans seeking instruction, he gives a lesson about keeping the laws, when it is added: And the publicans also came to him, to be baptized. "Publicans were those who collected public taxes, or who were contractors of the revenues of the treasury, …

Then came also publicans to be baptized,....

Then came also publicans - He next instructs the tax-gatherers in the proper discharge of their duty: though it was an office detested by the Jews at large, yet the Baptist does not condemn it. It is only the abuse of it that he speaks against. If taxes be necessary for the support of a state, there must be collectors of them; and the collector, if he properly discharge his duty, is not only a useful, but also a respectable officer.

We have, in these verses, a specimen of John the Baptist's ministry. It is a portion of Scripture which should always be especially interesting to a Christian mind. The immense effect which John produced on the Jews, however temporary — is evident, from many expressions in the Gospels. The remarkable testimony which our Lord bore to John, as "a prophet greater than any born of woman," is well-known to all Bible readers. WHAT THEN WAS THE CHARACTER OF JOHN'S MINISTRY? This is the question to which the chapter before us supplies a practical answer.

The remarkable testimony which our Lord bore to John, as "a prophet greater than any born of woman," is well-known to all Bible readers. WHAT THEN WAS THE CHARACTER OF JOHN'S MINISTRY? This is the question to which the chapter before us supplies a practical answer. We should first mark — the holy boldness with which John addresses the multitudes who came to his baptism. He speaks to them as a "brood of vipers!" He saw the rottenness and hypocrisy of the profession which the crowd around him were making, and uses language descriptive of their case. His head was not turned by popularity. He did not care who was offended by his words. The spiritual disease of those before him was desperate, and of long standing — and he knew that desperate diseases need strong remedies! Well would it be for the Church of Christ, if it possessed more plain speaking ministers in our days — like John the Baptist. A morbid dislike to strong language; an excessive fear of giving offence; a constant flinching from directness and plain speaking — are, unhappily, too much the characteristics of the modern Christian pulpit. Uncharitable language is no doubt always to be deprecated. But there is no charity . . . in flattering unconverted people, in abstaining from any mention of their vices, or in applying smooth names to damnable sins! There are two texts which are too much forgotten by Christian preachers. In one it is written, "Woe unto you when all men shall speak well of you." Luke 6:26. In the other it is written, "Am I now trying to win the approval of men — or of God?

The publicans - See the notes at Mat 5:47. There is reason to think that the “publicans” or “tax-gatherers” were especially oppressive and hard in their dealings with the people; and that, as they had every opportunity of exacting more than they ought, so they often did it, and thus enriched themselves. The evidence of repentance in them would be to break off their sins in this respect, and to deal justly.
