Opening - διανοίγων dianoigōn. See Luke 24:32. The word means to explain or to unfold. It is usually applied to what is shut, as the eye, etc. Then it means to explain what is concealed or obscure. It means here that he explained the Scriptures in their true sense.

And alleging - παρατιθέμενος paratithemenos. Laying down the proposition; that is, maintaining that it must be so.

That Christ must needs have suffered - That there was a fitness and necessity in his dying, as Jesus of Nazareth had done. The sense of this will be better seen by retaining the word "Messiah." "That there was a fitness or necessity that the Messiah expected by the Jews, and predicted in their Scriptures, should suffer." This point the Jews were unwilling to admit; but it was essential to his argument in proving that Jesus was the Messiah to show that it was foretold that he should die for the sins of people. On the necessity of this, see the notes on Luke 24:26-27.

Have suffered - That he should die.

And that this Jesus - And that this Jesus of Nazareth, who has thus suffered and risen, whom, said he, I preach to you, is the Messiah.

The arguments by which Paul probably proved that Jesus was the Messiah were:

(1) That he corresponded with the prophecies respecting him in the following particulars:

(a) He was born at Bethlehem, Micah 5:2.

(b) He was of the tribe of Judah, Genesis 49:10.

(c) He was descended from Jesse, and of the royal line of David, Isaiah 11:1, Isaiah 11:10.

(d) He came at the time predicted, Daniel 9:24-27.

(e) His appearance, character, work, etc., corresponded with the predictions, Isaiah 53:1-12.

(2) his miracles proved that he was the Messiah, for he professed to be, and God would not work a miracle to confirm the claims of an impostor.

(3) for the same reason, his resurrection from the dead proved that he was the Messiah.

Opening and alleging - Παρατιθεμνος, Proving by citations. His method seems to have been this:

1st. He collected the scriptures that spoke of the Messiah.

2d. He applied these to Jesus Christ, showing that in him all these scriptures were fulfilled, and that he was the Savior of whom they were in expectation. He showed also that the Christ, or Messiah, must needs suffer - that this was predicted, and was an essential mark of the true Messiah. By proving this point, he corrected their false notion of a triumphant Messiah, and thus removed the scandal of the cross.

Opening,.... That is, the Scriptures of the Old Testament, explaining and expounding them, giving the true sense of them; so this word is frequently used in Jewish writings (e), as that such a Rabbi "opened", such a Scripture:

and alleging, that Christ must needs have suffered, and risen again from the dead; he set this matter in a clear light, and made it plain and manifest, from the writings of the Old Testament, that there was a necessity of the Messiah's suffering and rising from the dead; or otherwise these Scriptures would not have been fulfilled, which have said that so it must be; for these things were not only necessary on account of God's decrees, and the covenant transactions the Son of God entered into, and on the account of the salvation of his people; but because of the types, promises, and prophecies of the Old Testament: the Scriptures which the apostle opened and set before them, and reasoned upon, showing the necessity of these things, very likely were such as these, Genesis 3:15 Isaiah 53:1 with many others:

and that this Jesus whom I preach unto you is Christ; he showed that all the things which were spoken of Christ, or the Messiah, in those Scriptures, were fulfilled in Jesus of Nazareth, who was the subject matter, the sum and substance of his ministry; and therefore he must be the Messiah, and the only Saviour and Redeemer of lost sinners.

(e) Zohar passim.

Opening and alleging

The latter word is rather propounding, or setting forth (παρατιθέμενος). See on set before, Luke 9:16; and commit, 1 Peter 4:19. Bengel remarks, "Two steps, as if one, having broken the rind, were to disclose and exhibit the kernel."

{2} Opening and alleging, that Christ must needs have suffered, and risen again from the dead; and that this Jesus, whom I preach unto you, is Christ.

(2) Christ is therefore the mediator, because he was crucified and rose again: and he is certainly not to be rejected because the cross is shameful.

whom...: or, whom, said he, I preach

Margin Christ

The Christ, i.e. that, according to the Scriptures, the Messiah must die and rise again. That Jesus was the Messiah was the second part of his argument.

3. Opening and alleging that Christ must needs have suffered, &c.-His preaching, it seems, was chiefly expository, and designed to establish from the Old Testament Scriptures (1) that the predicted Messiah was to be a suffering and dying, and therefore a rising, Messiah; (2) that this Messiah was none other than Jesus of Nazareth.

17:1-9 The drift and scope of Paul's preaching and arguing, was to prove that Jesus is the Christ. He must needs suffer for us, because he could not otherwise purchase our redemption for us; and he must needs have risen again, because he could not otherwise apply the redemption to us. We are to preach concerning Jesus that he is Christ; therefore we may hope to be saved by him, and are bound to be ruled by him. The unbelieving Jews were angry, because the apostles preached to the Gentiles, that they might be saved. How strange it is, that men should grudge others the privileges they will not themselves accept! Neither rulers nor people need be troubled at the increase of real Christians, even though turbulent spirits should make religion the pretext for evil designs. Of such let us beware, from such let us withdraw, that we may show a desire to act aright in society, while we claim our right to worship God according to our consciences.
