(3) Opening and alleging.--The latter word is used in the sense of bringing forward proofs, and the two words imply an argument from the prophecies of the Messiah, like in kind to that at the Pisidian Antioch. In the intervals between the Sabbaths, the Apostle worked, as usual, for his livelihood, probably, of course, as a tent-maker (2Thessalonians 3:8).

That Christ must needs have suffered.--Better, that the Christ, as pointing to the expected Messiah, the Anointed of the Lord, whom all Jews were expecting, but whom they were unwilling to recognise in the crucified Jesus. The argument was, therefore, to show that prophecy pointed to a suffering as well as a glorified Messiah, and that both conditions were fulfilled in Jesus.

Verse 3. - It behooved the Christ to suffer, and to rise for Christ must needs have suffered, and risen, A.V.; whom, said he for whom, A.V.; proclaim for preach. A.V.; the Christ for Christ, A.V. The line of reasoning adopted by St. Paul in his preaching to the Thessalonian Jews was the same as that of our Lord to the disciples and apostles on the day of his resurrection, as recorded in Luke 24:26, 27; 44-47, and that of St. Peter (Acts 2:22-36; Acts 3:18; Acts 4:11, etc.), and it is irresistible. The fulfillment of prophecies relating to the Messiah in the person of Jesus is like the fitting of a key to the intricate wards of the lock, which proves that it is the right key. The preacher of the gospel should carefully study and expound to the people the word of prophecy, and then show its counterpart in the sufferings and glory of Christ. This did St. Paul. Opening (διανοίγων); as our Lord had done (διήνοιγεν ἡμῖν τὰς γραφάς, Luke 24:32), the hidden meaning of the prophecies, and then alleging (παρατιθέμενος), setting before them the propositions which had thus been established. The process is described in Luke 24:27 as interpreting ("expounded," A.V.). In this verse the opening was showing from the prophets that the Messiah was to die and rise again; the alleging was that Jesus was that very Christ.

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.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.
