The Thessalonians of Acts 17 did not reject the message of Christ because of sola scriptura. They rejected the message Paul brought them for the same reason the religious leaders of Israel rejected Jesus.
The Thessalonians rejected the gospel because they did not believe the words of Scripture. They did not deliberate for three weeks and decide that Paul’s words contradicted the Torah; they simply refused to believe, because the words of Scripture clashed with their tradition.
“Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom ye trust. For had ye believed Moses, ye would have believed me: for he wrote of me. But if ye believe not his writings, how shall ye believe my words?”—John 5:45–47
Psalm 119: 38
