What Scriptures did the early scattered believers preach before the New Testament was written?
According to Acts 11:19, the early scattered believers preached the Old Testament Word, since no New Testament had yet been written. The only Word of God they had was the Old Testament, and they proclaimed it as they traveled, in this context to none but Jews only.
Les explains that Acts 11:19 describes Jews who were scattered abroad by the persecution that arose about Stephen, the persecution just read about back in chapter 7 and headed up by Saul of Tarsus. They traveled as far as Phoenix and Cyprus and Antioch, preaching the Word. Les stresses that the only Word they had was the Old Testament, because there was no New Testament written yet. So they went everywhere preaching the Old Testament Word, and in this context, to none but Jews only. Les says this is the verse that opened his thinking to see that God had been dealing only with the Jew, with exceptions, from the Old Testament promises.
Now they which were scattered abroad upon the persecution that arose about Stephen travelled as far as Phenice, and Cyprus, and Antioch, preaching the word to none but unto the Jews only.
