When the phrases "word of God" or "word of the Lord" appear in Acts and the epistles, they almost always refer to oral preaching, not to Scripture. For example:
"When you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God" (1 Thess. 2:13).
If we compare this passage with another, written to the same church, Paul appears to regard oral teaching and the word of God as synonymous:
"Keep away from any brother who is living in idleness and not in accord with the tradition that you received from us" (2 Thess. 3:6).
a. The reference to "He shall be called a Nazarene" cannot be found in the Old Testament, yet it was "spoken by the prophets" (Matt. 2:23). Therefore, this prophecy, which is considered to be "God’s word," was passed down orally rather than through Scripture.
b. In Matthew 23:2–3, Jesus teaches that the scribes and Pharisees have a legitimate, binding authority based "on Moses’ seat," but this phrase or idea cannot be found anywhere in the Old Testament. It is found in the (originally oral) Mishnah, which teaches a sort of "teaching succession" from Moses on down.
c. In 1 Corinthians 10:4, Paul refers to a rock that "followed" the Jews through the Sinai wilderness. The Old Testament says nothing about such miraculous movement. But rabbinic tradition does.
d. "As Jannes and Jambres opposed Moses" (2 Tim. 3:8). These two men cannot be found in the related Old Testament passage (Ex. 7:8ff.) or anywhere else in the Old Testament.
In the Council of Jerusalem (Acts 15:6–30), we see Peter and James speaking with authority. This Council makes an authoritative pronouncement (citing the Holy Spirit) that was binding on all Christians:
"For it has seemed good to the Holy Spirit and to us to lay upon you no greater burden than these necessary things: that you abstain from what has been sacrificed to idols and from blood and from what is strangled and from unchastity" (Acts 15:28–29).
In the next chapter, we read that Paul, Timothy, and Silas were traveling around "through the cities," and Scripture says that "they delivered to them for observance the decisions which had been reached by the apostles and elders who were at Jerusalem" (Acts 16:4).
