what does the bible say?
Jesus refers to Scripture as the written Word that originates from the mouth of God (Matthew 4:4). Jesus does not refer to oral tradition, but instead refers to the written Word numerous times (seven times in Matthew). Paul (2 Timothy 3:16) and Peter (2 Peter 1:21) refer to God and the Holy Spirit as the source for the written Word, not oral tradition.
Alternatively, form criticism aims to identify and analyze the literary forms, genres, and oral traditions behind the written text of Scripture. Scholars using this approach propose that biblical material—such as narratives, parables, poems, and laws–-took shape through repeated use in various worship or communal settings before being compiled into the documents we now recognize as the books of the Bible. This approach was popularized by German scholar Rudolf Bultmann, who used it to analyze presumed oral traditions behind the Gospels. However, form criticism is very limited in ability to produce trustworthy results, and the Bible shows that the words of the Bible come from God.
