Direct Answer
The transcript suggests that faithfulness is not merely preserving earlier practice, but recognizing and submitting to what God has actually commanded. In the case of the Judaizers, their error was not novelty but refusing a God-instituted change regarding Gentiles and the Law.
Support from Transcript
- Bercot says, "The problem with the Judaizers was not that they had changed the gospel, but that God had changed the gospel." - He clarifies that this was a change "from man's perspective," while "God's eternal purpose, of course, has never changed." - The earlier practice was real: "When the church was initially founded, persons had to become Jews and live by the law in order to become Christians." - The change was divinely initiated: "He broke down the wall of separation between the Jews and the Gentiles." - It required revelation: "It took a miraculous vision and a direct voice from the Holy Spirit" in Acts 10. - The Judaizers "clung to the original gospel and refused to accept God's modifications to it."

The transcript does not give a general method for discerning later changes, but it does warn that tradition can become resistance when God Himself has clearly acted.
