The Catechism in Questions & Answers

30. Are there biblical creeds?

Yes, even the Old Testament contains texts that bring common convictions of faith to expression. In one such creed it says: “Hear, O Israel: The Lord our God, the Lord is one!” (Deuteronomy 6: 4).
This profession, entitled “Hear, O Israel”, was one that the Israelites expressed together. Thereby they attested their belief in the one God in a time when the nations around them venerated many different gods.
The New Testament contains texts which employ specific formulations expressing that God grants salvation in Jesus Christ.
Examples of such New Testament creeds are:

  • “Jesus is the Lord!” (Romans 10: 9);
  • “Maranatha” (1 Corinthians 16: 22) = “O Lord, come”
  • “The Lord is risen indeed” (Luke 24: 34)

“[...] if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.”
Romans 10: 9-10
