So, let's grant that the apostles began preaching the resurrection of Jesus every bit as early as Acts 2 says they did. Now we've pushed the resurrection-creed back to 33. a.d., even further back than Habermas would dare date the 1st Corinthians 15:3-4 "creed".

Are you willing to discuss the possible NT sources behind such "creed"?

Barry, I've already discussed the sources behind such creeds. There's no reason to go back into this issue. I encourage you to listen to the podcast and to also reference other resources at https://bellatorchristi.com concerning the multiple eyewitness testimonies concerning the risen Jesus.
