Did Paul know much of Jesus’s biography?

Paul’s letters report and allude to much known Jesus biography

See this page to explore the evidence, e.g.:

…examples abound where he does this

This is relevant because:
A) Knowing these bits of Jesus’s biography (geneology, status, sayings/teachings, ethical conduct, miracles, crucifixion details etc.) just is what it means for Paul to know Jesus biography generally.
B) Each known detail implies Paul has source(s) of knowledge on Jesus biography (and so likely knows more than he reports.)

Paul aimed to know Jesus biography

See this page to explore three evidences:

Examples abound of Jesus-bio that Paul wanted to know.
Paul visited Jerusalem/Peter in order to know it, and that took some amount of dedication.
Paul had clear reasons to want to know Jesus-bio, suggesting that he would go.

Paul's aiming to know Jesus-biography shows that Paul did know Jesus biography because witness-based Jesus biography was pervasive, especially for Paul; it was hard to avoid and easy to acquire.¹

We know Jesus biography was pervasive for Paul for three reasons:
• In general witness-based Jesus-biography was pervasive. • Paul was well-connected to the Jerusalem chuch (e.g. often there visiting ministry partners [like Peter, like James, etc.] and vice versa).
• Barnabas was as a leading Jerusalem church member, and Paul and Barnabas were ministry partners (e.g. they co-pastored a church for over a year).

Paul got tons of Jesus biography from the Jerusalem church

Rather than getting it primarily from other sources, the evidence we have suggests that Paul was overloaded with information on the historical Jesus that he received specifically from the apostolic/Jerusalem church (e.g. from the apostle Peter himself).

See this page to explie these three evidences:

Examples abound of info-bits we can tell Paul got from Jerusalem.
Paul's teachings matched the Jerusalem churches , and this is unlikely to be a coincidence.
Paul aimed to know Jesus biography and the Jerusalem church was the natural place to go (since he saw them as the experts).

If Paul got lots of Jesus-biography from the Jerusalem church, it would count as evidence for Paul's knowling lots of Jesus biography because the Jerusalem church was quite knowledgeable. It is where the apostles and primary witnesses resided.
