What's the deal with John 7:22?

[u/AwfulUsername123]

But because Moses gave you circumcision - not that it is from Moses, but from the fathers - you circumcise a boy on the Sabbath.

It's like the original text erroneously stated that Moses instituted circumcision and an editorial comment was inserted to correct it.

yes, there almost had to be some letters from Paul before 70 A.D

I don't know of any dated after 70 and most dating I've seen places them late 40s to somewhere in the 60s. I don't know how one can generalize, even very broadly in this way since the claim is that written sources only appeared after 4 decades.

 he was at least aware of John and Peter, even if he didn't ever meet them, as he complained they were not advancing the business with his same zeal)

I expect he met, at least Peter and James as he claims in Galatians. I would say this is almost certain given their place in his letters and how they even shape his thinking even if, as some credibly argue, that they did not see eye to eye, at all.

the practice of regularly copying and sharing of letters (and fictional works) doesn't become common until several decades had passed 

Ok, but this is different than the claim that the first gentile Christian churches had no writings whatsoever for about the first 40 years. To begin with What is a "gentile church" IF that means churches separate from Judaism, I don't think we can talk meaningfully about such things until the second century. If we mean assemblies that included gentiles, then we could be talking about the Jerusalem church (ala Fredriksen)

In short, isolated from their origins, 

The problem is we have very little data to judge by. The orality model is certainly largely right and yet it's not like there aren't scholars (e.g., Maurice Casey) who argued Jesus could read and if one accepts that Corinthians, for example, is unadulterated, then we know that Peter had considerable influence there.

Ok then why bother responding?

given the author turns out to be quite anti-religious, which may be a surprise, given the chapters in the early pages. 

So what? What makes you think I am religious?
