Ah right. I missed the fact that you mentioned Feser. I examined the argument first, but shouldn't have bothered since you mentioned him. I've read his blog, and it's chock full of the bizarre reasoning such as above.

> <lots of words>

> A implies B without a single shred of justification

> <some more words>

> Therefore Jesus

I'd recommend not bothering with any of that. It's honestly not worth anybody's time except as a curio for how to dress up nonsense to look reasonable.
