I give a ‘dittto’ to the Word on Fire blog you expressed above. Not to mention Jon’s site, “the Hump of the Camel”.
I’ve also on occasion enjoyed the very Catholic Ed Feser’s blog, even though I disagree with him on oodles of things. I’d hate to have to debate him. But the few of his blogs I’ve read have been occasions of education for me.
Though I’m not a regular frequenter, I really enjoyed “The O’Flynn” (TOF) in his “Great Ptolemaic Smackdown” which makes for an entertaining and informative, if somewhat caustic read. Just follow that series through all its parts to its conclusion (which you will because you won’t be able to stop reading it - and there are lots of pictures!), and you’ll be rewarded with a lot of great history and references.
