I found this interesting resource today (here is the .pdf version). It’s a comparison of the wording of the 1689 London Baptist Confession with the Westminster Confession of Faith. Here is a link to James Anderson’s website where this stuff is housed. Since I’m plugging his comparison chart, I wanted to give him proper recognition.
While I haven’t had the chance to read through the document and compare it at particular points, I’ve been looking for such a parallel table for a while now. If anyone knows of any historical-theological work that’s been done comparing the two confessions, I’d be grateful for some bibliography. Go ahead and leave them as comments.
