Rick Brannan of Ricoblog has finished his in-depth series on the Didache. It ended up running to 20+ parts. The main post has links to all posts. But all the posts can be brought up (in reverse chronological order) from this category link.
On Rick’s second blog, PastoralEpistles.com, he’s started a series that will work through possible quotations and allusions to the Pastoral Epistles found in the writings of the Apostolic Fathers. The intro post is up and will function as a table of contents as the study progresses.
