The text of Galatians isn’t particularly interesting to textual critics as there are few meaningful issues with the text and nothing that serves as a “crux” that brings enjoyment in debating. However, this month over at Evangelical Textual Criticism there have been a few discussions:
Jan 12 HMWN in Gal 1.3: the problem of arguments from Pauline style
Jan 13 Resolving a mystery in NA26 & 27 at Gal 1.1
Jan 19 PERI/UPER in Gal 1.4
