This whole thing of him moving over is fishy to me. I'm sorry, too many cohencidences.
Nope. You haven't been following Brother Nathanael. For the past 6 months or so, you could see him getting increasingly frustrated and angry with the Orthodox, and with each day that passed, you could see him getting more frustrated. At the peak of said frustration, I actually chimed in and asked him to consider Traditional Catholicism, after which he followed me and started gradually making more and more pro-SSPX comments.
