Lots of food for thought in this video, it makes me think of many questions, which I will list at a later time.
The whole video is worth watching to the end, because whenever you think Fr MacGillivray is done he suddenly starts quoting more sources. I found it easy enough to understand at a full 2x speed (only 1 hr long).
What questions were not asked? What more should be said? Lets tie up any loose ends. It seems to me that, though the video may start off a bit weak as far as convincing a sede not to be sede, by the end it seems to be the safest conclusion not to be a sedevacantist.
