This looks like it will be an interesting video series. The following video is the first one, an introduction to the video series by Father Steven McDonald. It is going to be a series of short videos that talk about the Society, Archbishop Lefebvre, and the controversial issues that came out of the Second Vatican Council – Religious Liberty, Ecumenism, etc.
According to the introductory video, these will be released every two weeks. You can see the upcoming list of them HERE.
The SSPX has started a new YouTube channel for these, and probably more, videos as well. HERE.
