As I say, it is hard now to retrace every step of that path but I want to give a structure to the considerations that follow, so I will organise them very much in the order which they occurred to me. My initial considerations concerned the episcopal consecrations of 1988 and so were connected to canonical issues. The second body of considerations concerned theological points of controversy, and were connected to the Church’s teachings and to Vatican II. My final considerations concerned the liturgy, and were thus connected to the Church’s worship. What horrified many of my friends and family at the time was not merely my separating from the SSPX, but my questioning the SSPX theses almost right across the board. What they did not understand was my realisation that, in each of these three areas – canonical, theological, liturgical - the SSPX had, albeit very worthily and with serious reasons, made the same false step. That at least is my opinion. I hope to make their false step clearer in due course.
