This is a talk given at The Roman Forum in 1988 by Michael Davies on why there is a traditionalist movement in the Church. In his singular style Davies gives a good overview of the concerns that prompted the formation the movement.
The audio/video was edited and made available by Vox Catholica, a traditionalist resource sympathetic to the SSPX. I am grateful for this resource, and I feel they have done an excellent job in presenting it. However, just so I am clear at this time, although I am somewhat sympathetic of the SSPX, I am not personally supportive of them, at least not at this time given their standing with the Church, but I find the lecture very much worth listening to. I also pray the SSPX would be fully reconciled with the Church, and eventually given their due as God sees fit.
