Could you cite me canon law or something from the Bible or Tradition that tells you that?
SSPX is the living memory of the old Faith, pure and simple. It is exactly what the Church had always been, no more and no less.
I beg to disagree with you, from the histories I've read there have always been heresies and disagreement in the Church and the Holy Spirit has never failed it yet.
If it ever died, the old Church would have to be reconstructed out of books, rather than out of the living actions of living men.
How can it die unless it isn't the True Church to begin with?
I believe its destiny is to preserve the Catholic Church for saner times when future generations will understand better what went wrong and how to get back on track.
You believe.... And you will save the day right? Where is God's will in this? Where is His power that He can't save the Body of Christ from within? Have you given up on the Power of God?
What if Peter and Paul had thought that way? Even in Apostolic times there were disagreements in the Church and the Holy Spirit was allowed to triumph over egos and human selfishness. I lay my hope in God's hands and I believe He will solve the problems of this day. He, alone, can make it right.
