From Fr. John Zuhlsdorf
Christ, God, gave us the Catholic Church. It is the Church He founded. He gave us the sacraments as the ordinary means of salvation. He gave His own authority to the Church to teach about faith and morals. He gave us a visible point of reference for unity and security of knowledge for our membership in His Church: Peter and his successors and the apostles and their successors with Peter.
Knowingly reject the Church – and Peter – and the Church’s teaching and her discipline of Christ’s sacraments, and you place yourself on a path that might just land you in hell for eternity.
Catholics who dissent are in peril. If we in the Ordinariate stand firm, obedient, and faithful to the Magisterium; we have our traditional Mass, our liturgies, and we have the Cathechism as ‘authoritative’ for our congregations; dissent at one’s own peril.
