The Charism of Infallibility: The Magisterium
Bishops, teaching in communion with the Roman Pontiff
are to be respected by all
as witnesses to divine and Catholic truth.
In matters of faith and morals,
the bishops speak in the name of Christ, and
the faithful are to accept their teaching and
adhere to it with a religious assent of souls.
