... the individual bishops do not enjoy the prerogative of infallibility,

they can ... proclaim Christ's doctrine of infallibility...

when they are dispersed around the world ...

maintaining the bond of unity

among themselves and

with Peter's successor,

while teaching authentically on a matter of

faith or

morals,

  This authority is even more clearly verified when,

Gathered together in an ecumenical council,

they are teachers and judges of

faith and

morals for the universal church.
