When either

the Roman Pontiff, or

the body of bishops together with him

defines a judgment

they pronounce it in accord with Revelation itself ...

Under the guiding light of the Holy Spirit,

Revelation

is thus religiously preserved and

faithfully expounded in the Church.

The Roman Pontiff and

the bishops,

strive painstakingly and by appropriate means

to inquire properly into that Revelation and

to give apt expression to its contents.

... they

do not allow that there could be any new public revelation

pertaining to the divine deposit of truth.
