what they had learned through the prompting of the Holy Spirit.
... in order to keep the gospel forever whole and alive ...
the apostles left bishops as their successors,
their own teaching role to them.
This sacred tradition, therefore, and
sacred Scripture of both the Old and New Testament
are like a mirror in which the pilgrim Church on earth looks
at God ...
... the apostolic preaching,
which is expressed in a special way in the inspired books,
was to be preserved by a continuous succession
of preachers until the end of time.
