But the word that they heard did not profit them,
for they were not united in faith with those who listened ...
Therefore, let us strive to enter into that rest,
so that no one may fall after the same example of disobedience.
"We guard with care the faith that we have received from the Church, for without ceasing, under the action of God's Spirit, this deposit of great price, as if in an excellent vessel, is constantly being renewed and causes the very vessel that contains it to be renewed."
-- CCC 175
