810. 4.
The books of holy Scripture are entirely sufficient (John 20:30f.; 2 Tim.
3:16f.). Therefore another source of revelation is not necessary.
I distinguish the antecedent. The
book of Holy Scripture are entirely sufficient relatively and positively,
or in reference to the end intended in them, conceded; absolutely and
exclusively so that now another source of revelation is not to be admitted,
denied. I also distinguish the consequent: Another source of revelation
is not necessary absolutely and under every respect, denied; relatively or
in reference to the truths about which with the help of the Magisterium it is
sufficiently certain for us from Scripture, I subdistinguish; and still that
other source must be admitted as ordained by God, conceded; and that
other source must be rejected although it has been given to us by God
superabundantly, denied.
811. 5.
Holy Scripture contains the fullness of revelation (Gal. 1:8; Rev. 22:18).
Therefore Tradition by reason of
the fullness of Scripture does not surpass it.
I distinguish the antecedent.
Scripture in the cited texts bears witness that nothing human should be added
to the revelation given to us by the Apostles, and that it is not licit to
remove anything from it, conceded; Scripture in the cited texts says that
in itself all the per se revealed truths are contained, denied. (Joachim
Salaverri and Michaele Nicolau, Sacrae Theologiae Summa, 4 vols. [trans.
Kenneth Baker; Keep the Faith, Inc., 2015], 1B-309)
