We also can not presume salvation where the Church does not teach that it is present.
I agree.
It is also true, we can and should presume salvation where the Church teaches it.
THE TEACHINGS OF THE CATHOLIC CHURCH
CATHOLIC ENCYCLOPEDIA Divine Providence
explains the ultimate perfection, to which God has destined the human race.
.
This, the beneficent purpose of an all-seeing Providence, is
wholly gratuitous, entirely unmerited (Romans 3:24; 9:11-2).
.
It extends to
all men (Romans 2:10; 1 Timothy 2:4),
even to the reprobate Jews (Romans 11:26 sq.); and by it all God’s dealings with man are regulated (Ephesians 1:11).
.
It extends to every individual, adapting itself to the
needs of each (St. John Chrysostom, Hom. xxviii in Matt, n. 3 in; P.G., LVII, 354).
.
All things are created and governed
with a view to man, to the
development of his life and his intelligence, and to the satisfaction of his needs (Aristides, i, v, vi, xv, xvi

.
.
His wisdom He so
orders all events within the universe that the end for which it was created may be
realized.
.
He directs all, even evil and sin itself, to
the final end for which the universe was created.
Evil, therefore, ministers to God’s design (St. Gregory the Great, op. cit., VI, xxxii in “P.L.”,

That end is that
all creatures should manifest the glory of God, and
in particular that man should glorify Him, recognizing in nature the work of His hand,
serving Him in obedience and love, and thereby attaining to the full development of his nature and to
eternal happiness in God.

303 The sacred books powerfully affirm
God’s absolute sovereignty over the course of events.
.
CCCS 1996-1998; Justification comes from grace (God’s free and undeserved help) and is given to us
to respond to his call.
This call to eternal life is supernatural, coming TOTALLY
from God’s decision and surpassing ALL power of human intellect and will.
.
There is a
supernatural intervention of God in the faculties of the soul, which
precedes the free act of the will, (De fide).
.
308 The truth that God is at work in
all the actions of his creatures is inseparable from faith in God the Creator.
God is the
first cause who operates in and through
secondary causes:
"For God is at work in you,
both to will and to work for his good pleasure."171
Far from diminishing the creature’s dignity, this truth
enhances it.
307 God thus enables men to be intelligent and free,
causes in order to complete the work of creation, to perfect its harmony for their own good and that of their neighbors.
Though often unconscious collaborators with God’s will, they
can also enter deliberately into the divine plan by their actions.

Aquinas said, "God changes the will
without forcing it . But he can
change the will from the fact that he himself operates in the will as he does in nature," De Veritatis 22:9. 31. ST I-II:112:3. 32. Gaudium et Spes 22; "being …
