I’m not quite sure I agree with your definitions.
Following are the Catechism’s definitions:
- Grace: “The free and undeserved gift that God give us to respond to our vocation to become his adopted children.” It is more than just knowledge of sin.
- Justification: The gracious action of God which frees us from sin and communicates “the righteousness of God through faith in Jesus Christ” (Rom 3:22)
- Sanctifying Grace: As sanctifying grace, God shares his divine life and friendship with us in a habitual gift, a stable and supernatural disposition that enables the soul to live with God, to act by his love.
- Salvation: The forgiveness of sin and restoration of friendship with God, which can be done by God alone.
- Everlasting salvation: This must be your own term. Salvation is salvation. There will be no need for salvation in heaven. We are saved from our sins. Since sin cannot exist in heaven why would anyone in heaven need to be saved?
I was not actually attempting to define the terms though… I was just explaining the existence of salvation, and how it is acquired, in relationship to what I
do know. This was just a little summary that I made… There is much much more than this!
Anyways, it looks like there are two terms in particular that you disagree with…
GRACE:
Grace to me is a supernatural gift from God… Charism, miracles, tongues, etc. are all considered special graces.
CCC para 2004 states: "Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; he who teaches, in his teaching; he who exhorts, in his exhortation; he who contributes, in liberality; he who gives aid, with zeal; he who does acts of mercy, with cheerfulness.55 "
So apparently there are many many types of graces… I believe that it is acceptable to consider the
acknowledgement of sin and the
need for forgiveness as actual
graces… Isn’t it?
Everlasting Salvation:
OOps… You’re right, I meant “
Eternal Salvation”…

CCC para 847 States: “Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience - those too may achieve eternal salvation.”
I will admit I cannot find a real definition for this either…

But I have done the best I can to understand it… I have come up with the following:
agapebiblestudy.com/charts/the%204%20different%20aspects%20of%20salvation.htm
“Sanctification: “Being made holy. The first sanctification takes place at baptism, by which the love of God is infused by the Holy Spirit (Romans 5:5). Newly baptized persons are holy because the Holy Trinity begins to dwell in their souls and they are pleasing to God. The second sanctification is a lifelong process in which a person already in the state of grace grows in the possession of grace and in likeness to God by faithfully corresponding with divine inspirations.
The third sanctification takes place when a person enters heaven and becomes totally and irrevocably united with God in the beautific vision. (Etym. Latin sanctificare, ‘to make holy’.)” Catholic Dictionary p. 393; CCC # 703, 767, 819-827, 1540, 1989-99, 2001”
You say that: “sin cannot exist in heaven,” which is why there is no salvation inside heaven… As much as I agree with you on that, why then does the Church teach of a third sanctification, upon entering heaven?
If sanctification is one of the 4 parts of salvation, and sanctification is eternal, then consequently, wouldn’t we say that salvation is eternal? They go together… right?
