Historically, RC's have always confounded, and confused, the
two biblical doctrines of justification and sanctification.
Astralis said, "By your description, Salvation is a process which begins when a person first becomes a Christian, which continues through the rest of his life, and which concludes on the Last Day.
This definition allows the faithful Christian to do justice to all of the Biblical data by saying, "I have been saved; I am being saved; and I will be saved." It embraces all three of the aspects of salvation which are present in the biblical literature - not just take bits and pieces to say once saved, you definitely will go to heaven."
The above quote is a description of sanctification , more or less .
In fact their confusion on this matter has been so great, that
Romish councils and popes have pronounced anathemas on all
of us who dare to believe in the Bible's doctrine of justification
by grace alone(if its added with 'works', it stops being grace)
through faith alone.
You may have noticed that the two RCs on this thread are continuously trying to mix 'good works' into the picture.
"So, you're saying, you're saved if you believe AND follow Him?"
Our Protestant forefathers won this battle long ago. They defined the biblical view of justification in the old Confession-
"Those whom God effectually calleth He also freely justifieth; not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous: not for any thing wrought in them, or done by them, but for Christ's sake alone: not by imputing faith itself, the act of believing, or any other evangelical obedience, to them as their righteousness; but by imputing the obedience and satisfaction of Christ unto them, they receiving and resting on Him and His righteousness by faith: which faith they have not of themselves; it is the gift of God.
Rom.8.30; 3.22,24,25,27,28; 4.5-7; Tit.3.5,7; 1 Cor.1.30,31;
Rom. 5.17-19; Acts 13.38,39; Eph.2.7,8;..."
Assurance is based upon Justification, but we often think of
our salvation as being grounded upon our sins, or obedience.
When we are aware that we have sinned, we may feel shaken in our assurance of grace and salvation. Even losing assurance for a time. The old Confession defined Assurance
this way-
"Although hypocrites, and other unregenerate men, may vainly deceive themselves with false hopes and carnal presumptions of being in the favour of God and estate(state)
of salvation; which hope of theirs shall perish; yet such as truly believe in the Lord Jesus, and love Him in sincerity, endeavouring to walk in all good conscience before Him, may in this life be certainly assured that they are in the state of grace, and may rejoice in the hope of the glory of God; which hope shall never make them ashamed.
Job 8.13,14; Deut.29.19; Jn.8.41; Mt.7.22,23; 1 Jn.2.3; 3.14,
18,19,21,24; 5.13; Rom.5.2,5..."
"This certainty is not a bare conjectual and probable persuasion, grounded upon a fallible hope; but an infallible assurance of faith, founded upon the divine truth of the promises of salvation, the inward evidence of those graces unto which these promises are made, the testimony of the Spirit of adoption witnessing with our spirits that we are the children of God: which Spirit is the earnest(down-payment)
of our inheritance, whereby we are sealed to the day of redemption.
Heb 6.11,17-19; 2 Pet.1. 4,5, 10,11;...2 Cor.1.12; Rom.8.15,16; Eph.1.13,14; 4.30; 2 Cor. 1.21,22"
