First, Luther has nothing to do with this. I neither use his notes, commentaries, nor translation. If I use the Greek, I go to the Greek that preceded him. Therefore your red herring has nothing to do with this.
I was using Romans 5:1 for example:
Romans 5:1 δικαιωθεντες ουν
εκ πιστεως ειρηνην εχομεν προς τον θεον δια του κυριου ημων ιησου χριστου
--ek pistews. That is the phrase that means "by faith." One cannot add anything to that phrase. It means "by faith alone," not "by faith plus baptism" or any other "plus." There is no plus sign. It is by faith alone. Luther has nothing to do with anything.
I never consulted Augustine. But I hear TS use the phrase "cooperate in love" until I get sick of the phrase. Face it. The RCC is a religion based on works. If one does not "DO" they will not make it to heaven. They must "keep" the sacraments for example, "keep" going to mass; "keep" confessing their sins to the priest, "be" baptized; etc. All of those are "works," things a man does. It is a religion of works not grace. In these things they "cooperate" with God. In Biblical salvation God has done it all.
No. I am a non-Cal who believes in eternal security.
If it is not by faith alone it is not by faith at all. When it is not by faith alone, then it is by faith plus works. The Bible speaks against that:
Ephesians 2:8 For by grace are ye saved through faith; and that
not of yourselves:
it is the gift of God:
9 Not of works, lest any man should boast.
--Clearly salvation is not of works; it is not of anything that you can do; not of yourself.
But he doesn't. He believes his works are meritorious. The entire RCC system is a system of works. No works; no salvation.
One of the most important verses in the Bible is John 3:3, "you must be born again."
Verse 5 says: You must be born of water and of the Spirit.
The RCC wrongly interprets "water" to mean baptism, thus relegating the doctrine of regeneration to baptismal regeneration which the Bible does not teach. Baptism does not equal salvation. Water is not magic that can save your soul.
This demonstrates that they do not believe "salvation is all of God," but they must do their part. They must baptize. Christ's blood was not sufficient enough to cover all their sins, they must baptize to do what Christ was not able to complete on the cross. Baptism = new birth. That is in the Catechism. And that is blasphemy.
I am redeemed the day that I put my trust in Christ. All my sins: past, present and future were put under the blood on that day. During this life I go through a process of sanctification. When I reach heaven I will be glorified, but not until then. The Bible states that "we wait for the redemption of our bodies." It won't happen on this earth. That does not leave room for purgatory as some wish to think.
To be absent from this body is to be present with the Lord.
If I am saved, when I die I leave this sinful body behind and go straight to heaven. My sinful body stays here. To think that anything sinful is entering into heaven is nonsense. All those sins have been forgiven.
And that is what is important. That is why I am secure in Christ. That is why I have eternal salvation that I will never lose. Eternal means eternal; never can be lost. If it was lost it wouldn't be eternal and Christ would be a liar. Eternal cannot mean temporal.
Sin on this earth may cause a loss of fellowship, as disobedience of a child will cause a rift between father and son. But the father does not disown his son. Neither will the heavenly Father ever disown his children who have been born into his family.
Choosing between two things is not a work. I wish I could have a job that just required faith. Would you hire me and pay me for "faith"? Would you give me money to put my trust not just in God but in other things. Just to tell you that I trust this or that. Is that work? No.
Would you pay me because I receive your gifts?
Would you pay me because I earn the money, work for the money that you will give me at the end of the day for my labor? Hopefully. It is the law.
That is the difference that Paul explains in Romans 4:1-5.
