Ed,
So here’s a quick look at scripture in the first eight chapters of Romans. All of Romans is a Catholic book, consistent throughout and consistent with the apostolic faith for 2000 years. St Paul and St James both believe we are saved by grace, through faith, working in love and that faith without works is dead. A dead faith can not save. Faith is made complete by works. An incomplete faith can not save.
Chapter 1 - St Paul is writing to believers (your thesis is that believers should be saved correct?)
8 First, I thank my God through Jesus Christ for all of you, because your faith is proclaimed throughout the world.
Chapter 2 - But the Believers will be judged by their deeds … only those that do good will have eternal life. Not all believers.
5 But by your hard and impenitent heart you are storing up wrath for yourself on the day of wrath, when God’s righteous judgment will be revealed. 6 For he will repay according to each one’s deeds: 7 to those who by patiently doing good seek for glory and honor and immortality, he will give eternal life;
Chapter 5 - Justified by Faith (this is very Catholic but notice it does not say justified by faith alone)
1 Therefore, since we are justified by faith
Chapter 5 - We rejoice in the hope of our salvation. The key word is hope, not assurance.
2 through whom we have obtained access to this grace in which we stand; and we boast in our hope of sharing the glory of God
Chapter 6 - The Wages of Sin is Death (again St Paul is writing to believers; believers can lose their salvation)
23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
Chapter 8 - The Believers Can Die Living in Sin (believers can lose their salvation)
13 for if you live according to the flesh, you will die; but if by the Spirit you put to death the deeds of the body, you will live.
Chapter 8 - Again St Paul refers to the hope, not assurance of salvation. If St Paul believed in OSAS, than why would he only hope?
24 For in hope we were saved. Now hope that is seen is not hope. For who hopes for what is seen?
