What other thing saves (other than faith) in Romans 4:5-6, Titus 3:5, Ephesians 2:8-9, Romans 11:5-6?
Firstly you need to recognise that Paul is wring letters to people to address disputes and errors that have arisen. He is not writing a theological manual.
Secondly you need to take all relevant scriptures into account, not just cherry pick a few out of context.
Jesus said
"The one who believes and is baptized will be saved" (Mk 16;16). Do we ignore what Jesus said?
Peter just wrote:
"This prefigured baptism, which saves you now" (1Pet 3:20-21). Does that mean faith is not required?
Peter wrote "
And it shall be that whoever calls on the name of the Lord shall be saved" (Acts 2:21). Does that mean faith is not required?
Paul wrote:
For, “every one who calls upon the name of the Lord will be saved.” (Rom 10:13). Does that mean faith is not required?
Paul wrote:
"by grace you have been saved" (Eph 2:5). Does that mean faith is not required?
It seems to me that works are excluded from being conjoined with faith in what saves a man.
Again we need to look at the context.
Take Rom 4:5-4. Verse 4 says "
Now to one who works, his wages are not reckoned as a gift but as his due.". Paul is not referring works of any kind but a particular kind of work - one that
earns. If we are saved by a gift of God than it cannot be a work that earns what is due.
If we look at the previous chapter, Rom 3:28, Paul writes: "
For we hold that a man is justified by faith apart from works of law".
Works of the law refer to the Mosaic Law. If a man could keep those laws perfectly he would have earned salvation as a due.
Paul recognises two kinds of work -
works of the law and works that are
not works of the law. Works of love, for example, are not
works of the law. In Gal 5:6 Paul refers to "
faith working through love". It is works of love that James refers to in James 2, and when he writes "
You see that a man is justified by works and not by faith alone".
