People really like to ignore the point that Paul was making in Romans 10:5-8 and its relevance to the surrounding verses because that context is contrary to how they want to interpret the surrounding verses, so correctly understanding Romans 10:9-10 in the context in which it was written is not contrary to the primary doctrine of Christianity, just contrary to your misunderstanding of those verses.As soon as you inserted the conditional statement, "though I think that Romans 10:5-8 referring to Deuteronomy 30:11-16 as the word of faith".
Then you are in conflict with the primary doctrine of Christianity.
All of the ways that God is referred to in the Bible describe aspects of His character, so calling on the name of Lord is recognizing who He is and is identifying with His character, which is also the way of salvation. The way to know God is by acting in accordance with His character, which is eternal life (John 17:3), which is also the way that God saves us from sin, which is acting in a way that is contrary to His character.Romans 10:13 for “Everyone who calls on the name of the Lord will be saved".
Romans 10:13 is connected with Romans 10:5-12, which references Deuteronomy 30:11-20 as the word of faith that we proclaim in regard to saying that God's law is not too difficult for us to obey, that obedience to it brings life, and a blessing, in regard to what we are agreeing to obey by confessing that Jesus is Lord, and in regard to the way to believe that God raised him from the dead (Titus 2:14). God's law is also His instructions for how to act in accordance with His character, which is why the Bible frequently uses the same terms to describe the character of God as it does to describe the character of God's law, such as with it being holy, righteous, and good (Romans 7:12), or with justice, mercy, and faithfulness being weightier matters of the law (Matthew 23:23). Romans 10:13 is also connected with Romans 10:14-16, which speaks against those who do not obey the Gospel. In Matthew 4:15-23, Jesus began his ministry with the Gospel message to repent for the Kingdom of God, which was a light to the Gentiles, and God's law was how his audience knew what sin is, so repenting from our disobedience to it is the way to obey the Gospel. In regard to calling on the name of the Lord, Jesus also asked why people called him Lord, but do not do what he said (Luke 6:46).
Paul îs the one who chose to make the point that he made in Romans 10:5-8 in the place that he made it, so if Paul hadn't made that point where he did someone else had made that point in a different book, then you might have room to accuse me of welding that together, but as it stands your problem is with what Paul wrote, not with me.What you have done is weld the reconciliation of mankind to God through Jesus Christ. With your own legal obedience to the law, thereby generating an alternate gospel. The key word in your interpretation is "though", hence you add, "though I think that Romans 10:5-referring to Deuteronomy 30:11-16 as the word of faith".
This is not my position. It is not the case that we need to add our obedience to God's law as if what Jesus accomplished were not enough. Jesus is the embodiment of God's word expressed by setting a perfect example of how to walk in obedience to it for us to follow, so us embodying God's word through following his example is not adding something of our own to who Jesus is. It is contradictory to think that we should rely on God's word made flesh for salvation, but not obediently rely on God's word for salvation.Jesus + obedience to the law = salvation, is a blatant heresy.
What you fail to understand is that the reconciliation that Jesus performed in His own blood. Was a permanent and eternal redemptive act, performed by Jesus alone, a divine reconciliation for humanity. Nothing added, as there is nothing we can do to initiate our own salvation.
Our salvation from sin would be incomplete if we were only saved from the penalty of our sin while we continued to live in sin, so there must also be an aspect of our salvation that we are experiencing in the present by Jesus leading us to obey God's law. In Titus 2:11-13, our salvation is described as being trained by grace to do what is godly, righteous, and good, and to renounce doing what is ungodly, so it is not the case that we are required to have first done those works in order to become saved as the result, and it is not the case that we are rehired to do those works as the result of having first been saved, but rather God graciously teaching us how to experience doing those works is itself the content of His gift of saving us from not having that experience.
"if you confess with your mouth Jesus as Lord,
It is contradictory to confess that Jesus is Lord while not obediently submitting to him as Lord by being a doer of God's law.
and believe in your heart that God raised Him from the dead
Even the demons believe that God raised Jesus from the dead as a historical fact, so that doesn't do anyone any good without understanding what Jesus accomplished through the cross and what that means for how we should live our lives by becoming zealous for doing good works in obedience to God's law.
you will be saved
It is contradictory to be saved from not being a doer of God's law while not being a doer of God's law.
Things that involve our own effort do not involve relying on anyone else, so it is contradictory to think that relying on God's instructions involves relying on our own effort. If God's law were His instructions for how to gain our own righteousness, and God does not want us to do that, then it would follow that God therefore does not want to be obeyed, which is absurd, therefore it is not God's instructions for how to gain our own righteousness, but for how to testify about His righteousness. Likewise, the purpose of doing good works in obedience to God's law is not to establish our own goodness, but to testify about God's goodness, which is why our good works in obedience to Him give glory to Him (Matthew 5:16). Thinking that God's law is about gaining our own righteousness has always been a fundamental misunderstanding of the goal of why we should obey it (Romans 9:30-10:4).The death and resurrection of Jesus stands on it's own with no qualification.
The law involves your effort at your own reconciliation, your own attempt at gaining righteousness.
You can join a hundred other heretical organizations that add something to Christ's reconciliation.
Jesus + my obedience = salvation.
