Hello eleos nice to see you
.
According to the scriptures we are only held accountable to God for what we know not what we do
not know *see Acts of the Apostles 17:30-31; James 4:17. That said the
context of Romans 2:14-16 is
Romans 2:11-14 [11], For there is no respect of persons with God (Jew or gentile is the subject matter). [12], For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law; [13], For not the hearers of the law are just before God, but the doers of the law shall be justified.
Paul's argument here is that whether Jew of Gentile all have broken God's law and this theme continues through to Romans 3:9-23 showing that all have sinned and fall short of the glory of God. The scriptures continue Romans 2 saying...
Romans 2:14-16 [14], For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law to themselves: [15], Which show the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another...
For me all these scriptures are saying is that even if we do not know or follow God's Word it is what we do from the heart that bears witness to our actions if they are acceptable with God or not acceptable with God. It is not saying that Gentiles do not sin as Paul shows through Romans 2 and Romans 3 that no one is righteous before God and that all have sinned and fall short of the glory of God (Romans 3:9-23) and because of this we need God's forgiveness *Romans 3:23.
When applying the term "
the scriptures are the only rule of faith" I am only meaning that faith comes by the Word of God and is where our faith comes from. Nothing more.
God bless.
