And one more thing while I think of it. Here's a truth you can stuff in your hash pipe and puff on until the cows come home: Roman's 3 is the universal, divinely inspired indictment against all mankind (unbelieving Jews and Gentiles).
Secondly, Paul didn't have include Ps 14:1 since it should be understood from everything the NT teaches that all unbelievers are atheists in the practical sense. How? Because all unbelievers live their every day lives as though there is no God. Practically speaking, all unbelievers are atheists because they don't believe in the one and only true God, consequently their sinful lifestyles reflect this reality. Therefore, Paul's universal indictment against all humanity is valid.
