St. Paul simply is not talking of the good works that we know are fundamental for our salvation.

Other than the good work of believing in Jesus of Nazareth as Lord of all His Creation, born human of a virgin and also Son of the living God the Father, being soon baptised in the Name of the Father, the Son, and HOLY SPIRIT...

Other than this good work, what good works does the RCC teach are ALSO required for eternal salvation...?

And, BTW...

...Paul rarely said ANYTHING just simply.

Matthew 25:31-46 enumerates many. Any work of love and self-denial is what makes the faith perfect (James 2:22)
