2:5 What is the "Day of Wrath" Paul refers to here?
The day of wrath Paul refers to here is the final judgement - the Great White Throne Judgement, which will take place after the thousand years reign of Christ. Scripture calls it the second death (CP Rev 20:6, 12-15).
After describing the sinfulness of ungodly pagans in Ro 1:18-32, Paul turns his attention in Ro 2 to those who censoriously criticize and judge others for sinning.
Primarily he is addressing the Jews, but secondarily he is addressing everyone who judges others while at the same time they are themselves in sin. In condemning others they condemn themselves and store up God's wrath against them in the Day of Judgement (CP V1-4 with 16-29).
