ISB ~ Romans 2 v6

according to his works:Paul looks ahead to the Last Day, when the life of every person is unrolled before God, and every thought (1 Cor 4:5), word (Mt 12:36), and deed (2 Cor 5:10) is weighed in the balance of divine justice. That God will determine his verdict on the basis of human works is a teaching that originates in the OT (Ps 62:12; Prov 24:12). It was later confirmed by Jesus (Mt 16:27) and reiterated by the apostles (2 Cor 5:10; 1 Pet 1:17). Paul is here stressing that Jews and Gentiles will be held to the same standard of judgment (CCC 682).
