Leander E. Keck asserts that because Romans is part of the New Testament, we can compare it with the other letters ascribed to Paul, as well as with what Acts reports about his message and mission. But the first readers of Romans had only this letter; they could compare it only with what they may have heard about him. While this commentary does from time to time compare Romans with what Paul had said before, it concentrates on Romans itself; what Paul says in this text should not be conflated withnor inflated into--what he thought comprehensively, though it is essential to understand that as well.
