The Letter to the Romans has fascinated and perplexed readers ever since antiquity, when the Church Fathers commented extensively on it. St. Thomas's Commentary on Romans, the first in his series of majestic commentaries on Paul's letters, stands out among commentaries on Paul's letters, both ancient and modern, as uniquely ample and refined.

Expansive in its broad theological concerns, incisive in its attention to the nuances of Paul's elaborate and complex argument, the Commentary on Romans shows the Angelic Doctor to be a singularly perceptive and insightful reader of the Apostle to the Gentiles. Inheritor of the great centuries of Patristic exegesis, tranquilly free from assumptions of later doctrinal disputes, and bringing to bear a mind saturated with Scripture, St. Thomas was able to lecture on Romans with an accuracy and thoroughness of interpretation that has never been equalled.
