The Commentary on the Epistles of Peter and Jude is, in the variety of its themes, the clearness of its exposition, the stinging force of its rebukes, the simplicity and directness of its language, it is scarcely surpassed by any of Luther's other writings. On the great subject of justification by faith alone, he is here, as in his Commentary on the Epistle to the Galatians, full and emphatic. The relation of faith to works is clearly and carefully defined, while the subjects presented in the text afford full opportunity for discussing the great questions that concern the relative duties of civil and social life. The volume thus becomes at once a manual of doctrine and of duty. On the foundation of faith is reared the superstructure of a Christian life. Luther is seen to have fully apprehended the force of all the objections that could be urged against his teachings, and with convincing ability he vindicates them from every charge. Throughout the volume we have ever before us the earnest, devout spirit of the Reformer, for the most part unfolding in the simplest manner the great doctrines of the Gospel, but occasionally indulging in volcanic outbursts of indignation against the hierarchical corruptions of his day, and pouring out upon them the lava-tides of withering rebuke.
