John Calvin’s Commentaries On St. Paul’s Epistles To Timothy, Titus And Philemon [EPUB ebook] 

Calvin produced commentaries on most of the books of the Bible. His commentaries cover the larger part of the Old Testament, and all of the new excepting Second and Third John and the Apocalypse. His commentaries and lectures stand in the front rank of Biblical interpretation.
The foundation of every code of rules for guiding the ministers of Christ must be sought, not in the judgments of uninspired men, however able and judicious, but in the Holy Scriptures, and chiefly in the Epistles to Timothy and Titus, the accurate interpretation of which is therefore unspeakably valuable. CALVIN has examined them with his usual skill, and will be heard with profound attention. His candor appears to more than ordinary advantage. Never does he press the words of the Holy Spirit beyond what appears to him to be their natural meaning, or depart from the rigid discharge of his task as an expositor for the sake of giving undue prominence to his peculiar views. On this point it may be sufficient to refer to his remarks on the authority which some ministers of the gospel appear to have exercised over others, as a specimen of his unshaken determination to adhere to the sacred records, and of his utter indifference to any use that might be made of such statements by those whose views of church-government differed from his own. Nowhere is his sterling honesty more conspicuous.
