15. It is unnecessary here to reply to those wicked and illiterate dolts, the Papists and Anabaptist factions, who explain Paul's words, "my tribulations for you," and similar passages, as teaching that one Christian can by his sufferings merit or aid in the salvation of others. Paul does not say, "My tribulations for you are designed to secure for you forgiveness of sins and salvation." He clearly declares, as the Scriptures everywhere do, that only Christ's sufferings are thus effective and for all men. Paul's thought may well be expressed—and every minister may say the same—in these words: "My preaching and my suffering are for your sake." Just as a parent may say to a child, "I must do or endure this for you."
True, works wrought and sufferings endured for another's sake are productive of the good and comfort of that one or of many, but the worker or sufferer does not thereby merit, either for himself or another, God's grace and eternal life. No, these things demand the offices of a being of another order—Christ. He through his sufferings exterminates your sins, and through his death gives you life. Then again, Paul is addressing those already Christians and having forgiveness of sins and all the requirements of a Christian; yet he suffers for them; that is, for their good—that in proportion as his enemies seek to oppose the Gospel, its influence may be widened and the faith of his followers strengthened.
16. In the effort to comfort and strengthen the Ephesians, Paul yet further glorifies and extols his tribulations in the words "which are your glory." What unheardof talk is this? Is it not much rather, as reason dictates and as all the world affirms, a disgrace to his followers that he lies there in prison? What greater dishonor can Christians suffer than to have their ministers and pastors—their instructors and consolers—shamefully arrested? So it seems to the world, it is true; but I tell you, in God's sight and in reality, this trial is a great honor to you, one of which you may proudly boast. This very disgrace and provocation you may turn squarely to your good, saying: "From the very fact of our disgrace, I know the doctrine is true and divine. For it is the lot of the Word of God and of salutary doctrine, together with the supporters of the same, to be defamed and persecuted by the world and the devil." Such persecution is but glory and honor to Christians. Paul says in Romans 5, 3, "We rejoice in our tribulations." In other words, we regard them as glorious, beneficial, precious, blessed.
