Let every believer carefully learn the Gospel. Let him continue in humble prayer. We are molested not by puny foes, but by mighty ones, foes who never grow tired of warring against us. These, our enemies, are many: Our own flesh, the world, the Law, sin, death, the wrath and judgment of God, and the devil himself.
The arguments which the false apostles advanced impress people to this day. "Who are you to dissent from the fathers and the entire Church, and to bring a contradictory doctrine? Are you wiser than so many holy men, wiser than the whole Church?" When Satan, abetted by our own reason, advances these arguments against us, we lose heart, unless we keep on saying to ourselves: "I don't care if Cyprian, Ambrose, Augustine, Peter, Paul, John, or an angel from heaven, teaches so and so. I know that I teach the truth of God in Christ Jesus."
When I first took over the defense of the Gospel, I remembered what Doctor Staupitz said to me. "I like it well," he said, "that the doctrine which you proclaim gives glory to God alone and none to man. For never can too much glory, goodness, and mercy be ascribed unto God." These words of the worthy Doctor comforted and confirmed me. The Gospel is true because it deprives men of all glory, wisdom, and righteousness and turns over all honor to the Creator alone. It is safer to attribute too much glory unto God than unto man.
You may argue that the Church and the fathers are holy. Yet the Church is compelled to pray: "Forgive us our trespasses," I am not to be believed, nor is the Church to be believed, or the fathers, or the apostles, or an angel from heaven, if they teach anything contrary to the Word of God. Let the Word of God abide forever.
Peter erred in life and in doctrine. Paul might have dismissed Peter's error as a matter of no consequence. But Paul saw that Peter's error would lead to the damage of the whole Church unless it were corrected.
Therefore he withstood Peter to his face. The Church, Peter, the apostles, angels from heaven, are not to be heard unless they teach the genuine Word of God.
This argument is not always to our advantage. People ask: "Whom then shall we believe?" Our opponents maintain that they teach the pure Word of God. We do not believe them. They in turn hate and persecute us for vile heretics. What can we do about it? With Paul we glory in the Gospel of Jesus Christ. What do we gain? We are told that our glorying is idle vanity and unadulterated blasphemy. The moment we abase ourselves and give in to the rage of our opponents, Papists and Anabaptists grow arrogant. The Anabaptists hatch out some new monstrosity. The Papists revive their old abominations. What to do? Let everybody become sure of his calling and doctrine, that he may boldly say with Paul: "But though we, or an angel from heaven, preach any other gospel unto you than ye have received, let him be accursed."
VERSES 13, 14. For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it: And profited in the Jews' religion above many my equals in mine own nation.
This passage does not contain doctrine. Paul adduces his own case for an example. "I have," he says, "at one time defended the traditions of the Pharisees more fiercely than any of your false apostles. Now, if the righteousness of the Law had been worth anything I would never have forsaken it. So carefully did I live up to the Law that I excelled many of my companions. So zealous was I in defense of the Law that I wasted the church of God."
VERSE 14. Being more exceedingly zealous of the traditions of my fathers.
Speaking now of the Mosaic Law, Paul declares that he was wrapped up in it. To the Philippians he wrote: "As touching the law, a Pharisee; concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless." He means to say, "I can compare myself with the best and holiest of all those who are of the circumcision. Let them show me if they can, a more earnest defender of the Mosaic Law than I was at one time. This fact, O Galatians, should have put you on your guard against these deceivers who make so much of the Law. If anybody ever had reason to glory in the righteousness of the Law, it was I."
I too may say that before I was enlightened by the Gospel, I was as zealous for the papistical laws and traditions of the fathers as ever a man was. I tried hard to live up to every law as best I could. I punished myself with fasting, watching, praying, and other exercises more than all those who today hate and persecute me. I was so much in earnest that I imposed upon my body more than it could stand. I honored the pope as a matter of conscience. Whatever I did, I did with a single heart to the glory of God.
But our opponents, well-fed idlers that they are, will not believe what I and many others have endured.
VERSES 15, 16, 17. But when it pleased God, who separated me from my mother's womb, and called me by his grace. To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
Here Paul relates that immediately upon being called by God to preach the Gospel to the Gentiles, he went into Arabia without consulting a single person. "When it had pleased God," he writes, "I did not deserve it. I had been an enemy of Christ. I had blasphemed His Gospel. I had shed innocent blood. In the midst of my frenzy I was called. Why? On account of my outrageous cruelty? Indeed not. My gracious God who shows mercy unto whom He will, pardoned all mine iniquities. He bestowed His grace upon me, and called me for an apostle."
We also have come to the knowledge of the truth by the same kindness of God. I crucified Christ daily in my cloistered life, and blasphemed God by my wrong faith. Outwardly I kept myself chaste, poor, and obedient. I was much given to fasting, watching, praying, saying of masses, and the like.
