These and similar things Peter calls "cunningly devised fables." They are exaggeratingly pretended to be the product of great wisdom and art, and are rendered sweet and palatable to reason. So has all idolatry, heresy, and false doctrine, from the beginning on, prevailed, being fashioned and most beautifully adorned by people learned and wise and held in the esteem of the world.
50. How admirable did the position of Arius and his adherents appear in comparison with the true faith concerning the divinity of Christ, when they declared that though Christ should be exalted above all angels and creatures, and that all honor, dominion and power in heaven and on earth belong to him, yea, that he is quite equal to God—all this, yet he is not "homo-ousios"; that is, he is not in one undivided, divine, eternal essence, which is of such unity that it could be imparted to no one else. It would be too much to say that a man is God, etc. With such pretense was a great multitude of Christians seduced. Even few bishops remained in the pure doctrine and faith. And afterward this poison prevailed among the wise people of Asia and Greece, until Mohammed, with his Saracens and Turks, had miserably corrupted the greatest part of the world.
51. Likewise the Pope has adorned and colored with a glorious form his abominations and idolatry, claiming for his order of service that it is a meritorious and beautiful thing. Again, he calls attention to the serviceableness of the beautiful, orderly government and power of the Church, with its well regulated gradations of office and position—bishops superior to the ordinary priests, and over the bishops Saint Peter's chair at Rome. In that chair is vested the authority for the convocation of general councils so often as these may be necessary. These councils are to judge and decide in all matters of faith, and their decisions everyone must follow and obey. Again, he boasts what great service and consolation to the whole world is the work of the priests in the mass, when they daily renew and offer to God the sacrifice made by Christ on the cross. This is the sweet wine in the "golden cup" of the scarlet harlot of Babylon, with which she has made drunken all kings and nations, Rev 17, 2-4.
52. Where the devil finds those who give ear to such fables, he takes them captive and so fills them with these falsehoods that they neither see nor hear anything else. They think their belief is the only one, and they will not suffer themselves to be instructed out of God's Word. And so, in their madness, without rightful intelligence of faith and all principles of pure doctrine, they continue in their darkened mind, with their fantastic, lying prattle, without repentance and amendment, having no grace to learn or do anything good. This is amply proved by the example of all seditious spirits.
53. Therefore, Peter admonishes us to be "sober and watchful," especially in spirit, and to guard ourselves against this sweet poison and these beautiful, adorned lies and fables of the devil. He teaches us how to equip and defend ourselves against his wicked devices.
IV. "Whom withstand stedfast in your faith."
54. The true defense and resistance, in which we are to be sober and watchful, is to be well grounded in God's Word and cling firmly thereto when the devil seeks, with his cunningly devised fables, born of human understanding and reason, to overthrow our faith. Reason is the devil's bride, and always vaunts itself wise and skilful in divine things, and thinks what it holds to be right and good must be accounted so before God. But faith holds to God's Word alone. It knows that before God, human wisdom, skill and power, and whatever gifts and virtues man may have, count for nothing. Only his grace and the forgiveness of sins in Christ has value. Therefore, faith can repel and defeat all these fine pretensions and cunning fables.
55. Worldly dominion and authority boasts before God in this fashion: My crown is a crown in God's sight, for my power and sovereignty have been given me by God. Therefore, whatever I say he must respect and regard as valid, and everyone must endorse my words and actions.
The wise philosopher or jurist would thus give expression to his boasts and pretensions: We are the learned, the wise rulers of the world, and have admirable laws and statutes. We have superior and beautiful doctrines concerning good works and virtues. Men must listen to us and allow our judgment to have precedence. He who can do, or does, such things as we have done is, in God's sight, superior to others.
