2 Does not this whole psalm seem to you to be written of yourself? Certainly you are hale and strong; and like a new apostle of Antichrist, when you are found out in one city, you pass to another. You are in no need of money, no crushing blow strikes you down, neither are you plagued as other men who are not like you mere brute beasts. Therefore you are lifted up into pride, and lust covers you as a garment. Out of your fat and bloated carcass you breathe out words fraught with death.
You never consider that you must some day die, nor feel the slightest repentance when you have satisfied your lust. You have more than heart can wish; and, not to be alone in your wrongdoing, you invent scandals concerning those who are God's servants. Though you know it not, it is against the most High that you are speaking iniquity and against the heavens that you are setting your mouth. It is no wonder that God's servants small and great are blasphemed by you, when your fathers did not scruple to call even the master of the house Beelzebub.
“The disciple is not above his master nor the servant above his lord.” If they did this with the green tree, what will you do with me, the dry? Much in the same way also the offended believers in the book of Malachi gave expression to feelings like yours; for they said, “It is vain to serve God: and what profit is it that we have kept his ordinance, and that we have walked mournfully before the Lord of Hosts? And now we call the proud happy; yea, they that work wickedness are set up; yea, they that tempt God are even delivered.”
Yet the Lord afterwards threatens them with a day of judgment; and announcing beforehand the distinction that shall then be made between the righteous and the unrighteous, speaks to them thus: “Return ye, and discern between the righteous and the wicked, between him that serves God and him that serves him not.”
