Jer 7:11

“(Verse 11.) Has this house (or mine) become a den of thieves, as it is written (Vulg. Therefore), in which my name has been invoked in your eyes? I, I am: I have seen, says the Lord. I think this is taken from the Gospel: It is written: My Father's house shall be called a house of prayer: but you have made it a den of thieves (Matthew 21:13); or, as it is written in another Gospel, a house of trade (John 2:16). The Church of God turns into a den of thieves, when thefts, homicides, adulteries, sacrileges, perjuries, the invention of heresies, and all those crimes are committed within it: when the princes are inflamed with the torches of greed, and the once riches of kings possess a cheap or certainly not costly cloak. From this it follows: I, I am, I have seen, says the Lord. My eyes have seen what you think is hidden: the darkness of treasures does not escape my consciousness. He who was rich became poor for us, now he blushes at our wealth (I Cor. VIII), and says: Woe to you, the wealthy, who have your consolation (Luke VI).”

“"Has not this house, in which my name is invoked, been made a den of thieves before your eyes? I who am, I have seen it, says the Lord." I believe that it was from here that the Gospel took: "It is written, 'My father's house will be called a house of prayer,' but you have made it a den of thieves," or, according to another Gospel, "a house of trade." The church of God is turned into a den of thieves when robbery, murder, adultery, perjury, sacrilege, heretical inventions and other evils are practiced within it. When its leaders burn with greed and when cheap or not so cheap palliums [the distinctive mantle worn by archbishops] possess the riches formerly of kings. Hence, he infers, "I who am, I have seen it, says the Lord." In other words, "My eyes have beheld what you thought was hidden. The darkness of your treasures do not escape my consciousness." He who, though he was rich, became poor for our sake, is now ashamed at our riches and says, "Woe to you wealthy, who have your consolation now!"”

“Wherefore, brethren, if we do the will of God our Father, we shall be of the first Church, that is, spiritual, that hath been created before the sun and moon; but if we do not the will of the Lord, we shall be of the scripture that saith, "My house was made a den of robbers." So then let us choose to be of the Church of life, that we may be saved.”
