A DOG AND A PIG
But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire. (II Pet. 2:22)
Here is a passage that may hold interest for alot of people. We first must ask the question; Who is Peter talking about? Who is the "them"?
For the answer, we must go all the way back to the very first verse in the chapter. He is talking about false teachers. These false teachers were ‘privily’ introducing damnable heresies into the Church. Privily means in secret and by stealth, introduce something foreign, such as strange gods. Heresies is very interesting. It literally means, ‘a school of opinion’. Hence, the teachings are based upon these false teachers opinions, not the Word of God. What is the motivation of these false teachers? Covetouness! These men, motivated by greed and coveting, with feigned words, make merchandise of the people of God. Feigned, comes from the word, ‘plastos’, meaning something that is well-formed. Yes, you guessed it. That is where we get the word , plastic from. These men use well-formed, nicely crafted PLASTIC words to bring the people of God into their snare. They desire to ensnare the people of God, “to make merchandise” of them. To make merchandise, simply means, ‘to make use of a thing or person for gain’.
In short, these false teachers, motivated by greed, are secretly introducing strange opinions, with well-crafted words, in order to use the people of God for their own personal gain. And in addition to this, because of them, “the way of truth shall be evil spoken of”. Because they profess to be numbered among the true believers, the Way of Truth is blasphemed. Does any of this sound familiar? This is a prophetic utterance concerning the so-called, Prosperity Gospel. Or at least those who use this prosperity teaching to milk the people of God, in order to line their own pockets. Peter says that these are, denying the Lord that bought them, and bring swift destruction upon themselves.
A dog turns to its own vomit because it is in its nature. A pig wallows in the mire, because it is in its nature. Peter is pointing to the fact that these men, who teach things contrary to the Words and Spirit of Jesus, were never changed in their nature. They had always been a dog and always a pig. You can teach a dog tricks, but he is still a dog and will turn to his own vomit. You can dress and clean up a pig, but it will always head for the wallow. Why? Because it is in their nature.
It had been better for them to have never heard the Truth, because it shall not fair well for them in the day of Judgment.
