His sermon was divided into four principal parts. The first was a short and brief declaration concerning the evangelist. The second was of the interpretation of the good seed; and because he called the Word of God the good seed, and heresy the evil seed, he declared what heresy was and how it should be known. He defined in this manner: "Heresy is a false opinion, defended with pertinacity, clearly repugning to the Word of God." The third part of his sermon was concerning the cause of heresy within that realm and all other realms. "The cause of heresy," quoth he, "is the ignorance of those who have the cure of men's souls. To them it necessarily belongeth to have the true understanding of the Word of God, that they may be able to win again the false doctors of heresies, with the sword of the Spirit which is the Word of God; and not only to win again, but also to overcome, as saith Paul, 'a bishop must be faultless, as becometh the minister of God, not stubborn, nor angry; no drunkard, no fighter, not given to filthy lucre; but harberous,[84] one that loveth goodness, sober minded, righteous, holy, temperate, and such as cleaveth unto the true word of the doctrine, that he may be able to exhort with wholesome learning, and to improve that which they say against him.'" [84] Hospitable. The fourth part of his sermon was as to how heresies should be known. "Heresies be known on this manner. As the goldsmith knoweth the fine gold from the imperfect, by use of the touchstone, so likewise may we know heresy by the undoubted touchstone, that is, the true, sincere, and undefiled Word of God." At the last, he added that "heretics should be put down in this present life. The Gospel appeared to repugn this proposition--'let them both grow unto the harvest.' The harvest is the end of the world: nevertheless, he affirmed, they should be put down by the civil magistrate and law." [Sidenote: A fed Sow accuses and curses Master George.]
