It may be asked how I know that the Devil knew that Christ was God. My answer is found in the same chapter. There is an account of what a devil said to Christ:
"Let us alone. What have we to do with thee, thou Jesus of Nazareth? Art thou come to destroy us? I know thee. Thou art the holy one of God." Certainly, if the little devils knew this, the Devil himself must have had like information. Jesus rebuked this devil and said to him: "Hold thy peace, and come out of him." And when the unclean spirit had torn him and cried with a loud voice, he came out of him.
So we are told that Jesus cast out many devils, and suffered not the devils to speak because they knew him. So it is said in the third chapter that "unclean spirits, when they saw him, fell down before him and cried, saying, 'Thou art the son of God.'"
In the fifth chapter is an account of casting out the devils that went into the swine, and we are told that "all the devils besought him saying, 'Send us into the swine.' And Jesus gave them leave."
Again I ask: Was it necessary for the devils to get the permission of Christ before they could enter swine? Again I ask: By whose permission did they enter into the man?
Could personifications of evil enter a herd of swine, or could personifications of evil make a bargain with Christ?
In the sixth chapter we are told that the disciples "cast out many devils and anointed with oil many that were sick." Here again the distinction is made between those possessed by devils and those afflicted by disease. It will not do to say that the devils were diseases or personifications.
In the seventh chapter a Greek woman whose daughter was possessed by a devil besought Christ to cast this devil out. At last Christ said: "The devil is gone out of thy daughter."
In the ninth chapter one of the multitude said unto Christ: "I have brought unto thee my son which hath a dumb spirit. I spoke unto thy disciples that they should cast him out, and they could not."
So they brought this boy before Christ, and when the boy saw him, the spirit tare him, and he fell on the ground and "wallowed, foaming."
