“For tell me, I pray you, what is the use of showing statues walking, dogs of brass or stone barking, mountains dancing, of flying through the air, and such like things, which you say that Simon did? But those signs which are of the good One, are directed to the advantage of men, as are those which were done by our Lord, who gave sight to the blind and hearing to the deaf, raised up the feeble and the lame, drove away sicknesses and demons, raised the dead, and did other like things, as you see also that I do. Those signs, therefore, which make for the benefit of men, and confer some good upon them, the wicked one cannot do, excepting only at the end of the world. For then it shall be permitted him to mix up with his signs some good ones, as the expelling of demons or the healing of diseases; by this means going beyond his bounds, and being divided against himself, and fighting against himself, he shall be destroyed. And therefore the Lord has foretold, that in the last times there shall be such temptation, that, if it be possible, the very elect shall be deceived; that is to say, that by the marks of signs being confused, even those must be disturbed who seem to be expert in discovering spirits and distinguishing miracles.
