"Amen, amen, I say to you, he who does not enter through the door into the fold of the sheep, but climbs up by another way, he is a thief and a robber.
For this reason, thus says the Lord about the prophets who prophesy in my name, whom I have not sent, who say: 'Sword and famine will not be in this land.' By sword and famine those prophets will be consumed.
Behold, I am against the prophets, who dream what is false, says the Lord; who explain and so seduce my people with their falsehoods and with their miracles, though I did not send them, nor did I command them. They have offer nothing beneficial to this people, says the Lord.
And truly, in what way will they preach, unless they have been sent, just as it has been written: "How beautiful are the feet of those who evangelize peace, of those who evangelize what is good!"
For ones such as these do not serve Christ our Lord, but their inner selves, and, through pleasing words and skillful speaking, they seduce the hearts of the innocent.
But there were also false prophets among the people, just as there will be among you lying teachers, who will introduce divisions of perdition, and they will deny him who bought them, the Lord, bringing upon themselves swift destruction.
And in avarice, they will negotiate about you with false words. Their judgment, in the near future, is not delayed, and their perdition does not sleep.
Most beloved, do not be willing to believe every spirit, but test the spirits to see if they are of God. For many false prophets have gone out into the world.
