Identifying False Teachers and Teachings

Matthew 7:15-20

15 “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves.

16 By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles?

17 Likewise, every good tree bears good fruit, but a bad tree bears bad fruit.

18 A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit.

19 Every tree that does not bear good fruit is cut down and thrown into the fire.

20 Thus, by their fruit you will recognize them.

Matthew 16:5-12

5 When they went across the lake, the disciples forgot to take bread.

6 “Be careful,” Jesus said to them. “Be on your guard against the yeast of the Pharisees and Sadducees.”

7 They discussed this among themselves and said, “It is because we didn’t bring any bread.”

8 Aware of their discussion, Jesus asked, “You of little faith, why are you talking among yourselves about having no bread?

9 Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered?

10 Or the seven loaves for the four thousand, and how many basketfuls you gathered?

11 How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees.”

12 Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.

I John 4:1-6

1 Dear friends, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.

2 This is how you can recognize the Spirit of God: Every spirit that acknowledges that Jesus Christ has come in the flesh is from God,

3 but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.

4 You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.

5 They are from the world and therefore speak from the viewpoint of the world, and the world listens to them.

6 We are from God, and whoever knows God listens to us; but whoever is not from God does not listen to us. This is how we recognize the Spirit of truth and the spirit of falsehood.
