Be on your guard against error

^20-23 God has given you all a certain amount of spiritual insight, and indeed I have not written this warning as if I were writing to men who don’t know what error is. I write because your eyes are clear enough to discern a lie when you come across it. And what, I ask you, is the crowning lie? Surely the denial that Jesus is God’s anointed one, his Christ. I say, therefore, that any man who refuses to acknowledge the Father and the Son is an anti-christ. The man who will not recognise the Son cannot possibly know the Father; yet the man who believes in the Son will find that he knows the Father as well.
