Because they have not known the Father - See on John 15:25; (note). Ignorance of the benevolence of God, and of the philanthropy of Christ, is the grand fountain whence all religious persecution and intolerance proceed.
See John 15:21.
“The angel of the Lord by night opened the prison doors, and brought them forth, and said, Go, stand and speak in the temple to the people all the words of this life.” We see here that the men in authority are not always to be obeyed, even though they may profess to be teachers of Bible doctrine.

And then these leaders, in the blindness of their minds, give full sway to what is supposed to be righteous indignation against the ones who have set aside cherished fables. They act like men who have lost their reason. They do not consider the possibility that they themselves have not rightly understood the word. They will not open their eyes to discern the fact that they have misinterpreted and misapplied the Scriptures, and have built up false theories, calling them fundamental doctrines of the faith.
