We operate with the assumption that giving people new ideas changes people. It doesn’t. Believing ideas is, in fact, a way of not having to change in any significant way, especially if you can argue about them. Ideas become defenses.
If you have the right words, you are considered an orthodox and law-abiding Christian. We burned people at the stake for not having the right words, but never to my knowledge for failing to love or forgive, or to care for the poor. Religion has had a love affair with words and correct ideas, whereas Jesus loved people, who are always imperfect.
You do not have to substantially change to think some new ideas. You always have to change to love and forgive ordinary people. We love any religion that asks us to change other people. We avoid any religion that keeps telling us to change.
