I pronounce jesus as "jeezes". My wife, a catholic school teacher, says I say it wrong.
Well, I would assume that she knows how to pronounce it so you should listen to her.
What gives her the right to correct me?
She is just trying to help you. It's important to get things like that right.
The name is not that important to me.
It does not have to be important to you, but she is just trying to help you pronounce it. Try to get the name right if you can.
