The book of Ezekiel, chapter 23 contains adult expressions, many people feel uncomfortable reading. You don't usually read such words in a holy book.
What does the Catholic church say about it?
This is not a simple issue as you might think. This video is the reason why I ask the question. That is an Egyptian Christian channel, the program is for a Muslim audience, it talks about what's wrong with the Quran and encourage them to convert to Christianity.
The host was talking about sex in Islam, and how Mohammad married teenagers, a Muslim called and he told the host to read that chapter, the host said I can't do that on Air. All is shown in the video.
What happened afterwards is that Muslims are using that chapter to make fun of the bible, and it got serious. We can't blame them either, the vocabulary used is shocking. Maybe not to you, but to a society not open minded, that chapter could be damaging.
Note that the whore is not just a simple word in Arabic, you know honor killing?
I'm not sure if you know what I'm talking about but I would hope that some pope or priest realized the magnitude of this problem, and tried to address it.
