what the Bible has to say

Together we will explore what the Bible has to say about Halloween, providing food for thought as you decide for yourself on the issue.

I don’t understand the above sentence. Does it mean Together we will explore what the Bible MUST say about Halloween, …?

No, the “has” there is possessive and is not the “has” of “has to”.

It simply means “explore what the Bible says about…”

  1. What does the Bible say about X?
  2. What does the Bible have to say about X?

#2 distances the speaker from “what the Bible says”: it implies objectivity, on the speaker’s part.

Best wishes,

Your reading, of course.

  1. What does the Bible have to say about X?

Or to put it another way: it has an air of “wishing to assess what the Bible says”.

MrP

Are you saying that is characteristic of the “have to say” form?

I think it best to wait and see if Sitifan has any questions about the replies so far. An arcane discussion between two native speakers might confuse matters.

And if his reply to your posts was “OK, thanks”, what would be your reaction?
