A while back, I read a post, (I wish I could remember where) in which the blogger said she preferred "Holy Ghost" to "Holy Spirit" because the former referred to a Person, while the latter could be some kind of amorphous, pantheistic force, such as "May the Force be With You!" She recognized that some might have problems with the word "ghost" because of popular connotations of haunted houses and Casper the Friendly Ghost and so on.
Do you have any thoughts on why you might prefer one or the other? I find I personally like the use in a liturgical setting, but I am unlikely to speak about the third Person in the Trinity as the Holy Ghost, but maybe I should rethink that.
