:Yes, it does.  Many Jews, even those who aren't aware that there's a prohibition involved, feel acutely uncomfortable saying the name of the Christian god.  I doubt I'd be able to find you a reliable source for that widespread phenomenon, largely because it doesn't seem all that productive to publish a book about it when we're living in a predominantly Christian society.  That's why I can't say it in the article.  But I can say it here on the talk page.  I've seen people write Jeezus, just to avoid writing his name.  In the middle ages, he was referred to as "that man".  Common usage among English speaking Orthodox Jews is "Yoshke" or "Yushky", and there are even Hebrew books where Yeshu is spelled with a mark that identifies it as an acronym (יש"ו as opposed to ישו).  -   -
