If I recall correctly, Saudi Arabia does not allow Bibles to be brought into their country.
That's just the least of it. When we were stationed there in 1980-82, there was a rather sizeable Catholic community, composed of Americans, Europeans, Eritreans and Filipinos. The ONLY place Mass could be celebrated was on an Embassy ground, and at one point, the Interior Minister, a prince, shut down the Masses at the Belgian Embassy. From that point on, only the U.S. Embassy was able to host a very limited number of communicants in the auditorium. There were two priests to serve the entire community, one American and one Filipino. Just before we left, the Saudi government pulled the visas for both priests. We couldn't call them "priests," but had to call them "welfare officers"; we couldn't call them "father" but had to address them as "uncle." There was a team at Lockheed City composed of lay people who filled in for the priests. My loathing for all things Saudi is deep and abiding.
