It does vary by jurisdiction. Our lodges tend to have a very large Bible and other VSLs get placed around it representing the faiths of the members. If 2-3, the other VSLs are opened, but only the central one has a S&Q on it. Sometimes, if worried a VSL might fall off due to a large central VSL on a small pedestal, we do not open the others, especially, during a degree when the presence of the candidate's own VSL means there is a shortage of real estate on the altar. I've never seen anyone get precious about this concerning their own VSL, but occasionally some PMs insisting that a member's VSL gets placed and opened so all faiths of all members of the lodge are represented. A few years ago we had a Muslim master, he was obligated on the Koran, but just relied on the Lodge's Bible during meetings. At the end of the day we're not in Church or casting some spell around relics and icons, he would have been happy because the symbolism was met. I actually really do not know our rules on this (unusual) and don't have much interest in looking them us in case I find something I don't like - I'm happy to act by precedent and common sense rather than rule.. and I would be a guy a Master or Sec or DC would ask if they wanted guidance on this in the middle of a meeting I was attending....
