I like the idea. The rube would be if the Catholic church follows suit. The yellow and white flag is that of the Catholic church and it is also the flag of a sovereign state. According to what I’ve read, no flag should or will fly higher than the US flag. The exception is the flag of the UN. Since the Vatican flag is both a country’s flag and a religious flag, how would that be allowed. Personally, I would have no problem with it flying above the US flag.
The UN flag should not be flown higher than the national flag.
As the un flag is not elected government, i will use it for toilet paper when i run out of the koran.
