I decided to read the entire session and there are curious things there, considering the present BLM protests and the denigrating and degrading of white people and the attack on Christianity, etc
Well, if we are speaking about flags, and considering Laura's question about going to Europe, don't forget Russian flag as well.Country flags have symbol
There are all kind of interpretations of the Russian flag (red, blue, white), like earth/soil/spilled blood, blue sky and white clouds. And other symbolic meanings.
But apparently Russians like to use the phrase of "white sky, blue sea". For example, there are poems here and here, that talk about the love for Russia or about the Russian flag, and they use this combination.
Also in relation to christianity, what Edgar Cayce said about Russia comes to mind.
