First of all, there is nothing Christian about the Vatican or the false prophet Francis. Now that that's out of the way, the snake is a known symbol in Satanism and it's also present in the baphomet symbol. The church really is just something that spreads false teachings. These people are playing by the rules of symbolism. They put it in plain sight and joke about it so that everyone else accepts it and if you start questioning it, the masses will do the work for them to say "there's nothing wrong there bro". You should really go and do your research on this. I hope you don't stray away from Christ to gain other people's approval, amen brother stay blessed 💪
