Oh I'm sure he'll be told that it's the VP but why would he know anything about Biden's faux Catholicism or anything about Pelosi and the American bishops sure as heck aren't going to fill him in.
We like to think the U.S. is the center of the universe but the world is a big place. There are parts of the world where Christians are being slaughtered by Muslims. The Curia is a pit of vipers. The homo-socialist bishops are hanging on to power throughout the entire Church. The Chinese government is appointing bishops. Our national politics are not high on the Pontiff's priority list.
Seems there would be staff in the Vatican who would know about high ranking us pols especially those who are catholic
Let’s be real, he would be an idiot not to know who the President and vice-President of the United States is, he probably even knows little things like who Putin is, and David Cameron.
It is pretty hard to be an educated, well read man with a global perspective who does not even know who leads the most powerful nation on earth, and is fighting Muslims all over the world.
