I think he is bowing with respect to the wife of a leader of the country as a gentleman.
Christ didn’t act from what we read in the Gospels like he was on a throne here on earth either.
I open doors for women, maybe nod to people and greet them with a “good day”. Showing signs of accessibility and respect isn’t the worst in life IMO.
So all Popes do this, this is just another goofy media tale?
Yes, Christ was humble, but did he bow to unbelievers?
yes but you know exactly how this plays in the muslim world. they give two craps about what Christ did or didn’t do. they see a leader of another religion bowing to muslims.
