I am not sure if this is the right place to post this, someone please move it if it should be somewhere else.
How does a priest become a papal diplomat? Does he apply himself (with permission from his bishop)? Does the bishop send him to be trained? Some other way? I’m mostly just curious because the former Vicar General of my home diocese left his post to join the Diplomatic Service of the Holy See.
Thank you and please excuse my bad English!
