Recently I shared Francis's tips for being a good father, but my atheist friends do not consider Pope as authority as I do and are asking what is pope's expertise with parenthood?
By expertise I mean education or work with children, child psychologists, psychiatrists.
I read Wikipedia but found nothing relevant. I also know about Our Father book but it will not be strong evidence for Pope's experience by my friends. What I did for now was to explain that author is irrelevant and one should reason about content, not about author.
