The Church has saints from every tribe, language and people. Some of these holy ones are surrounded in obscurity, others are popular for specific cases (thank you, Saint Anthony, for your help in finding my car keys), and then we have the superstar saints. These are the ones that everyone knows.
Of course, Mary and Joseph are at the top of the list, but there’s also the likes of Saint Patrick (compliments of the Irish missionaries throughout the world) and Saint Christopher (who doesn’t even have a declared feast day anymore).
Truth be told, it’s hard for any saint to make it to the top tier. Certainly, more contemporary saints have some chronological odds against them. And yet, we see some surprise exceptions. It seems everyone knows Saint Maria Goretti (who admittedly had an Italian advantage) and it appears that the universal body of believers is also really getting to know and fall in love with Saint Josephine Bakhita, who came from Sudan in Africa.
