The following quote is from a news article, which you can read in full at

Begin quote:
A Swedish nun who saved Jewish families during World War II was canonized by Pope Francis in a ceremony at St Peter’s Square on Sunday, the NNC reported.
Mary Elizabeth Hesselblad, a Lutheran who converted to Catholicism, is Sweden’s first saint in more than 600 years.
Hesselblad, a former nurse, is credited with saving at least 12 Jews during the war by concealing them inside the Rome convent where she was the mother superior. The Jews remained hidden for about six months until the end of the war.
End quote
Excuse me! I don’t believe that, saving only 12 Jews, warrants sainthood. There were 6 million Jews killed in the Holocaust. Why couldn’t she have saved a few more Jews?
According to the news article, this is Sweden’s first saint in 600 years. Maybe if there had been more Jews in Sweden, there would have been more saints. Saving a gentile gets you nothing, as far as I know.
My favorite saint is St. Jude, the patron saint of lost causes.

St. Jude – the patron saint of lost causes
When you think that everything in your life is hopeless, pray to St. Jude; he will get you through it.
