Happy feast day of the Hammer of Heretics!
Here are some writings and art concerning St. Anthony of Padua: http://www.franciscan-archive.org/antonius/.
I didn't know he was a Doctor of the Church until I realized yesterday's Mass was the "Os justi" for Doctors.
He's considered the "Doctor of the Gospel"; see ch. 22 of 35 Doctors of the Church (https://isidore.co/calibre/browse/book/5924).
