The unusual Catholic custom of adding "S.A.G." to letters

This centuries-old tradition is something to consider when you're sending parcels or letters.
Father Karl A Claver
St. Anthony, a priest, is much more powerful.
Maria delos Angeles
Yes, but priests are also usually the least of all men.
Abbé Jean-Marie du Divin Coeur de Jésus
Today the belittle St. Anthony, tomorrow they will belittle Jesus.
Maria delos Angeles
Carlo Acutis was baptised at my local church, 4 min walk away, so he will be my guide for the internet, B.C.G.
Naomi Arai
Only unusual to Novus Ordos. It's quite common in tradition.
Abbé Jean-Marie du Divin Coeur de Jésus
Thanks for sharing a Catholic Tradition. J.M.J.
