Today we celebrate the Memorial of St. Dominic, founder of the Order of Preachers or the Dominicans, priest. I’m A Dog Mom I Was Born With A Fire In My Soul And A Mouth Shirt! Dominic was born to Spanish nobility of the house of Guzman. His mother was Blessed Joan of Aza who, when pregnant, had a vision that her unborn child was a dog who would set the world on fire with a torch carried in its mouth. A dog bearing a torch in its mouth became a symbol for the Dominicans. Dominic founded the Order of Friars Preachers in 1215, a group who lived a simple, austere life, and an order of nuns dedicated to the care of young girls.
