Jeanne at Catholic Fire has a great post on St. Augustine, whose feast is today, as well as his mother St. Monica, whose feast day was yesterday. I wonder if these two are the only mother-son saints.
My favorite quote of St. Augustine, "our hearts are restless until they rest in Thee".
And my favorite quote about him comes from St. Ambrose, to whom St Monica often came in tears about her stubbornly sinful son, "talk to God about Augustine, not to Augustine about God". This is sage advice for those of us with family members outside the Church who will not listen to our pleas for their conversion.
