The St. Monica novena starts tomorrow! According to praymorenovenas.com, she is the patron saint of alcoholics, married women, mothers, wives and difficult marriages (also, evidently, abuse victims). She is the mother of St. Augustine, once a wayward non-Christian who converted after she prayed on his behalf for 17 years. St. Augustine is of course now a Doctor of the Church, a revered theologian and philosopher. His feast day is coming up on August 28. St. Monica's feast day is August 27, which is the day after this novena ends.
Are there any people or situations in your life in need of prayer? Give them up to St. Monica's intercession in faith. Perhaps take some time, too, to meditate on the struggles in her life and how prayer helped her overcome - always a good lesson to remember in our own lives.
