August is the month dedicated to the Immaculate Heart of Mary. Normally pictured as a flaming heart surrounded by a wreath of flowers and pierced by swords, the heart of Mary is mentioned twice in Scripture.
Thine own soul, a sword shall pierce. Luke 2:35
Mary kept all these words, pondering them in her heart. Luke 2:19
The Immaculate Heart of Mary symbolizes Mary's interior life of perfect obedience to the will of God. She accepted the sorrows dealt to her in this life, and continues to intercede for us in the life to come.
