What is my Achilles’ heel — the one weakness that keeps me from fully turning toward God? In this Lenten meditation, Fr. Paul Donlan reflects on St. Josemaría’s call to continual conversion, emphasizing that the Christian life is not a one-time commitment but an ongoing, demanding transformation that requires identifying and confronting our most persistent fault, often rooted in one of the seven capital vices. Using the image of Achilles’ vulnerable heel, he challenges listeners to examine their conscience, cooperate actively with God’s grace, and strive to become true “salt of the earth” and “light of the world,” shining through concrete effort and daily struggle. Lent, Fr. Paul urges, is a powerful season to make a decisive step forward into acknowledging our weaknesses, desiring change, and courageously partnering with God to pursue deeper holiness.
