It is in St Luke's Gospel that we hear the infant narratives recounting the birth and early childhood of Christ. It is the one gospel where we probably hear the most about our Blessed Mother. This is with good reason; Luke most likely heard these stories from Mary herself. So while he may have never met Jesus in person, he heard much about Him from the best source there could be~ Jesus' own Mother.
As we celebrate this great saint's feast day today, let us ask his intercession for the parts of our lives that are still in need of healing, be it physical, emotional or spiritual.
