Think about it. Whenever we meet a new person, it is common to introduce ourselves. Names help us to identify each other. They organize a bundle of characteristics, and attributes about an unknown other, so that we can begin to know them as a particular person. And different names carry different associations.
Names are important.
Naming, associating a word with some idea or experience, reveals that Word has the power to shape our reality. And it is fortuitous to hear these two Gospel accounts of Jesus' beginnings side by side. Look at the two Gospels again, first in Luke. Curiously, the two common questions that I am being asked must have been burning questions of expectant parents in his time, too. Luke, with careful detail, records that the archangel Gabriel comes to Mary in the sixth month of Elizabeth's pregnancy.
