On Tuesday the Church celebrates the great feast of the Annunciation. We recall the visit of the Archangel Gabriel to the Virgin Mary. Her 'yes' begins the whole process of our salvation through Christ, and from that moment our humanity is being taken up into the godhead.
But Mary's 'yes' wasn't blithely or quickly given. As you can see if you read the story (Luke 1, 26 - 38), she puts the Archangel through something of a cross examination! Her questioning is not however out of doubt but out of faith. She is astounded that God should choose her to begin the completion of his plan of salvation.
In the same way, our faith isn't something that means that we never question the messages and messengers that God sends us. It's only by doing so that we can grow in our appreciation and understanding of what they really mean. An unexamined faith isn't really worth very much at all.
Mary is always our example in the ways of faith, and her conduct at the Annunciation is a perfect example. She listens, she questions, and then she consents. So too with us, we are called to hear the message, we probe and question and ponder it, and then we say our 'yes' to the tasks that God has for us. May Mary, woman of faith, pray for us.
