It’s nine months until we celebrate the birth of Jesus and today is the Feast of the Annunciation.
I believe that the moment of conception is the moment a human being, made in God’s image, a person with an immortal soul, is created by God. For a Christian no other view stands up to scrutiny; no other view is logical.
Today, then, we celebrate the moment when God himself became fully Man while remaining fully God. Jesus emptied himself, taking the form of a servant, being born in the likeness of men. He emptied himself to the extent that he became a microscopic clump of cells embedded in the womb of one of his creatures.
Jesus came into the world at the moment of his conception.
Merry Christmas.
