By Joe Sixpack, The Every Catholic Guy, Church Militant - When we recite the Creed, there's one required thing I hardly ever see anyone do. The Nicene Creed says, "For the sake of us men and for our salvation, He came down from Heaven, was made flesh by the Holy Spirit from the Virgin Mary and became man." During this sentence, we're supposed to bow (except at Christmas Mass, when we kneel). The reason we do this is to pay homage to the fact of the Incarnation — when God became man.
