But simple as the Sign of the Cross is, it carries a brave weight: it names the Trinity, celebrates the Creator, and brings home all the power of faith to the brush of fingers on skin and bone and belly. So do we, sometimes well and sometimes ill, labor to bring home our belief in God's love to the stuff of our daily lives, the skin and bone of this world -- and the Sign of the Cross helps us to remember that we have a Companion on the road.
