This is why Catholics genuflect when they come to church. They know that this is a holy place, and to be found on one’s knee is a very good posture in such precincts. It says, ceremonially, not verbally, ‘I am a creature and thou art my Creator. I am thy child and thou art my Father. I am a subject and thou art my Sovereign. And, alas, I am a sinner, and thou art holy.’ To kneel, only briefly, in this fashion is to order one’s body as well as one’s mind to what is true.
