Have you seen it happening? Any old sergeant or a low ranking second lieutenant... sees coming towards him a fine-looking recruit, of an incomparably better quality than the officer; but the salute and its return are still given.
Meditate on the contrast. From the tabernacle of that church, Christ, perfect God, perfect Man, who has died for you on the Cross and gives you everything that you need... approaches you. And you go by without paying any attention to him.
