'a morbid surge of the love that terrified him'

His normal way of looking on Bishop was as an x signifying the general hideousness of fate. He did not believe that he himself was formed in the image and likeness of God but that Bishop was he had no doubt. The little boy was part of a simple equation that required no further solution, except at the moments when with little or no warning he would feel himself overwhelmed by the horrifying love. Anything he looked at too long could bring it on. Bishop did not have to be around. It could be a stick or a stone, the line of a shadow, the absurd old man’s walk of a starling crossing the sidewalk. If, without thinking, he lent himself to it, he would feel suddenly a morbid surge of the love that terrified him—powerful enough to throw him to the ground in an act of idiot praise. It was completely irrational and abnormal.

He was not afraid of love in general. He knew the value of it and how it could be used. He had seen it transform in cases where nothing else had worked, such as with his poor sister. None of this had the least bearing on his situation. The love that would overcome him was of a different order entirely. It was not the kind that could be used for the child’s improvement or his own. It was love without reason, love for something futureless, love that appeared to exist only to be itself, imperious and all demanding, the kind that would cause him to make a fool of himself in an instant. And it only began with Bishop. It began with Bishop and then like an avalanche covered everything his reason hated.
