The young Pope says that he renounces his fellow men and women because it is easier to love God than to love humans. He said that he was incapable of withstanding the suffering brought on by loving human beings. He said to the Swiss girl, that it would be wonderful to love her the way she wanted to be but it was impossible because he is not a man, he is a coward.
I think what he said was beautiful. And maybe it is beautiful because it is true.
