A confessor told me this story the other day, after making sure there wasn't anyone else in line for confession:
Once when he was superior of a large house, a brother was sent away to one of those places where priests and religious brothers and sisters go to deal with addictions or other serious life issues. When he was about to be released, the superior went to collect him.
While the head psychologist was discussing the brother's after-care needs with the superior, he received a phone call. To give him some privacy, the superior walked over to the office window. As he looked out on a beautiful spring day, he saw a number of priests and brothers and nuns walking about in silence in the yard below. Some were praying the rosary and some were reciting their office. They all looked holy to the superior, and he was edified by such a scene that seemed to give so much glory to God.
When his phone call was finished, the psychologist joined the superior at the window.
"Whatever is wrong with them individually, there is only one thing the matter with all of them," said the psychologist.
"Oh?" responded the superior.
"Not one of them has a friend in the whole world; no one to even shed a tear if they were to die," the psychologist continued.
The story illustrates a critical hazard of the spiritual, and especially the formal religious life. It's necessary that we pray and practice our devotion to God in the quiet of our hearts. But if we aren't also interested and devoted to other people, and if we don't allow them to love us in turn, we have wandered into a pseudo-spiritual blind-alley, cheated ourselves out of the good news, and have not believed in the God who is revealed in the utterly human life of Jesus Christ. And in this state we will be easy prey for all of the addictions and substitutes for God that the world tries to force upon us each day.
