It's lonely to be a priest. It just is. But in a certain and very real sense this is necessary. The priest has to know something of the loneliness of Jesus in the garden of Gethsemane, because this is where we see the classic expression of the perfect unity of his human and divine wills.
For us who are mixed in our motivations, it will be our daily practice and cooperation with grace that will bend our will to the divine. As with Jesus in the garden, it is in our own loneliness that we see this task before us most clearly. Our experience of alone-ness can be either the occasion of the sin of turning back on ourselves and indulging in loneliness, or turning from ourselves in the solitude that reaches out to the One who is.
